Pegasus is a tool to help workflow-based applications function in various environments, including desktops, cloud, and high-performance computing (HPC) systems. It was designed to allow scientists to construct workflows in abstract terms and remove the need to understand the underlying execution environment. Pegasus has been used successfully in a number of scientific fields: astronomy, bioinformatics, earthquake science, gravitational-wave physics, ecology, and cryo-EM, amongst others. A workflow in Pegasus consists of multiple tasks with defined dependencies, and Pegasus handles job submission, data staging, execution ordering, and failure recovery. Some beneficial features of Pegasus include:

• Data Management: Pegasus handles data transfers, input data selection, and output registration.
• Automated Error Recovery and Reliability: Errors are automatically addressed by retrying tasks, workflow-level checkpointing, re-mapping, and trying alternative data sources for data staging.
• Adaptability and Reuse: Pegasus works in a variety of distributed computing environments, and workflows can easily be run in different environments without alteration.
• Scalability: Pegasus can scale both the size of the workflow and the resources the workflow is distributed over without impacting performance.

Pegasus is deployed on Anvil through the Anvil Notebook Service, which provides browser-based access to Jupyter Notebooks running on Anvil infrastructure. The Pegasus Notebook environment includes the Pegasus workflow management system, HTCondor for workflow execution management, and preconfigured integration with Anvil’s SLURM scheduler. This environment allows users to develop and debug workflows interactively using the Pegasus Python API or command-line tools, submit workflows to Anvil’s batch system using their allocations, and monitor workflow execution and logs directly from the notebook interface. No additional Pegasus installation or configuration is required by the user.

The Beyond the Algorithm Challenge was designed by the NASA Earth Science Technology Office (ESTO) to propel scientific discovery for complex Earth Science problems—in this case, rapid flood analysis—by encouraging the exploration of unconventional and innovative computing methods. Specifically, the ESTO wanted participants to utilize technologies such as quantum computing, quantum machine learning, neuromorphic computing, or in-memory computing, which have all shown promise in overcoming limitations of conventional computing methods. By testing these novel computing methods, the Beyond the Algorithm Challenge paves the way for transforming how Earth Science problems are solved, potentially improving the lives and safety of the American people.

The SECQUOIA group is a Purdue University research organization within the Davidson School of Chemical Engineering. Led by Dr. David Bernal, Assistant Professor of Chemical Engineering, the SECQUOIA group focuses on designing and implementing optimization algorithms using hybrid and cutting-edge hardware technologies, including quantum computing technologies. Upon learning about the Beyond the Algorithm Challenge, Bernal felt that the competition aligned well with SECQUOIA’s work and immediately began assembling a team. Team members for the challenge included: Dr. Bernal, Yirang Park, PhD student in Chemical Engineering; Alan Yi, sophomore in Computer Science; and Daniel Anoruo, senior in Computer Science with a cybersecurity focus from Towson University.

Over the course of 10 weeks, the group designed and refined QUAFFLE (Quantum U-Net Assisted Federated Flood Learning and Estimation). QUAFFLE is a hybrid modeling framework that combines Quantum U-Nets for image segmentation with federated learning, a machine learning approach that decentralizes the training process. To understand the reasoning behind QUAFFLE requires a rudimentary understanding of these architectures and techniques.

U-Net architecture is a tried-and-true convolutional neural network (CNN) used for pixel-level image segmentation. The name stems from the fact that when drawn, the architecture takes the shape of a “U.” U-Nets take images and identify specific objects within those images. The resulting accuracy of the U-Net model correlates with how well it was trained.

Federated learning is a technique in which a global model is collaboratively trained across multiple devices or servers, each of which has its own local model. One of the benefits of federated learning is that each local model can handle a specific type of data—ideal for tasks that involve analyzing dissimilar data. The performance of the global model is improved in this scenario by producing higher-quality training results on smaller, distributed datasets rather than relying on less robust results from one large, centralized dataset.

For the Beyond the Algorithm Challenge, the SECQUOIA group wanted to create a system that was capable of producing accurate flood maps. The group theorized that harnessing the power of quantum computing combined with federated learning would allow for this while improving speed, security, and efficiency, compared to traditional computing methods.

A major obstacle for the group was mismatched datasets. The flood maps would need to be based on all available imagery, which includes images of differing regions, sizes, and sources (LiDAR, drone, satellite, weather radar, etc).

“One of the main challenges we had with this specific application was that there's a lot of heterogeneity in the data,” says Yirang Park. “To overcome this, we implemented federated learning under a heterogeneous-client setting, where each client trained locally on a random subset of the data and contributed model updates to a shared QUAFFLE model, improving speed and accuracy.”

Another issue the group faced in this challenge is the computational intensity required for flood detection. The very large, heterogeneous datasets needed for the task means that there is a significant amount of training parameters. More training parameters equals more computing power and longer computing times. To combat this, the group decided to replace the bottleneck layers in the U-Net architecture (the layers forming the bottom of the “U”) with quantum layers. The idea was that this would help reduce the number of training parameters required, thus reducing the training time and increasing learning efficiency.

“We theorized that if we needed fewer training parameters, we could speed up the training process,” says Daniel Anoruo. “Replacing the bottleneck with quantum-based architecture allowed us to do that while simultaneously improving feature extraction.”

The final challenge for the group was one of access and scarcity. For now, quantum computers are rare and few researchers are allocated computing time on the machines. The SECQUOIA group used the Anvil supercomputer to solve this problem by simulating two types of quantum computers: a gate-based system (with PennyLane software) and a photonic-based system (with ORCA-SDK software). The benefits of using a powerful supercomputer like Anvil to simulate a quantum computing system were manyfold: the researchers tested and refined QUAFFLE on a computing system they had access to, validated their approach for potential future use on different types of quantum systems, and bypassed the long process of obtaining an allocation on a quantum computer just to test an unproven (at the time) software framework.

“Running these simulations on Anvil gave us an advantage in the sense that we know QUAFFLE is hardware agnostic,” says Park. “There are multiple types of quantum computers, and no one knows which one will be the system, but we do know that QUAFFLE can adapt to different hardware architectures.”

Park continues, “Having a working code that has been proven in simulations and can adapt to various quantum systems has also allowed us to de-risk the approach. We know that we haven’t built something only to find that we’ve wasted time and resources after implementing it on precious quantum resources.”

The SECQUOIA group was thrilled with Anvil’s performance.

“Anvil really saved us,” says Alan Yi. “We tried testing these simulations on our local computers, and they would run for two days and not be done. But with Anvil GPUs, the simulation would finish really quickly, sometimes even less than an hour.”

After completing their work, the group had demonstrated that QUAFFLE was a success—it required 6% fewer parameters and outperformed a centralized quantum U-Net in accuracy when combining different data sources. Their innovative approach led to them securing a position as a finalist in the Beyond the Algorithm Challenge. While they did not ultimately receive the grand prize in the competition, the team’s work stood out for its innovation and real-world potential. QUAFFLE earned recognition from the judges as a promising solution, and the project gained valuable support from industry leaders, including Rigetti, Orca UK Computing, Flower, and IBM. The team plans to continue expanding QUAFFLE, and hopes to someday test it on an actual quantum system.

Paridha Talmale is a Master’s student at Purdue, majoring in Engineering Management. Last October, thanks to assistance from a WHPC scholarship, Talmale attended WE25, an annual international conference hosted by the Society of Women Engineers (SWE). Founded in 1950, SWE is a global STEM community dedicated to empowering women in the field of engineering. We sat down with Talmale after she attended WE25 to discuss the conference and learn about her experiences whilst there:

Can you describe your overall experience at the conference?

