Purdue University

HUBzero, the web-based software platform for scientific collaboration, has returned to Purdue University. The platform’s infrastructure is hosted on resources at the Rosen Center for Advanced Computing (RCAC), and after a brief transition period, HUBzero is now live and in production at Purdue once more.

HUBzero is an open-source software platform for building powerful science gateways that host analytical tools, publish data, share resources, facilitate collaboration, and foster community building within a single web-based ecosystem. Initially developed by Purdue researchers as the Purdue University Network Computing Hub (PUNCH), it later evolved to be the platform known today as nanoHUB.org, and then generalized to the HUBzero platform and applied to dozens of science gateways using the platform.

From 2019 to 2025, HUBzero was operated out of the San Diego Supercomputer Center (SDSC) and returned to being led by Purdue in July 2025, back to where it all began. This move will help Purdue build upon its leadership in cyberinfrastructure for FAIR data, AI, and digital twins, and will lead to improvements in HUBzero as advancements made by Hubs at Purdue are made available to other Hubzero-based gateways.

All HUBzero gateways have been successfully transferred back onto the resources at Purdue and are operating at full capacity. The list of hubs currently hosted on the Hubzero platform include:

• nanoHUB: An open and free online platform for computational education, research, and collaboration in nanotechnology, materials science, and related fields. nanoHUB provides modeling and simulation tools and educational materials to the world to have impact in education and research. Also powered by nanoHUB, Chipshub is the online platform for everything semiconductors. 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.

HUBzero is the ultimate platform for scientific collaboration and education. With its return to Purdue, HUBzero is poised to continue delivering state-of-the-art resources to researchers and students, epitomizing the university’s persistent pursuit of innovation.
