LS-DYNA® Performance on 64-Bit Intel® Xeon® Processor-Based Clusters

Benchmark performance of a cluster based on the newly introduced 64-Bit Intel® Xeon® Procesessor-based clusters is presented. Car2car and 3cars benchmarks from topcrunch.org are evaluated, using OpenIB based interconnects. Effect of shared memory options under Intel® MPI is evaluated. Improvement from optimizing 3cars P-file decomposition is demonstrated. Intel® Cluster Tools profiler is discussed.
