Intel MPI Benchmark

The idea of IMB is to provide a concise set of elementary MPI benchmark kernels. With one executable, all of the supported benchmarks, or a subset specified by the command line, can be run. The rules, such as time measurement including a repetitive call of the kernels for better clock synchronization, message lengths, selection of communicators to run a particular benchmark inside the group of all started processes are program parameters.
