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.

17 campus teams to accelerate their research with Blue Waters


Jun 10, 2015

Seventeen U of I research teams from a wide range of disciplines have been awarded computational and data resources on the sustained-petascale Blue Waters supercomputer at NCSA. “These diverse projects highlight the breadth of computational research at the University of Illinois,” said Athol Kemball, associate professor of Astronomy and chair of the Illinois allocation review committee. “Illinois has a tremendous pool of talented researchers in fields from political science to chemistry to engineering who can harness the power of Blue Waters to discover and innovate.”

Medley of Monte Carlo


May 28, 2015

What do superconductors and the intergalactic medium have in common? Scientists study both on Blue Waters using something called Monte Carlo methods. Monte Carlo methods are widely used in computational sciences because they allow researchers to find a solution to a problem that is intractable to answer directly. ... Robert Sugar, a professor emeritus at the University of California in Santa Barbara, and the MILC collaboration use Blue Waters to study quarks, the subatomic particles that make up the better-known protons and neutrons in the atomic nucleus. Lucas Wagner, professor of physics at the University of Illinois at Urbana-Champaign, experiments with the interactions between electrons in strongly correlated materials that change properties depending on temperature and pressure and under certain conditions become superconductors.

14 Illinois researchers selected for NCSA Fellowships


May 11, 2015

Fourteen faculty members at the University of Illinois at Urbana-Champaign have been selected to receive one-year fellowships that will enable their research teams to pursue collaborative projects with the National Center for Supercomputing Applications. NCSA's fellowship program aims to catalyze and develop long-term collaborations between the center and campus researchers, particularly in the center's six thematic areas of research: Bioinformatics and Health Sciences, Computing and Data Sciences, Culture and Society, Earth and Environment, Materials and Manufacturing, and Physics and Astronomy.
