A Performance Study of LS-DYNA on Vehicle Crash Simulation

For computer companies to design cost-effective machines for LSTC to optimize the software and for the LS-DYNA user to make an intelligent choice of machines, various factors that affect LS-DYNA’s performance must be investigated and understood. Therefore, we have embarked such an investigation with machines from both Hewlett- Packard and SGI. Many results are reported here. The factors considered include the following: memory systems, SMP vs. MPP LS-DYNA, single vs. double precision, cluster vs. ccNUMA configuration.
