What’s New
This section provides changes for the Intel(R) MPI Benchmarks as compared to the previous versions of this product.
Intel(R) MPI Benchmarks 2019 Update 7
No changes except bug fixes.
Intel(R) MPI Benchmarks 2019 Update 6
New IMB-P2P Stencil2D and Stencil3D benchmarks.
Intel(R) MPI Benchmarks 2019 Update 5
Added Microsoft Visual Studio(R) projects for IMB-P2P.
Intel(R) MPI Benchmarks 2019 Update 4
No changes except bug fixes.
Intel(R) MPI Benchmarks 2019 Update 3
Added the warm_up option, which enables additional cycles before running benchmark (for all sizes).
Intel(R) MPI Benchmarks 2019 Update 2
New IMB-P2P benchmarks. IMB-P2P is a shared memory transport oriented benchmarks for MPI-1 point-to-point communications. See IMB-P2P Benchmarks for details.
Intel(R) MPI Benchmarks 2019 Update 1
Added new options for MPI-1. See Command-Line Control for details.
Iteration policy can no longer be set with the -iter option. Use -iter_policy instead.
Intel(R) MPI Benchmarks 2019
New IMB-MT benchmarks. The benchmarks implement the multithreaded version of some of the IMB-MPI1 benchmarks using the OpenMP* paradigm. See Multithreaded MPI-1 Benchmarks for details.
Added a new benchmark. See Reduce_scatter_block for details.
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. See Command-Line Control for details.
Added new options for MPI-1. See Command-Line Control for details.
Iteration policy can no longer be set with the -iter option. Use -iter_policy instead.
Intel(R) MPI Benchmarks 2018 Update 1
Support for the Microsoft* Visual Studio 2017. Microsoft Visual Studio 2012 support is removed.
Intel(R) MPI Benchmarks 2018
Extended description for the -multi and -map options. See Command-Line Control.
Removed support of the Intel(R) Xeon Phi* coprocessor (formerly code named Knights Corner).
Intel(R) MPI Benchmarks 2017 Update 1
This release includes the following updates as compared to the Intel(R) MPI Benchmarks 2017:
Added a new option -imb_barrier.
The PingPong and PingPing benchmarks are now equivalent to PingPongSpecificSource and PingPingSpecificSource, respectively. Their old behavior (with MPI_ANY_SOURCE) is available in PingPongAnySource and PingPingAnySource.
Intel(R) MPI Benchmarks 2017
This release includes the following updates as compared to the Intel(R) MPI Benchmarks 4.1 Update 1:
Changed default values for the -sync and -root_shift options. See Command-Line Control.

This release includes the following updates as compared to the Intel(R) MPI Benchmarks 4.1:
Minor improvements and bug fixes.
Intel(R) MPI Benchmarks 4.1
This release includes the following updates as compared to the Intel(R) MPI Benchmarks 4.0:
Introduced new benchmarks: Uniband and Biband. See Parallel Transfer Benchmarks.
Introduced new options: -sync and -root_shift. See Command-Line Control.
Intel(R) MPI Benchmarks 4.0
This release includes the following updates as compared to the Intel(R) MPI Benchmarks 3.2.4:
Introduced new components IMB-NBC and IMB-RMA that conform to the MPI-3.0 standard.
Introduced a new feature to set the appropriate policy for automatic calculation of iterations. You can set the policy using the -iter and -iter_policy options.
