Intel(R) MPI Benchmarks 2019 Update 1

What's New

• Added the Reduce_scatter_block benchmark for IMB-MPI1.
• Added the aggregate_mode option that specifies the mode for IMB-IO, IMB-EXT and IMB-RMA.
• Added the alignment option that controls buffer alignment.
• Updated the following options:
  • -data_type now supports double.
  • -red_data_type now supports double.

Intel(R) MPI Benchmarks 2019

What's New:

• New IMB-MT benchmarks. The benchmarks implement the multithreaded version of some of the IMB-MPI1 benchmarks using the OpenMP* paradigm.
• New benchmarks infrastructure implemented in C++. The IMB-MPI1, IMB-RMA and IMB-MT implementation is now based on the new C++ infrastructure (IMB-NBC, IMB-EXT and IMB-IO still use the legacy one). The legacy infrastructure is preserved in src_c subdirectory.
• Changes in syntax for the -include and -exclude options. Benchmarks to include and exclude now must be separated by a comma rather than a space. Benchmarks to launch can be separated by a comma or a space.
• Iteration policy can no longer be set with the -iter option. Use -iter_policy instead.
• Added a new option -noheader for IMB-MT to disable printing of benchmark headers.
• Added a new benchmark BarrierMT for IMB-MT.
