Two U.S. Department of Energy (DOE) IBM Blue Gene/Q systems have won the annual Graph 500 list, announced June 19 at the International Supercomputing Conference, outscoring the closest competitor by a performance factor of seven...

Argonne Scientists Probe the Cosmic Structure of the Dark Universe

on Thu, 08/02/2012 - 02:54

A team of researchers led by Argonne National Laboratory’s Salman Habib and co-PI Katrin Heitmann is carrying out some of the largest high-resolution simulations of the distribution of matter in the Universe. The researchers are resolving galaxy-scale mass concentrations over observational volumes representative of state-of-the-art sky surveys by using Mira, a petascale supercomputer at the Argonne Leadership Computing Facility (ALCF)...
