Intel® MPI Benchmarks User Guide and Methodology Description

# IMB-EXT Benchmarks

This section provides definitions of IMB-EXT benchmarks. The benchmarks can run with varying transfer sizes `X`, in bytes. The timings are averaged over multiple samples. See the Benchmark Methodology section for details. In the definitions below, a single sample with a fixed transfer size `X` is used.

The `Unidir` and `Bidir` benchmarks are exact equivalents of the message passing `PingPong` and `PingPing`, respectively. Their interpretation and output are analogous to their message passing equivalents.
