Case Studies

Case Study1

N-body Astrophysical GPU Application GPU cluster (Dirac, NERSC) was used for benchmarking and testing of a parallel N-body Hermite Integration code for GPUs called phi-GPU. Results show a speedup of ~ 50% by using Fermi C2050 cards (Dirac, NERSC), in comparison to Tesla C1060 cards (Laohu cluster, NAOC, Beijing). A speed up for a 6th order Hermite integration scheme, in comparison to the 4th Hermite scheme has been also achieved. Benchmarks and tests of a standard N-body… Read More »
