HPC Wire taps work of two Blue Waters researchers


Dec 18, 2019

The trade journal HPC wire tapped Jon Calhoun and Luke Olson in its December 2019 report on notable new research on high-performance computing community and its related domains. In their paper, "FaultSight: A Fault Analysis Tool for HPC Researchers", the authors present a fault injection analysis tool that they claim can efficiently assist in analyzing HPC application reliability and resilience scheme effectiveness. Calhoun, a former Blue Waters graduate fellow who is an assistant professor at Clemson, and Olson, a professor at the University of Illinois at Urbana-Champaign, wrote the paper with Einar Horn and Dakota Fulp. "FaulrSight" was one of six papers presented at 2019 Workshop on Fault Tolerance for HPC at eXtreme Scale, which took place within the Supecomputing 2019 annual conference, better known as SC '19.

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.