Attending the SWE Conference has always been an incredibly inspiring and empowering experience for me. Being surrounded by thousands of women engineers, leaders, and innovators created a strong sense of community and belonging. I had the opportunity to attend sessions on leadership, innovation, and emerging technologies, as well as connect with professionals from top companies. Beyond the technical learning, I found it motivating to hear personal career stories that reflected resilience, creativity, and purpose. The environment was both energetic and inclusive, reinforcing my passion for engineering management and my goal of combining technical problem-solving with strategic leadership.

What was your biggest takeaway from the conference?

My biggest takeaway was the importance of networking with intention and authenticity. Through meaningful conversations with professionals in the fields of technology, manufacturing, and energy, I gained valuable insights into different career paths and how leadership in engineering is evolving with AI and sustainability. The career fair also helped me better understand what companies value in candidates beyond technical expertise. Skills like adaptability, communication, and systems thinking stood out as critical for long-term success. Overall, the conference strengthened my vision of contributing to innovation in technology by working along with diverse, collaborative teams.

Did you have any fun or exciting experiences outside the planned conference sessions?

Apart from the conference sessions, I took some time to explore the city of New Orleans. I enjoyed Italian cuisine with fellow Purdue MEM attendees at Italian Pie, tried the city’s signature beignets at Café Beignet, and explored iconic locations such as Caesars Casino and Bourbon Street, which added a memorable cultural experience to the trip.

Has your experience led you to consider future involvement in research computing or HPC, either as a field of study, a career path, or a member of the community?

Yes, this experience has encouraged me to consider future involvement in research computing and high-performance computing (HPC). Exposure to the scale, impact, and collaborative nature of HPC highlighted how critical these systems are in enabling data-driven research and complex problem-solving across domains. As a Master’s student in Engineering Management with a strong interest in technology and analytics, I see value in engaging with the HPC community, whether through applied projects, interdisciplinary collaboration, or roles that bridge technical teams with strategy and operations. This experience has broadened my perspective on how HPC can align with my long-term career interests.

How did support from Purdue WHPC make this experience possible for you, and how do you feel about receiving the support?

The support from Purdue WHPC was instrumental in making this experience possible. Without their assistance, attending such a large national conference might not have been feasible for me this year. It was not just their financial support, but it acted like a golden ticket that allowed me to fully immerse myself in the sessions, networking events, and the career fair without any added stress. I am genuinely grateful for their encouragement and commitment to empowering women in engineering and computing. This experience not only expanded my professional network but also deepened my sense of belonging in a community that uplifts and supports women pursuing technical leadership roles.

Would you recommend the WHPC scholarship program to other Purdue students and why?

Yes, I would wholeheartedly recommend the WHPC scholarship program to other Purdue students. The program not only provides financial support to attend transformative events like the SWE Conference but also connects students to a broader network of women in technology and research computing. WHPC provides financial support to various other conferences and events as well. It’s an excellent opportunity for students to gain exposure to emerging fields, engage with leaders in STEM, and develop both technical and professional skills. Beyond funding, WHPC’s mission of empowering women in high-performance computing and related disciplines fosters confidence and encourages students to take active roles in advancing diversity and innovation in engineering.

Would you please describe any prior involvement with Research Computing and/or WHPC?

Although I have not directly worked with Purdue’s Research Computing team or at the Envision Center, I have applied computational and analytical tools extensively in both academic and professional settings. My experience includes using Python, SQL, and simulation platforms like Arena to analyze data, model systems, and optimize processes, skills that align closely with high-performance and data-intensive computing. Currently, through my operations optimization experience with Panasonic Energy, I work on data-driven problem-solving and process improvement initiatives. This involves analyzing manufacturing performance metrics, identifying inefficiencies, and using computational models to optimize workflows that bridge engineering principles with analytics and operations research.

I became involved with Purdue Women in High Performance Computing (WHPC) when I applied for their scholarship to attend the SWE Conference, and I see this as the beginning of a longer-term engagement. The organization’s mission to empower women in computing strongly resonates with me, and I hope to contribute by promoting awareness of computational and analytical tools among interdisciplinary engineering students, especially those in management and applied engineering fields.

Can you introduce yourself and share a little about who you are? Hello! My name is Nathan Whitacre and I’m a senior working at RCAC as a student programmer.

What are some of your main interests or passions? Some of my interests include video game development, learning Spanish, and listening to EDM.

Can you tell us about your role at RCAC? What does your job entail? I am a Student Programmer at the Envision Center, where I create applications and solutions for our clients that normally involve computer vision or data visualization technology. I’ve also organized several game jam events on behalf of the Envision Center and SIGGD, a game development club here at Purdue.

What do you enjoy most about working at RCAC? I love the people and culture at the Envision Center. I’ve gotten the opportunity to learn so much from the awesome people that I work with, and they really make me feel at home there. It’s also just super cool that not only do I get to learn new technologies and skills, but I get to use what I learn to make things that provide real value to people.

Tell us more about your favorite project you like to show off!

Project title: SIGGD's "Echoes of Isovios: A Legacy Undone"

Project description: Echoes of Isovios is an action-packed story-driven roguelite game with a supernatural twist: You can let ghosts of the past possess you to gain their unique game-changing abilities. In the game, you play as Orion, a tyrant who has driven humanity to extinction using the mythical sword, Isovios. After eons of isolation, you are granted the power to go back in time and right your wrongs at three distinct points in history, each taking place at a pivotal moment of your tyrannical reign. Echoes of Isovios was developed over the course of a year by Purdue ACM’s Special Interest Group for Game Development (SIGGD).

What did you learn from this project? This project took a diverse team of very talented people to complete, including programmers, gameplay designers, artists, composers, audio producers, writers, and voice actors. I was the lead gameplay designer for the project, so along the way I learned many skills required for managing a project of larger scope and collaborating on a multidisciplinary team. The biggest lesson I took away from this project is that, on large teams, communication is everything. Having more people working on a project can lead to increased productivity, but only if everyone on the team is on the same page. Making sure everyone on the team is on the same page is so important for making these large-scale projects work. When they do work, it’s the coolest thing to be a part of.

Did you get to showcase this anywhere?
We were able to showcase a demo of the project at Fractal 2025, a student-run CGT expo, and the game is available to play on SIGGD’s website at https://purduesiggd.github.io. The game will soon be released in an updated state on Steam!

Dark matter is elusive. We don’t know what it is or what it is composed of. This mysterious material scoffs at the adage “Seeing is believing”—it does not interact with the electromagnetic force, meaning it neither absorbs, reflects, nor emits light of any kind. We literally cannot see it, yet we know it is there. Dark matter has mass, thereby exerting the effects of gravity on visible matter. It is only by observing these gravitational effects that scientists know dark matter exists. In fact, dark matter accounts for roughly 85% of all matter in the universe, serving as a cosmic scaffolding that organizes galaxies at scale. Without it, galaxies would have long ago been torn asunder by their own rotational velocities, lacking the necessary gravitational pull required to hold together.

As one can imagine, studying a material that can’t be seen but whose effects must be observed through a telescope can be tricky. For decades, scientists have tackled this problem by running cosmological simulations that include dark matter and comparing them to what is actually seen in the universe. If the end result of a simulation matches the physical reality seen through the telescope, then that’s a good sign that the scientists are on the right track with their theories. If not, the theory must be altered or dismissed entirely. Recent technological advances have enabled scientists to study dark matter in greater depth than ever before. High-performance computing (HPC) systems provide an astonishing amount of computing power, while the new James Webb Space Telescope (JWST) gives astronomers an unprecedented view of the universe, enabling observations of the first stars and formation of the first galaxies after the Big Bang. This boost in data-gathering ability and computing performance lies at the heart of the dark matter research being conducted at UCLA.

