Recent Developments of LS-DYNA Performance Optimization

Youn-Seo Roh and Henry Fong Sun Microsystems, Inc. A recent effort of optimizing the performance of LS-DYNA running on SPARC(R)-SolarisTM servers is described. With new releases of compilers, generated executables benefit from the additional performance of latest UltraSPARC(R) CPU's for SMP servers. Also, new release of Sun HPC ClusterToolsTM cluster environment includes tools that facilitates tuning of LS-DYNA-MPP executables and the MPI environment. A collection of development tools targeted for SPARC performance improvement results in faster simulations, fully benefiting continuously updated hardware performance. Those developments are exhibited with customer benchmark examples. With Sun ONE Grid Engine products, more efficient simulation environment is viable for LS-DYNA simulation.
