LS-DYNA® Performance and Scalability On Sun(TM) x64 Systems

This paper describes AMD Opteron -based x64 systems of Sun Microsystems(TM), primarily the server (TM) family. Performance and scalability are shown for the refined Neon standard LS-DYNA benchmark problem – for both gigabit Ethernet and Cisco/Topspin(TM) InfiniBand(TM/SM) interconnects. The Sun Fire(TM) X2100 server, which can be easily installed in a Sun Grid Rack System, is seen to be a very attractive solution based on price- performance considerations. A continued effort on improving LS-DYNA performance on Solaris x64 platform is described. A brief mention is made of future benchmark work planned.