Claire Williams is a PhD student in the Astronomy and Astrophysics Division of the UCLA Department of Physics and Astronomy. Williams’s focus is on theoretical astrophysics. She is part of the Supersonic Project, a collaboration that studies how stream velocity and dark matter affected galaxy formation in the early universe. In this instance, stream velocity refers to the relative velocity of baryons and dark matter during the early formation stages of the universe. The stream velocity has been largely neglected in traditional simulations of galaxy formation. However, recent findings show that the stream velocity was supersonic, which had major implications for how the baryons and dark matter were distributed. Williams’s, and the rest of the research group’s, goal is to improve our understanding of the galaxy formation process by including the stream velocity as a factor in their cosmological simulations.

“So our specific studies are trying to gain a more precise understanding of the process by including effects that previously nobody included,” says Williams. “People already had dark matter, they already had gas, but they were missing the stream velocity. It has been largely ignored because it is challenging to get right in simulations. But neglecting the fact that material was moving past the dark matter at five times the speed of sound inevitably leads to a different result. What our group has done is to run simulations that correctly include the relative motion of dark matter and ordinary matter at early times in the universe.”

Williams and her research group utilize the Anvil supercomputer to run high-resolution AREPO hydrodynamics simulations for a number of different studies. The common theme across these studies is that the group runs theoretical simulations both with and without stream velocity as a factor, and that the results are, or will soon be, compared with JWST observations. The size of the regions being simulated are, quite literally, astronomical, ranging upwards of two megaparsecs. This equates to a volume slightly larger than the Milky Way and Andromeda galaxies combined. The simulations are also incredibly detailed, with each individual particle representing an area roughly 200 times the mass of our sun. For comparison, that’s a single grain of sand on the beach. Simulations this large require a massive amount of computing power and would be impossible without HPC resources like Anvil.

“So we're simulating a region larger than the whole Milky Way, but our individual pieces that are moving around are only a couple 100 times bigger than our own sun,” says Williams. “This is why we need Anvil, because you couldn't run this on your laptop. This takes a couple of weeks to run on the cluster.”

Running the simulations is only the first part of the process; HPC resources are further needed to actually analyze the data. Williams continues:

“Then, at the end of the day, when you finish your simulation run, you basically have a bunch of imaginary particles in an imaginary box. But you have to figure out, ‘How would these particles translate to light that the telescope would see?’ So you need to post-process the simulations, which involves extensive data analysis and specialized algorithms to convert the resulting particles into light in space. We need Anvil for this data analysis as well.”

The end result of the group’s computational work is a theoretical picture of what the universe should look like to us today, as viewed through the JWST. Dark matter was dispersed throughout the universe soon after the Big Bang, unaffected by the forces of electricity and magnetism. The gravitational pull of dark matter led to clumps of particles, which eventually formed into galaxies. And the precise placement of these galaxies was likely influenced directly by the stream velocity. At least, that’s Williams’s hypothesis. Now, the research group must wait to see if it proves true.

“So one of the things that we have found with our studies,” says Williams, “is that the stream velocity should cause some very faint galaxies to shine very brightly for a brief period of time at the beginning of the early universe, because it causes them to form a bunch of stars all at once. Without the stream velocity factored in, you wouldn’t expect to see this happen. And now they're starting to make observations with the JWST that should show what we predict to see. So, hopefully, in the next few years, we can get confirmation from the telescope that this effect is happening.”

Williams continues, “One thing that's kind of cool is that if they don't see that effect, then it poses a big problem for dark matter in general, because all of our models so far are dependent on how we think dark matter should work. So if we make this prediction and the telescope doesn't see it, then we know we've messed up our collective understanding of dark matter along the way and may need to make changes to things we thought we had a grasp on in our cosmology.”

Shalini Kumari is a Master’s student at Purdue, majoring in Engineering Management. Last November, thanks to assistance from a WHPC scholarship, Kumari attended GHC 25. GHC, eponymously named after pioneering computer scientist Grace Hopper, is the world’s largest gathering of women in tech, bringing together thousands of women from across the globe to learn, network, and celebrate their achievements. We sat down with Kumari afterwards to discuss the conference and learn about her experiences whilst there:

Can you describe your overall experience at the conference?

GHC felt like stepping into a space buzzing with possibility. Everywhere I turned, there were women building, leading, and lifting each other up. It was inspiring in a way that stayed with me long after the sessions ended.

What was your biggest takeaway from the conference?

When women come together, something shifts, confidence grows, barriers feel lighter, and the future feels a little more in reach. Being surrounded by thousands of talented women reminded me that leadership in tech isn’t just something to aspire to; it’s something women are actively shaping right now. I met so many inspiring people and attended sessions like Aditi Patange’s “Code to Strategy: Transitioning from SWE to PM,” which made me realize that there are others with backgrounds like mine carving similar paths. It was grounding and motivating in the best way.

How did support from Purdue WHPC make this experience possible for you, and how do you feel about receiving the support?

The support from Purdue WHPC genuinely changed what this experience looked like for me. It made attending GHC possible and allowed me to focus on learning, connecting, and exploring new career paths with an open mind. I’m deeply grateful; it felt like having a team behind me, cheering me on. Would you recommend the WHPC scholarship program to other Purdue students and why? Absolutely! The WHPC scholarship doesn’t just help you attend a conference, it gives you access to a community that pushes you to grow, learn, and imagine bigger possibilities for yourself. It’s an opportunity I hope more Purdue students take advantage of.

Did you have any prior involvement with Research Computing or WHPC?

This was my first time engaging with WHPC. It was a wonderful introduction, and I’m excited to stay connected moving forward!

Dr. Ziran Wang is an Assistant Professor of the Lyle School of Civil and Construction Engineering and leads the Purdue Digital Twin Lab. He recently worked with the Envision Center, a group within RCAC’s Research Software Engineering (RSE) Center, on an INDOT project aimed at improving driver understanding and acceptance at innovative intersection designs within the state of Indiana.

Intersections can be challenging for drivers. Traditional signalized and two way stop control intersections present right angle conflicts that sometimes result in poor safety performance. According to the U.S. Federal Highway Administration, roughly one-quarter of traffic fatalities and one-half of traffic injuries occur at intersections. Of course, intersecting roadways are unavoidable and quite necessary. So to reduce the risk of intersection accidents, a nationwide push for new, thoughtful intersection designs has led to the development of “innovative intersections.” Innovative intersections are designed to enhance safety and improve traffic flow by reducing or modifying conflict points—locations where the paths of two or more road users intersect—within an intersection. There are numerous types of innovative intersections that have proven to reduce accidents and fatalities, yet very few of these novel designs have been integrated into our roadways. The problem is inherent to the solution itself: new designs are unfamiliar to drivers, leading to unease, confusion, and public resistance. To help ease this general discountenance of innovative intersections, Wang wanted to develop a driving simulator for INDOT that would allow the general population, as well as key policymakers, to experience proposed intersection designs in a risk-free setting.

“Innovative intersections are a proven solution,” says Wang, “but getting the public at large to accept them as well as learn to use them appropriately is a challenge. Our goal is to meet this challenge by giving people a chance to experience these intersections without having to be driving at speed on the roadway.”

Wang reached out to the Envision Center for help with this project. Together, the team developed the “Portable Driving Simulation Platform.” This platform is a Unity game engine-based simulator that provides an immersive, interactive environment for users to try out new intersection designs without ever having to set foot inside a vehicle.

