Intel® MPI Benchmarks 3.2.4
Intel® MPI Benchmarks performs a set of MPI performance measurements for point-to-point and global communication operations for a range of message sizes. The generated benchmark data fully characterizes:
The Intel® MPI Benchmarks package consists of the following components:
IMB-MPI1 - benchmarks for MPI-1 functions
Two components for MPI-2 functionality:
IMB-EXT - one-sided communications benchmarks
IMB-IO - input/output (I/O) benchmarks
Each component corresponds to a separate executable file. You can run all of the supported benchmarks, or specify a single executable file in the command line to get results for a specific subset of benchmarks.
If you do not have the MPI-2 extensions available, you can install and use IMB-MPI1 that uses only standard MPI-1 functions.
This guide is intended for users who want to measure performance of MPI implementations.
