SPH Performance Enhancement in LS-DYNA
The Smoothed Particle Hydrodynamic (SPH) method had been implemented in LS-DYNA for some time. However, SPH had not been used extensively; therefore, performance issues were never highlighted and never addressed. Recent efforts to run SPH on NEC SX systems revealed substantial performance problems. NEC, Yokohama Rubber Corporation and LSTC collaborated to enhance the performance of SPH. As a result, the performance of SPH function in LS-DYNA has been improved on NEC SX-6 vector-parallel supercomputer by a factor of four. This article provides some background information about the code tuning effort, the SX series vector-parallel supercomputers, and the performance improvement achieved
