NCSA Grants $2.6M in Blue Waters Awards to Illinois Researchers


Jul 6, 2017

The National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign has awarded 3,697,000 node hours (NH) of time on the Blue Waters supercomputer to Illinois researchers from Spring 2017 proposal submissions. The combined value of these awards is over $2.6 million dollars, and through the life of the Blue Waters program, NCSA has awarded over 43 million node hours to UI researchers—a value of nearly $27 million. Some of the time allocated for Blue Waters will go to projects that focus on HIV research, Laser Interferometer Gravitational-Wave Observatory (LIGO) simulations, genomics and global warming research.

Leggo my LIGO


Mar 2, 2016

After LIGO detected gravitational waves a few months ago (detected in September 2015 but announced in February 2016), LIGO and gravitational waves became almost household words. However, did you know that the revolutionary observations couldn’t have been made without the help of the U of I? ... In recognition of his work in getting NSF funding to build these supercomputers and the benefits thereof, Professor Smarr was awarded the Golden Goose award by the Association of American Universities back in February of 2014. The award is presented once a year to honor federally-funded research which has lead to major breakthroughs in science. Any researcher who has produced something within the previous 60 years is eligible. The fact that Professor Smarr received this award is a testament to the importance of the NCSA and its capabilities.

Gravitational waves detected 100 years after Einstein’s prediction


Feb 11, 2016

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos. ... The gravitational waves were detected on Sept. 14, 2015, at 5:51 a.m. Eastern Daylight Time (9:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, La., and Hanford, Wash. The LIGO Observatories are funded by the National Science Foundation, and were conceived, built, and are operated by Caltech and Massachusetts Institute of Technology. The discovery, accepted for publication in the journal Physical Review Letters, was made by the LIGO Scientific Collaboration (which includes the GEO Collaboration and the Australian Consortium for Interferometric Gravitational Astronomy) and the Virgo Collaboration using data from the two LIGO detectors.

Discovery confirms Einstein prediction; NCSA played role


Feb 11, 2016

A billion light years from Earth, two dense objects known as black holes collide at enormous speed, sending giant ripples through the fabric of space-time. Albert Einstein predicted such an event a century ago as part of his theory of relativity, and scientists have been searching for those ripples, known as gravitational waves, ever since. The announcement of their discovery sent waves of excitement around the globe Thursday, including at the National Center for Supercomputing Applications in Urbana, created 30 years ago to help scientists solve enormous computational puzzles like this one.

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.”

22 Illinois projects receive time on Blue Waters


Jun 11, 2013

The University of Illinois at Urbana-Champaign has awarded access to the Blue Waters supercomputer—which is capable of performing quadrillions of calculations every second and of working with quadrillions of bytes of data—to 22 campus research teams from a wide range of disciplines. The computing and data capabilities of Blue Waters, which is operated by the National Center for Supercomputing Applications (NCSA), will assist researchers in their work on understanding DNA, developing biofuels, simulating climate, and more.