The Portable Driving Simulator Platform involves five kinds of innovative intersections: a displaced left turn (DLT), a reduced-conflict intersection (RCI), a diverging diamond interchange (DDI), two-lane roundabouts (RAB), and roundabout interchanges (RBI). Three-dimensional maps of these five intersection types were developed by the team, as well as multiple car models and both first-person and third-person viewpoints for users to experience. The group also implemented traffic signals and collision avoidance algorithms into the simulator.

“This was a fun, collaborative project,” says George Takahashi, Principal Visualization Scientist at the Envision Center. “We [the Envision Center] focused our efforts on developing the environment and 3D work design, while Dr. Wang and his graduate student, Luyang Jiang, worked on the driving mechanics, vehicle behavior, and simulation programming. Thanks to this shared development, we now have a solid foundation to build upon new driving scenarios and explore more collaboration opportunities in the future.”

Now that the first iteration of the Portable Driving Simulation Platform has proven successful, the group intends to further enhance the simulator for INDOT. Future work plans include integrating steering wheel and paddle user controls and overall optimization and beautification, to make it feel as realistic as possible. Eventually, Wang would like to see this platform used across Indiana with widespread deployment at BMV branches, and as a fundamental testing platform for traffic analysis.

“This collaboration with the Envision Center has totally revolutionized the way we conduct digital twin research. We used to spend much time identifying appropriate off-the-shelf platforms for conducting simulation studies on intelligent transportation systems, and now we can build our own easily with a proven pipeline. ”

Project title: Handling Apps tickets at RCAC

Project description: I handle tickets from the wide range of users that Purdue's multiple clusters cover and support. Whenever issues arise, I would be one of the first people to handle the ticket then I'd handle their issues, noting whatever arises in RCAC's database.

What did you learn from this project? A lot of patience, especially from (slightly, and understandably) upset researchers who thought they had lost their life's work (thankfully they hadn’t!).

Dr. Iman Haqiqi is Lead Research Economist in the Department of Agricultural Economics at Purdue University. His research leverages high-performance computing (HPC) resources to study international trade, environmental, and resource economics, with a focus on global change and sustainability. Recently, Haqiqi utilized Anvil, one of Purdue’s most powerful supercomputers, to explore how strategic trade partnerships can buffer the risk of crop market volatility stemming from increased heat stress.

Heat stress is a significant concern for crop production. When plants are exposed to excessive heat for prolonged periods, they can exhibit numerous negative health effects, including inhibited growth, reduced photosynthesis rates, sunscald, wilting, and even death. Different crops exhibit varying levels of sensitivity to heat stress, but corn—a staple crop for billions of people—is particularly vulnerable. As extreme heat stress events increase in frequency and intensity, national and global food security is put at risk. Facing this challenge and understanding the effectiveness of alternative strategies to overcome it is precisely what drove Haqiqi to pursue his research.

Climate impact on average crop production has been researched to no end. There are many studies that look at the effects of heat stress or other extreme weather events on average corn yield. The problem, according to Haqiqi, is that looking at the average can be misleading and neglects a large part of the risk.

“A lot of other studies have looked at this problem and determined that, on average, crop production will be a little bit lower,” says Haqiqi. “But I find that looking at the average is misleading. Mixing extreme highs with extreme lows, for example, means that, on average, everything might be fine. What we need to do is study the volatility, because that’s where the real risk is. If we want to prepare, we have to measure the volatility, not just the average.”

While a small decrease in average annual corn yields may not be considered problematic, increased volatility is. Volatility always has been and always will be a factor in crop production. Some years will be worse than others. But as the risk of extreme weather events decimating a crop supply increases, so too does the chance that any particular season will cause the global supply of food, not to mention the agricultural market, to implode. Haqiqi’s goal was to investigate future volatility and risk in corn production associated with increased heat stress, as well as evaluate the effectiveness of two different adaptation strategies—irrigation and market integration.

Irrigation is a tried-and-true method of reducing crop vulnerability during periods of extreme heat. Not only does it cool the temperature of the plant, it also maintains appropriate soil moisture levels, which improves nutrient uptake, photosynthesis rate, and biochemical efficiency. The problem is that wide-scale adoption of irrigation as an adaptation strategy would further deplete an already strained resource—water. This concern over groundwater depletion has led to a growing interest in trade as an alternative option for offsetting crop volatility risk.

International trade partnerships between regions with differing climate patterns could reduce the risk of substantial losses to the national corn supply, but trade as an adaptation strategy had only been discussed in theory. Haqiqi wanted to measure the strategy’s effectiveness quantitatively. To begin, he needed to predict how corn yields would be affected by potential changes to the climate patterns. Haqiqi used a statistical panel model to estimate corn yield response to heat stress and then combined those results with NEX-GDDP-CMIP6 climate data to project future production volatility and risks of substantial yield losses. To assess overall volatility, Haqiqi needed to calculate the extreme heat levels (i.e., not the average) of each day for millions of fields worldwide, aggregate this for each growing season in every region that produces corn, and then aggregate this to determine global corn supply. Haqiqi then converted these from daily to yearly calculations and determined year-on-year changes in volatility. These results were then used to determine the risk of substantial loss of production for each region. Haqiqi also assessed the relative volatility of each region compared to the global market. Once these baseline results were obtained, Haqiqi could simulate multiple scenarios to analyze irrigation and market integration for their ability to reduce these future risks.

The results of Haqiqi’s research were clear: 1) corn yields will experience higher volatility due to increased heat stress; 2) irrigation expansion can offset this risk; 3) trade can also buffer the risk, but without depleting the groundwater supply. The third point is salient—according to the numbers, irrigation in the US will need to rise from 15% of farm land to 50-75% in order to maintain historical risk levels, which is unsustainable.

“So the whole idea of this paper was to show that, yes, there are some temporary solutions, like irrigation, but they are not sustainable,” says Haqiqi. “Something else, like international trade, which is a solution from an economic perspective, can have a similar effect in terms of reducing volatility and risk. But also, it has benefits because you don't need to have a lot of unsustainable use of resources.”

Haqiqi’s research required a massive amount of computing power, and for that, he relied on Anvil. The supercomputer was used for all computational tasks involving yield projection, variability analysis, and risk assessment.

“Without Anvil, this paper would be just a conceptual framework that, hey, you know, trade could be a good thing compared to irrigation,” says Haqiqi. “But we didn't have numerical evidence to support that claim. Now, thanks to having access to Anvil, we could provide that evidence.”

Haqiqi went on to note that the support he received from the Anvil team was exceptional and that because of the quick, comprehensive responses to his support tickets, he was able to rapidly move past any issues he had.

The results of Haqiqi’s research were published in Environmental Research: Food Systems. To view the publication and learn more about the study, please visit: Trade can buffer climate-induced risks and volatilities in crop supply.

High-performance computing (HPC) resources have proven indispensable for bioinformatics research due to several factors, including the massive size of the datasets used in life sciences, the computing power required for numerous research activities (analyzing DNA sequences for disease-related genes, cryo-EM based 3D reconstruction, etc.), and regulatory requirements. Life scientists have increasingly faced complex HPC environments, workflow tools, and large datasets due to a manifest shift in life sciences research, relying more heavily on sequencing data. And while having access to the computing hardware is essential, it's not enough—researchers also need to know how to use it.

Among various life sciences initiatives led by RCAC staff, RCAC scientists especially elevated support for Bioinformatics. Bioinformatics as a research discipline sits at the crossroads of biology and computer science. Often related to genetics and genomics, though not limited to this subfield, bioinformatics seeks to analyze and interpret biological data, which is typically packaged in large and complex datasets. Headed by Dr. Arun Seetharam, Lead Bioinformatics Scientist at RCAC, the development of the new bioinformatics support services has successfully contributed to broadening awareness and increasing adoption of HPC. Seetharam’s main focus for achieving this goal has been multifold: expand the bioinformatics software catalogue available on RCAC machines, provide world-class training appropriate for bioinformatics researchers and HPC users of all levels, and partner with researchers to enable new cutting-edge research.

