Its uses include understanding just how explosives ignite. http://ascr-discovery.science.doe.gov/kernels/henshaw1.shtml Kernels http://ascr-discovery.science.doe.gov/kernels/henshaw1.shtml Tue, 31 Jul 2007 08:00:00 -0400 A computer simulation will show how new, efficient nuclear power plants can keep their cool. The project will use a grant of 1 million processor hours from the Department of Energy’s INCITE program. http://ascr-discovery.science.doe.gov/bigiron/fischer1.shtml Big Iron http://ascr-discovery.science.doe.gov/bigiron/fischer1.shtml Mon, 13 Aug 2007 08:00:00 -0400 A UCLA mathematician is creating faster, more accurate simulations of plasmas, the ionized gas clouds central to the power of stars - and of nuclear fusion. His models span huge scales of space and time. http://ascr-discovery.science.doe.gov/universities/caflisch1.shtml At the Universities http://ascr-discovery.science.doe.gov/universities/caflisch1.shtml Tue, 31 Jul 2007 08:00:00 -0400 How the folklore of computer programming affects efficiency is a University of Maryland professor’s target. He tests those traditions to fined more efficient code-writing techniques. http://ascr-discovery.science.doe.gov/universities/basili1.shtml At the Universities http://ascr-discovery.science.doe.gov/universities/basili1.shtml Mon, 18 Jun 2007 08:00:00 -0400 A bicoastal partnership helped make a fusion reactor refueling simulation run hundreds of times faster than before. The results may answer questions about what refueling scheme is best. http://ascr-discovery.science.doe.gov/synchronized/sam_col1.shtml Synchronized http://ascr-discovery.science.doe.gov/synchronized/sam_col1.shtml Mon, 4 Jun 2007 08:00:00 -0500 The Department of Energy’s high-performance computing centers have their roots in energy research, but have branched out to everything from bacteria to bosons. http://ascr-discovery.science.doe.gov/genealogy/mfecc1.shtml Genealogy http://ascr-discovery.science.doe.gov/genealogy/mfecc1.shtml Tue, 31 Jul 2007 08:00:00 -0400 An Oak Ridge National Laboratory researcher’s simulations of shock waves and detonations could provide insights into preventing pipeline explosions and other incidents. http://ascr-discovery.science.doe.gov/newfaces/deiterding1.shtml New Faces http://ascr-discovery.science.doe.gov/newfaces/deiterding1.shtml Mon, 5 Feb 2008 08:00:00 -0400
