NSF awards time on Blue Waters to seven new projects


Oct 1, 2014

The National Science Foundation (NSF) has awarded 14 new allocations on the Blue Waters petascale supercomputer at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. Seven of the awards are for new projects.

Blue Waters Symposium a success


May 28, 2014

The symposium, held May 13-15 in Champaign, Ill., gathered many of the country’s leading supercomputer users to share what they have learned using Blue Waters and discuss the future of supercomputing. On May 13, 2014, Blue Waters supercomputer users and many of the NCSA staff who support their work converged in Champaign, Ill., for the second annual Blue Waters Symposium. The ensuing three days were filled with what many of them would later refer to as a wonderful variety of science talks and opportunities for networking and collaboration.

4 applications sustain 1 petaflop on Blue Waters


Jan 29, 2013

Four large-scale science applications (VPIC, PPM, QMCPACK and SPECFEM3DGLOBE) have sustained performance of 1 petaflop or more on the Blue Waters supercomputer, and the Weather Research & Forecasting (WRF) run on Blue Waters is the largest WRF simulation ever documented. These applications are part of the NCSA Blue Waters Sustained Petascale Performance (SPP) suite and represent valid scientific workloads. VPIC VPIC integrates the relativistic Maxwell-Boltzmann system in a linear background medium for multiple particle species, in time with an explicit-implicit mixture of velocity Verlet, leapfrog, Boris rotation and exponential differencing based on a reversible phase-space volume conserving second order Trotter factorization. The Petascale Computing Resource Allocation (PRAC) team led by Homayoun Karimabadi (University of California-San Diego) is using VPIC in for kinetic simulations of magnetic reconnection of high temperature plasmas (H+ and e-).

4 more research groups using Blue Waters Early Science System


May 21, 2012

Four additional research teams have begun using the first phase of the Blue Waters sustained-petascale supercomputer to tackle challenging problems in science and engineering. They join six research groups that began using the system in March. The Blue Waters Early Science System, which is made up of 48 Cray XE6 cabinets, represents about 15 percent of the total Blue Waters computational system and is currently the most powerful computing resource available through the National Science Foundation.

When tornadoes attack


Apr 6, 2010

In many ways, tornadoes remain a mystery. While their powerful winds can leave broad swaths of devastation—damaged and destroyed homes and businesses, injuries and fatalities—twisters are a challenge for atmospheric scientists to study. It's difficult (not to mention hazardous) to be in the exact right place at the precisely the right time to see one in action, and models that capture all of the critical small-scale details within a dynamic storm system are computationally demanding. That's where the sustained-petaflop Blue Waters supercomputer comes into the picture. The University of Illinois' Bob Wilhelmson is the principal investigator for a Petascale Computing Resource Allocation project.

Astrophysicists, cosmologists to tap power of Blue Waters


Mar 18, 2010

Blue Waters is expected to be the most powerful supercomputer in the world for open scientific research when it comes online at Illinois in 2011. Scientists and engineers who are eager to tap this sustained-petaflop powerhouse for breakthrough research are already working closely with the Blue Waters project team to prepare their codes. The National Science Foundation provides Petascale Computing Resource Allocations (PRAC awards) to support these collaborations, which include help porting and re-engineering existing applications and in some cases building entirely new applications based on new programming models. Current PRAC projects—18 representing about 30 institutions—represent a wide range of scientific disciplines: biology and health, weather and climate, earthquakes and geophysics, and cosmology and our universe.
