IMB-RMA Benchmarks
Intel® MPI Benchmarks provides a set of remote memory access (RMA) benchmarks
that use the passive target communication mode to measure one-sided operations
compliant with the MPI-3 standard.
IMB-RMA Benchmark Modes
When running the IMB-RMA benchmarks, you
can choose between the following modes:
- Standard (default) or multiple mode. You can enable the
multiple mode for all IMB-RMA benchmarks using the –multi
<outflag> command-line parameter. For details, see Running Benchmarks in Multiple Mode.
- Aggregate or non-aggregate mode. For details on these modes,
see the MPI-2 Benchmark Modes chapter.
Some IMB-RMA benchmarks support the non-aggregate
mode only. To determine which benchmarks can run in the aggregate
mode, see Classification
of IMB-RMA Benchmarks.