“Our goal has been to make advanced bioinformatics accessible to every researcher at Purdue, regardless of their background,” says Seetharam. “Modern genomics workflows only reach their full potential when paired with high-performance computing, so our focus is on giving scientists not just the software, but the confidence and skills to run these analyses efficiently and reproducibly.” Seetharam continues, “Researchers often tell us that the hardest part isn’t the analysis itself, but navigating the tools and computing environments needed to do it well. By expanding our software catalog and building structured, hands-on training, we’re lowering that barrier and helping labs move from raw data to results much more quickly.”

In order to ensure compliance with data management and sharing policies that went into effect in 2025, RCAC deployed the Rossmann compute cluster and storage environment. As a NIST 800-171–aligned research resource, Rossmann features appropriate computing and data environments for research that involves level-3 restricted data, such as data subject to the NIH Genomic Data Sharing (GDS) policy and a spectrum of licensed data. Furthermore, RCAC launched a data management and facilitation service to ensure organized retention of research data, automate workflows, and guarantee researchers reliable access to raw results for current work and future needs.

Thanks to the efforts of several RCAC team members, RCAC now offers a diverse portfolio of Life Sciences Services to Purdue researchers. Some highlights of the team’s accomplishments from 2025 include:

1. Software & infrastructure

• Deployed Rossmann Community Cluster that is optimized for researchers running applications subject to heightened security requirements, such as data subject to the NIH Genomic Data Sharing (GDS) policy and licensed data.

• Deployed and actively maintain 750+ biocontainer modules across Negishi, Bell, Gautschi, Scholar, and Rossmann clusters.
• Built and deployed specialized environments, including RStudio biocontainer images and CellProfiler OOD applications.
• Provide ongoing workflow enablement and troubleshooting for Nextflow, Snakemake, and nf-core pipelines on RCAC systems.
• Expanded Globus data transfer and sharing tool to include High Assurance collections appropriate for Protected Health Information, Personally Identifiable Information, and Controlled Unclassified Information.

2. Datasets

• Updated iGenomes datasets are available as cluster-wide modules, providing standardized reference genomes for commonly studied species and eliminating the need for users to download or manage their own copies.
• Maintain centrally updated BLAST databases (nr, nt, RefSeq, SwissProt, and related sets) on all clusters to support high-throughput homology searches and downstream annotation workflows

3. Training, workshops & community programs

• Genomics Exchange (Spring 2025): 13 sessions; ~7 attendees/session; 77 cumulative participants.
• Genomics Essentials (Fall 2025): 12 sessions; 10–20 attendees per session; 10 sessions delivered; 100+ total participants.
• RNA-seq Workshop (Nov 20): served a large group of 35 researchers.
• Orientation for Biologists (Oct 16): Introductory HPC training session for 22 new life sciences researchers.

4. Cross-institutional engagement

• Upcoming Midwest Bioinformatics Showcase (Spring 2026), a joint Purdue–Northwestern seminar series highlighting graduate and postdoctoral genomics researchers across the Midwest and fostering cross-institutional dialogue, professional development, and HPC-enabled research. Abstract submissions open through January 16.
• Delivered plenary talk, titled “Responding to NIH Requirements for Controlled-Access Data” at the 2025 Trusted CI NSF Cybersecurity Summit.

5. Campus community building

• RCAC Genomics Discord server, now 50+ members, serving as a centralized communication and support hub for Purdue genomics researchers.
• Proposal support for 7 faculty (NSF, NIH P30/R35/MIRA/R01, NASA), including estimation of cost, consultation on sequencing strategy, workflow feasibility assessments.

6. Documentation & resources

• A newly launched RCAC Bioinformatics Tutorials Site, a comprehensive collection of bioinformatics guides, installation instructions, and RCAC-optimized best-practice workflows.
• RCAC Bioinformatics Resources page, which consolidates current and past workshops, training materials, and community programs.

While 2025 has been extraordinarily productive for the Life Sciences team at RCAC, Seetharam noted that there is no intent to slow down. The new year will usher in a new collection of Genomics Exchange workshops, running January through April. Also on the schedule is the Midwest Bioinformatics Showcase, a joint series between Purdue and Northwestern University, scheduled for the Spring 2026 semester. This seminar series will offer training and presentations led by select bioinformatics speakers from multiple institutions, with a goal of providing researchers the ideas, tools, and instruction they need to make an impact and ignite bioinformatic research in the Midwest region.

“The Midwest Bioinformatics Showcase is an opportunity to highlight emerging researchers and strengthen connections across institutions,” says Seetharam. “By bringing together students, postdocs, and faculty working on genomic and computational projects, we’re creating a space for collaboration that extends well beyond a single seminar series.”

Year: Senior

Major: Data Analytics, Technologies, and Applications

Position: Research Solutions Engineering Student

Can you introduce yourself and share a little about who you are? Hello! My name is Samuel Gomez, and I’m a Data Analytics student at Purdue University. I’m passionate about using data and technology to solve real-world problems and create meaningful impact. Beyond academics, I’m an active member of the Phi Kappa Phi Honor Society, a mentor in SHPE, and someone who enjoys helping others grow. My experiences span IT, data science, and project work across several industries, all of which have shaped my interest in building solutions that are both practical and people focused. Outside of my technical work, I enjoy soccer, the gym, and learning from the diverse communities I’ve been part of.

What are some of your main interests or passions? Some of my main interests include watching movies, playing soccer, going to the gym, and lately getting into running. Outside of school and work, I also enjoy photography and reading books on psychology, they help me learn more about people and spark a lot of my curiosity!

Can you tell us about your role at RCAC? What does your job entail? At RCAC, my role centers on developing and supporting solutions that improve how researchers use Purdue’s high-performance computing systems. Most recently, I designed and built a fully automated live-migration system for virtual machines on the Negishi cluster. This system integrates SLURM job scheduling with QEMU to seamlessly move VMs from node to node before job time limits expire, allowing them to run continuously with zero downtime. I also wrote the full internal documentation and an external white paper explaining the system’s architecture, automation logic, and usage, making it easier for both engineers and future users to understand and adopt the workflow.

What do you enjoy most about working at RCAC? What I enjoy most about working at RCAC is the people and the challenges. The team is incredibly supportive, knowledgeable, and always willing to help, which creates an environment where you’re constantly learning. I also appreciate the opportunity to work on complex, real-world problems that push me to grow technically and think creatively.

Tell us more about your favorite project you like to show off!

Project title: Negishi Recursive Migration System

Project description: My favorite project at RCAC is the automated recursive live-migration system I developed for the Negishi HPC cluster. The goal of the project was to allow virtual machines to run continuously on a cluster that enforces strict SLURM wall time limits. To achieve this, I designed a system that integrates QEMU live migration with SLURM scheduling so a VM can seamlessly “hop” from one compute node to another before its job expires. The system automatically launches new VM instances, monitors job runtimes, triggers full memory-state transfers, and sustains uninterrupted VM uptime across job boundaries.

What did you learn from this project? This project taught me how to design automation that fits within real HPC constraints while remaining reliable, policy-compliant, and user-friendly. I gained experience with QEMU internals, cluster networking, and advanced SLURM job orchestration, as well as how to build systems that can operate entirely without human intervention. I also strengthened my technical writing skills by documenting the full architecture, control flow, and implementation details for both internal engineering use and external audiences.

