Intel® MPI Benchmarks User Guide and Methodology Description

# 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` 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.
