Special report: Graphics processing units speed results in extreme-scale supercomputers
Can scientists and engineers benefit from extreme-scale supercomputers that use application-code accelerators called GPUs (graphics processing units)? Comparing GPU accelerators with today's fastest central processing units (CPUs), early results from diverse areas of research show 1.5- to 3-fold speedups for most codes. That acceleration means increased realism of simulations and decreased time to results. A special report details these findings.

Supernovas explode in 3-D detail at Oak Ridge National Laboratory
Understanding a Type Ia supernova -- an exploding white dwarf star -- requires supercomputers. A team of astrophysicists and computational scientists is using the power of Oak Ridge National Laboratory's Jaguar to virtually blow up these white dwarfs. In the process the researchers are revealing the secrets of the biggest thermonuclear explosions in the universe and finding the answers needed to measure the size of the universe.