Did you get to showcase this anywhere? Yes, I will! My work is being shared in two ways:

1. Internal engineering documentation on Purdue RCAC’s GitHub for cluster staff and Research Solutions Engineers.
2. A publicly written white paper that explains the system in accessible terms for researchers, students, and anyone interested in HPC systems design. This will allow others to learn from the project and potentially adopt similar approaches on their own HPC environments.

In late 2024, Purdue unveiled its newest and most powerful supercomputer to date, Gautschi. The Gautschi cluster was designed to provide Purdue researchers with a world-class computing resource capable of driving the university toward its next giant leap. Eponymously named in honor of Walter Gautschi, Professor Emeritus of Computer Science and Professor Emeritus of Mathematics at Purdue University, the Gautschi supercomputer consists of two partitions—a traditional HPC resource focused on providing next-generation CPUs and a dedicated AI partition containing Nvidia H100 SXM GPUs.

Each year, supercomputers may be entered into benchmark competitions to test different aspects of their performance. For example, when Gautschi debuted in the Fall of 2024, it ranked number 157 on the Top500 list of the world’s most powerful supercomputers and number 43 on the Green500 list of the most energy-efficient supercomputers. This year, staff at the Rosen Center for Advanced Computing (RCAC) decided to measure Gautschi’s performance on the IO500 and HPL-MxP benchmarks.

The IO500 benchmark has become the standard for measuring HPC storage performance. It consists of five separate workloads to identify performance boundaries for HPC applications. On this year’s list, Gautschi was ranked 20th in the “10 Node Production” category, with a peak read performance of 186.54 GB/second. Only three other US university machines bested it on the benchmark. Gautschi also ranked 194th overall on the full list of IO500 submissions. Gautschi’s storage system is built with DDN’s Exascalar filesystem.

The HPL-MxP mixed-precision benchmark is tailored for testing a machine’s ability to handle artificial intelligence (AI) workloads. It combines testing parameters from the traditional HPL framework, one of the most popular benchmarks in the world, with AI-specific constraints. The HPL-MxP results are released biannually. Gautschi was ranked 27th overall on the November 2025 list, and was the top US university machine listed.

“We are excited to see how Gautschi stacks up against the world’s most powerful systems”, says Preston Smith, Executive Director of the Rosen Center for Advanced Computing in Purdue IT. “I/O performance is critical for AI computing to keep GPUs fed with data, and this benchmark score directly reflects the benefits Purdue researchers will get from using Gautschi. Using mixed-precision arithmetic allows HPC applications to leverage AI-optimized accelerators like GPUs, which use lower precision. Mixed-precision computing uses less power and allows for significant speed-ups, reducing time to science. Gautschi’s HPL-MxP score shows a more than 4x speedup on the same hardware simply by using lower precision arithmetic.”

The Gautschi cluster was built through a partnership with Dell, AMD, DDN, and Nvidia, thanks to support from Purdue Computes and the Institute for Physical AI (IPAI). Purdue researchers may obtain access to the Gautschi system through RCAC’s Community Cluster Program. For more information or to purchase access to Gautschi, please visit our Purchase Page.

Dr. Zhigang Feng is a professor in the Department of Economics at the University of Nebraska-Omaha. He, along with his collaborators hailing from multiple institutions, combined machine learning techniques with economic theory to tackle everyone’s favorite economic subject—taxes.

Taxation is an oft-debated subject for governments worldwide, with different opinions and theories as to what works best for individual countries or locales. How differing taxation strategies affect the economic choices of households in a population is an extraordinarily complex problem to solve. Many models have been developed to try and understand and predict the effects of taxes on the economy, with varying levels of success. Most models fail to account for household heterogeneity in the context of dynamic economic fluctuations. This shortcoming is precisely what Feng and his colleagues set out to remedy.

Research has long shown that household heterogeneity needs to be factored in to accurately model economic behavior and therefore design optimized fiscal policies. However, heterogeneity takes an already complex mathematical problem and adds in an infinite-dimensional object. Feng’s goal was to develop a novel machine learning-based approach that successfully factored in household differences. To do this required a massive amount of computing power due to the curse of dimensionality problem, which is why he and his collaborators turned to Anvil.

"This problem isn’t something traditional numerical methods in the standard economist's toolbox can handle—even with a handful of CPUs using MPI, let alone an average computer," says Feng. "We needed multiple GPUs running in parallel to harness the optimization power of modern AI techniques, and we needed them on demand. We also required a machine with massive memory to store the state of every simulated individual. Thankfully, Anvil was able to provide us with both."

The group utilized both CPUs and the advanced GPUs on Anvil to create a Markov decision process in Wasserstein space. They combined deep neural networks for equilibrium function approximation, a histogram-based distribution approximation, an analytically derived distribution transition kernel, and a modified value and policy iteration with an augmented Lagrangian method, all of which together allowed them to address the problem of infinite dimensions. After developing the new approach, the group also needed to run the model simulations for multiple scenarios, showing the cause-and-effect of different taxation strategies.

Overall the group was very happy with Anvil’s performance. The queue for the GPUs was short, allowing them the access they needed to quickly conduct their research. Feng also noted that anytime the team hit any snags or had issues, they reached out to the Anvil support team and received help promptly. All of this combined enabled the group to efficiently proceed with a project that otherwise would not have been possible.

“To solve these models, we needed Anvil,” says Feng. “There’s no question—without it, this is not something we would have been able to achieve.”

Though the research publication is in its preliminary stages, it shows promising results and will have important implications for policymakers and researchers wanting to design effective fiscal policies. The novel machine learning method developed by Feng and his colleagues is also scalable and can be applied to a wide range of other economic models.

SC25 is an annual conference where the brightest minds in computing and technology from around the world gather in one location for a week of communication, collaboration, and innovation. The conference took place in St. Louis, Missouri, this year, with 16,500+ attendees and a record-breaking 559 exhibitors. Purdue’s exhibitor booth, hosted by the Rosen Center for Advanced Computing (RCAC), did not disappoint, engaging with a steady stream of attendees who dropped by to speak with our HPC experts, listen to presentations, and participate in demonstrations.

The central theme for the Purdue booth this year was to promote the Purdue Computes initiative. To help achieve this goal, Purdue provided the conference with booth presentations throughout the week from experts within multiple departments. Purdue staff also participated in numerous workshops, Birds-of-a-feather sessions (BOFs), and panel discussions outside of the booth exhibits, all highlighting the university’s contributions to research computing and HPC in higher education. A full list of SC25 papers and presentations given by Purdue affiliates is as follows:

• Haniye Kashgarani, LJ Lumas, Emma Zheng, and Brendan Swanson: AnvilOps: Increasing Accessibility of Kubernetes with Automated Builds and Deployments
• Paul Jiang: A Formal Characterization of Non-Monotonicity in Tensor Cores
• Richie Tan and Guangzhen Jin: A Modular, Responsive, and Accessible HPC Dashboard Built upon Open OnDemand
• Mithuna Thottethodi, Sree Charan Gundabolu, and Vijaykumar T. N.: BLAZE: Exploiting Hybrid Parallelism and Size-Customized Kernels to Accelerate BLASTP on GPUs
• Elham Sarbijan, FNU Ashish, Christina Joslin, and David Burns: Generating Frequently Asked Questions from Technical Support Tickets using Large Language Models
• David F. Gleich: KVMSR+UDWeave: Extreme-Scaling with Fine-grained Parallelism on the UpDown Graph Supercomputer
• Petros Drineas and Vasileios Georgiou: Randomized Numerical Linear Algebra in HPC: Toward a Sustainable, Scalable Software Ecosystem

Aside from hosting a booth and giving presentations, Purdue assisted directly with making SC25 a success. Purdue staff and affiliates volunteered for the SC25 Planning Committee (the organizing body for SC25), SCinet (the collaborative group that builds the infrastructure and network for the conference), and the Student Cluster Competition (a 48-hour HPC competition). Thanks to these volunteers, Purdue lent its expertise towards building and running the entire conference. Support for SC25 wasn’t limited to employees, however. Purdue also offered hardware for a training session to help ensure the best conference possible.

