Performance Analysis and Tuning of LS-DYNA* for Intel® Processor-Based Clusters

Using Intel software tools, including Intel® VTuneTM Performance Analyzer and Intel® Fortran Compiler, we analyze and tune the performance of MPP LS-DYNA* for clusters of Intel processors. We discuss the impact of various performance features of Intel processor-based systems, including vector/streaming instructions, on real LS- DYNA workloads. We compare single-precision performance and measure the impact of various cluster interconnect technologies.
