National Science Foundation prepares for transition to eXtreme Digital generation of cyberinfrastructure

Purdue researchers needing assistance in applying for a TeraGrid allocation can contact Kim Dillman, Purdue’s TeraGrid Campus Champion. Dillman’s contact information includes: phone, 765-494-5446, e-mail,

Scientists, engineers, and other U.S. researchers have until midnight January 15, 2010, to apply for the next quarterly review of requests for free allocations of high-performance computer time, advanced user support and storage resources available on the TeraGrid through the National Science Foundation (NSF) Office of Cyberinfrastructure (OCI). To apply for an allocation of any size, visit TeraGrid’s online submission system:

Each quarter, a panel of computational experts, the TeraGrid Resource Allocations Committee (TRAC), evaluates requests primarily on the appropriateness and technical aspects of using TeraGrid resources. Applications received by the January 15 deadline will be considered at the March 2010 TRAC meeting, and awards will be available for the one-year period from April 1, 2010, through March 31, 2011. TeraGrid allocates more than 1 billion processor hours to meritorious requests each year. At the December 2009 TRAC meeting, 200 million processor hours and nearly a petabyte of data storage were awarded to 100 research teams. TeraGrid resources currently exceed 2 petaflops of combined computing capability and more than 60 petabytes of online and archival data storage from 11 resource provider sites across the nation, including Purdue.

For the next round of awards, researchers can request time on 15 systems, including TeraGrid’s two largest, which were funded under NSF OCI’s Track 2 Program—Ranger at the Texas Advanced Computing Center (TACC), and Kraken at the National Institute for Computational Sciences (NICS)—and the newest TeraGrid resource, the Longhorn remote visualization and data analysis system at TACC. Another remote visualization and data analysis system, Nautilus at NICS, will enter production in October 2010. For more information about TeraGrid resources, visit the resource catalog:

Purdue offers DiaGrid, a high-throughput computing, Condor-based pool of nearly 30,000 processors on the TeraGrid, along with services such as distributed rendering of high-end data visualizations and animations and a real-time satellite data portal.

TeraGrid, the NSF, and the TeraGrid Science Advisory Board are actively preparing for the transition to the next phase of NSF-supported cyberinfrastructure, called eXtreme Digital (XD), which will begin April 1, 2011. While a competition for the management of XD is ongoing, the program solicitation requires the winning team to provide continuity of service between TeraGrid and XD. To facilitate this, TeraGrid will provide transition documentation, training, consulting and application support services for three months beyond the start of XD. Allocations awarded at the June 2010 TRAC meeting will be the first to span both TeraGrid and XD (July 1, 2010, through June 30, 2011). For more information about XD visit the NSF/OCI web site:

About TeraGrid The TeraGrid, sponsored by the National Science Foundation Office of Cyberinfrastructure, is a partnership of people, resources, and services that enables discovery in U.S. science and engineering. Through coordinated policy, grid software, and high-performance network connections, the TeraGrid integrates a distributed set of high-capability computational, data-management and visualization resources to make research more productive. With Science Gateway collaborations and education, outreach, and training programs, the TeraGrid also connects and broadens scientific communities.