Anvil, one of Purdue’s most powerful supercomputers, was the main resource used to host an all-day, student-focused workshop at SC25. The workshop consisted of lectures combined with self-paced hands-on activities on HPC, AI, and quantum computing. Each student created their own ACCESS account in order to utilize Anvil, and as a bonus for participating, they will have continual access to the supercomputer for a full year. The exercises mainly focused on accelerated code (CUDA) with both C++ and PyTorch, for which the students used all 84 of Anvil’s cutting-edge H100 GPUs for the entirety of the day. In total, more than 80 students from multiple institutions took part in the workshop.

SC25 also provided an opportunity for Purdue students to shine. Throughout the week, graduate and undergraduate students from the university were involved in numerous workforce development activities, including giving presentations at the Purdue booth, conducting workshops, and taking part in poster sessions. Two Purdue students competed as part of the INpack team in the 2025 IndySCC, a world-renowned supercomputing competition, while four of the eight Anvil REU students were able to present on the work they conducted during the summer program. Outside of gaining presentation experience, the students were also able to attend different informational sessions and learn about the latest advances in HPC, as well as network and develop connections with people within the community. Providing students with opportunities such as these ties in directly with Purdue’s goal of developing the HPC workforce of the future.

To cap off the fantastic week for Purdue, the new HPL-MXP mixed-precision benchmark list and IO500 lists were released at SC25. Purdue University’s newest supercomputing community cluster, Gautschi, was ranked 27th on the HPL-MXP list and 20th on the IO500 list in the 10 Node Production category. This is an amazing achievement and a testament to the value of Purdue’s continued investment in HPC.

Overall, SC25 was a tremendous success for the university. If you or someone in your department would like to be involved with SC26, please contact  rcac-help@purdue.edu.

Eight students from across the nation gathered at Purdue’s campus in West Lafayette, Indiana, for this year’s Anvil REU program. The students enrolled in this internship program to learn about high-performance computing (HPC) and to work on projects related to the operations of the NSF-funded Anvil supercomputer at Purdue. During the program, which is supported by the National Science Foundation (NSF), the students obtained the knowledge and skills necessary to build and support advanced research computing systems and scientific applications on these systems.

The Anvil REU program is a paid summer internship open to undergraduate students in the United States, regardless of their background. Due to a massive influx of applications—over 600 total—the application window closed early in mid-January of this year. This was a significant increase in applicants from 2024. The Anvil REU mentors—eight RCAC staff members who led the projects that the students would work on during the summer—along with the Anvil executive team, took this list of 600+ applicants and distilled it down to eight students. The eight participants of the Anvil REU program were:

• Abigale Tucker, Computer Science major, Middle Tennessee State University
• Randy Alejo, Computer Science major, Stony Brook University
• Brendan Swanson, Computer Science major, North Carolina State University
• Emma Zheng, Computer Science major, Purdue University
• Abigail Lin, Computer Science major, University of Florida
• Sadra Williams, Computer Science major, North Carolina State University
• Christina Joslin, Data Science and Applied Statistics major, Purdue University
• David Burns, Computer Science major, University of Wisconsin–Madison

The Anvil REU program consisted of four separate projects, with two students pairing together to tackle each one. These projects were chosen with real-world applicability in mind—the students would not only gain experience with HPC and learn new skill sets, but would simultaneously increase Anvil’s capabilities. Each project also had two mentors working with the students to help them achieve their goals.

Project 1:

The first Anvil REU project for 2025 focused on building a data warehouse to store and manage logs from data centers and compute systems, integrating data sources, and creating visual dashboards. Two students, Abigale Tucker and Randy Alejo, teamed up to take on this project under the supervision of their mentors, Sam Weekly and Patrick Finnegan, as well as Anvil Executive Team member Preston Smith. In this project, Tucker and Alejo built a data warehouse and several data pipelines that collect, transform, store, and enable the querying of data. The Anvil supercomputer supports over 12,000 users throughout the U.S. These users generate massive volumes of data encompassing a variety of scientific domains. Managing such a large amount of data is a difficult task, especially when it needs to be easily obtained at any point in the research process. Tucker and Alejo tackled this problem by designing a system to efficiently manage, process, and store this data, making it accessible, organized, and ready for analysis when it’s needed most.​ Their pipeline was developed using a tech stack that included Apache Kafka, ClickHouse, Apache Iceberg, Grafana, and Apache Superset. They tested their system by creating a testing environment that simulated the real architecture but used fake data, allowing them to validate and troubleshoot without risking the security of real researcher data or interrupting system processes that were already in place. Once they were pleased with the functionality and performance of their pipeline, they were able to connect it to real-world data on the Anvil system.

Project 2:

The second Anvil REU project worked on developing a dynamic web interface for building and deploying container workloads on the Anvil Composable Subsystem. Brendan Swanson and Emma Zheng worked on this project under the supervision of their mentors, LJ Lumas and Haniye Kashgarani, and Anvil Executive Team member Erik Gough. The Anvil Composable Subsystem is a Kubernetes-based private cloud that provides a platform for creating composable infrastructure on demand. This cloud-style flexibility provides researchers the ability to self-deploy and manage persistent services to complement HPC workflows and run container-based data analysis tools and applications. The problem is that deploying applications to Kubernetes can be really difficult, especially for beginners. To combat this issue, Swanson and Zheng developed AnvilOps, a user-friendly web interface that automates the deployment of applications to Anvil Composable without writing Kubernetes manifests. Thanks to their hard work throughout the summer, AnvilOps features seamles Git integration, the ability to monitor and deployments roll back to previous versions if needed, and supports a wide variety of languages and frameworks so users can connect their GitHub repository as-is. All of this allows for Anvil users of any experience level to deploy applications at the click of a button.

Project 3:

The third Anvil REU project focused creating easy-to-use bioinformatics workflow templates. Abigail Lin and Sadra Williams worked on this project with their mentors, Nannan Shan and Arun Seetharam, as well as Anvil Executive Team member Arman Pazouki. Genomics research that utilizes HPC resources has been accelerating in the past few years, which has been great for discovery in the field. However, biologists often lack a deeper understanding of computing and computational workflows, which can severely hinder (or altogether halt) their research projects. To aid in this issue, Lin and Williams developed four Bioinformatics Workflow Templates for genomics analyses, each tailored for Purdue’s Anvil HPC platform. The templates were: RNA-seq, variant calling, genome assembly, and general (a customizable option where users can easily create their own workflow). By completing their project, Lin and Williams have provided bioinformatics researchers with little programming knowledge a simple and easy way to conduct their science on Anvil.

Project 4:

For the fourth Anvil REU project, Christina Joslin and David Burns worked with their mentors, Elham Barezi, Ashish, and Anvil Executive Team member Carol Song, to add an automated document generation feature to TicketHub, a proprietary AI-enabled tool for user support staff. The scope of their project was to create a new feature that would proactively generate useful FAQs by using Natural Language Processing (NLP) and Large Language Models (LLMs) to identify and summarize common user issues from past user support requests. Maintaining accurate and up-to-date technical documentation is a time-consuming and heavily manual task for support staff at HPC facilities. By taking on this project, Joslin and Burns worked to remove some of the burden placed on Anvil’s support team. The students successfully developed this new TicketHub feature over the course of the internship, and ws able to test its performance by evaluating the generated FAQs in three key areas—clarity, accuracy, and relevance. The FAQs rated high in clarity, and had room for improvement in accuracy and clarity; however, the new feature proved to be very promising and work is ongoing to improve its performance and even extend its use beyond HPC.

