Blue Waters Illinois allocations awarded to 26 research teams


Mar 7, 2017

Twenty-six research teams at the University of Illinois at Urbana-Champaign have been allocated computation time on the National Center for Supercomputing Application's (NCSA) sustained-petascale Blue Waters supercomputer after applying in Fall 2016. These allocations range from 25,000 to 600,000 node-hours of compute time over a time span of either six months or one year. The research pursuits of these teams are incredibly diverse, ranging anywhere from physics to political science.

18 general, 9 exploratory allocations on Blue Waters awarded to Illinois researchers


Nov 24, 2014

Eighteen researchers at the University of Illinois at Urbana-Champaign received allocations on the Blue Waters petascale supercomputer at the National Center for Supercomputing Applications (NCSA). A portion of available time on Blue Waters is reserved for University faculty and staff projects like these that require the system’s unique capabilities. Ten of the awards will continue projects already running on Blue Waters, related to a wide variety of topics like tornadoes, steel casting, and cell function, among others. Eight allocations are for new projects.
