HPC Benchmarks

Presented below is a performance analysis of FLOW-3D/MP up to 256 cores for some of the typical applications of the software, namely water & environmental, metal casting, microfluidics, and aerospace.

The Performance Metric used for the analysis is defined as the total number of times a given simulation can be run in a single day (24 hours). Larger bars indicate better performance.

The benchmarks were run on nodes with dual Intel Xeon E5-2670 processors (total of 16 cores per node) connected by Infiniband interconnects of up to 40 Gbps.