A comprehensive educational experience

While the Anvil REU students worked day in and day out all summer, this program was more than a temporary job—it was a completely immersive learning experience. The REU students had access to their mentors and to the RCAC staff working on-site. On top of that, the students were able to take tours of the campus, attend presentations hosted by both RCAC and the SURF (Summer Undergraduate Research Fellowship) program, participate in technical workshops aimed at developing multiple skillsets (writing research abstracts, effective technical communication, etc.), and even attend the Practice and Experience in Advanced Research Computing (PEARC) 2025 Conference! The eight REU students also gave midpoint presentations on their projects to staff from the Pittsburgh Supercomputing Center (PSC), Lawrence Berkeley National Laboratory (LBNL), National Energy Research Scientific Computing Center (NERS), and Pacific Northwest National Laboratory (PNNL).

Aside from technical workshops and presenation experience, the REU students were able to take part in workshops dedicated to developing more intangible skills. One such workshop was led by Syd Moore, an Academic Advisor & Gallup-Certified Strengths Coach, and guided the group through the myStrengths talent assessment. Another was led by Matt Jones, Certified Master Facilitator in LEGO® SERIOUS PLAY® methods (LSP). This session introduced the students LSP, a facilitated thinking, communication and problem solving technique for use with organisations, teams, and individuals. Both of these workshops took place at the beginning of the summer and had a follow-up midway through to build on the lessons learned and further develop the students to prepare them for their future careers. Giving these students the opportunity to gain as much knowledge and experience as possible is a vital component of the Anvil REU program. In this way, RCAC can help to ensure that each one of the REU participants develops into a capable and competent cyberinfrastructure professional.

The Anvil REU program also scheduled ample amounts of time for socializing, fun, and relaxation. Thanks to the RCAC’s partnership with the SURF program, the REU students were able to attend multiple SURF Socials throughout the summer. This allowed the students to hang out with other undergraduates who were at Purdue for non-HPC-specific research projects, leading to new friendships and expanding their professional networks. Of course, the REU participants also socialized outside of these programmed events, but teaching them—by example—the value of having a positive work-life balance is an essential part of professional development.

Mission accomplished

On the final day of the Anvil REU program, the students presented their work to the Anvil team. As they demonstrated the results of their projects, each student discussed their accomplishments, obstacles, failures, and what they learned throughout the summer. The students were then asked questions and given them feedback on their presentations. To the Anvil team, it was wonderful to hear how this summer might help steer the future careers of these students, many of whom expressed a desire to continue within the field of HPC. Overall, these eight students made fantastic progress: they completed their projects, learned technical and interpersonal skills they will need in the workforce, and gained an in-depth understanding of the HPC world.

The platform extends nanoHUB’s success to deliver both open-source and commercial software that supports a semiconductor community through workforce development at scale.

• PURR: The Purdue University Research Repository (PURR) provides an online, collaborative working space and data-sharing platform to support Purdue researchers and their collaborators.

• MyGeoHub: A geospatial science gateway that supports the geospatial modeling, data analysis, and visualization needs of the broad research and education communities through hosting of groups, datasets, tools, training materials, and educational content.

• cdmHUB: The Composites Design and Manufacturing HUB (cdmHUB) is a collaborative web interface platform developed to host the simulation tools needed to advance composite materials design, certify product integrity, simulate manufacturing solutions, and accelerate the talent base of composite materials developers and users.

• Communityhub, Ghub, PlantingScienceHub, QUBES, Computational Infrastructure for Geodynamics, and the science gateway for NCSA’s Delta supercomputer are all science gateways powered by HUBzero.

Why HUBzero?

HUBzero is the platform to use for communities engaged in STEM. Collaboration is a defining feature of HUBzero. The platform enables users to create an environment where researchers, educators, and students can access simulation tools and share information. Anyone in a hub’s user community can utilize and contribute software which runs remotely on RCAC resources. Tools need not be installed on home computers, as everything on HUBzero is accessible via a web browser. A list of features and benefits of HUBzero includes:

• Researchers and students can connect applications, visualizations, and models to computing resources through a reliable and easy-to-use web platform.
• Peers can share research codes and receive a persistent interoperable identifier—a digital object identifier (DOI).
• Researchers, educators, and students can share knowledge and ideas in interactive spaces.
• Users can host interactive virtual learning opportunities for students and professionals.
• The platform provides open access to research products, community resources, curated curriculum, and more.

Each site that utilizes the HUBzero infrastructure is standardized with built-in user support features, statistics about users and usage patterns, and integrations with Google Drive, GitHub, and Dropbox. They also include interactive simulation tools, a simulation tool development area (including source code control and bug tracking), a Groups and Projects space for team collaboration and community building, an online course feature offering video seminars and animated presentations, and mechanisms for uploading and sharing resources.

IndySCC is a remote, cloud-based competition that runs parallel to the Student Cluster Competition (SCC) held each year at SC. Unlike the SCC, IndySCC does not require teams to build their own supercomputing cluster and bring it to SC. Instead, teams are provided with allocations on Jetstream2, an NSF-funded cloud resource hosted at IU, and are given ample time for practice and training in the months leading up to SC. IndySCC culminates with a 48-hour contest during which the teams are tasked with learning scientific applications, applying optimization techniques for their chosen architectures, and running an industry-standard benchmark on the supercomputer. This final phase of the competition takes place concurrently with SCC at SC, though IndySCC competitors are not required to compete in person at the event.

The 2025 IndySCC competition will see the return of the INpack team, a joint effort between Purdue and IU. This will be the first competition for the group since the 2023 IndySCC event. Of the six team members, five are new to the student cluster competition series, with one veteran returning from the 2023 team. The INpack team members for this year are as follows:

• David Piedra, Purdue University
• Dominic Yoder, Purdue University
• Gautam Hari, Indiana University
• Ryan Jacobson, Indiana University
• Sky Angeles, Indiana University
• Tri Nguyen, Indiana University

INpack began preparations for the competition in late August through asynchronous meetings and hands-on practice on Jetstream2. The group is working under the supervision of mentors from both universities: Charles Christoffer, Erik Gough, and Luke Monroe from Purdue, and Shawn Slavin (primary advisor) and Winona Snapp-Childs from IU. The team, including the mentors, came together for an in-person meet-and-greet and collaborative training session earlier this semester in Indianapolis. Another such meeting is scheduled for early November in Bloomington.

“IndySCC is a major professional development opportunity for the students,” says Christoffer. “Basically, this is a chance for the students to experience what RCAC and PTI do in a little microcosm. From the ground up, they learn how to build an HPC system and tune it to meet the performance needs of the applications. The experience gained alone is worth the time and effort, not to mention all the fun they have in the process.”

“The IndySCC is a great opportunity for students to work together to overcome many frequent challenges of research computing,” adds Slavin. “This partnership between Purdue and IU showcases the joint commitment to education and training the next generation of HPC workforce.”

Although teams can compete in IndySCC remotely, INpack will travel to St. Louis, Missouri, to participate in person and gain the full experience of the SC25 conference. The competition will take place November 17-19, 2025. To learn more about the IndySCC competition, please visit: https://sc25.supercomputing.org/students/indyscc/
