Intel® MPI Benchmarks 4.0
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.
IMB-NBC - benchmarks for nonblocking collective (NBC) operations.
IMB-RMA - one-sided communications benchmarks. These benchmarks measure the Remote Memory Access (RMA) functionality introduced in the MPI-3 standard.
Each component constitutes 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 or MPI-3 extensions available, you can install and use IMB-MPI1 that uses only standard MPI-1 functions.
