Special report: Graphics processing units speed results in extreme-scale supercomputers

DOE/Oak Ridge National Laboratory

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.
