We are happy to announce the release of the newest version of Microsoft MPI (MS-MPI). MS-MPI v8 is the successor to the Microsoft MPI v7.1 redistributable package (released in June 2016). You can download a copy of MS-MPI v8 from the Microsoft download center.

MS-MPI v8 includes the following new features, improvements, and fixes.

  • Complete support for all MPI-3 non-blocking collectives.
  • Support for MPI_Reduce_scatter_block.
  • Performance improvement for MPI_Alltoallv and MPI_Alltoallw.
  • A bug in MS-MPI v7 that causes missing information in the event source for the MSMPI Launch Service.
  • A bug in MS-MPI v7.1 that causes a hang in MSMPI Launch Service.
  • A bug in MS-MPI v7 that can results in a bad port string returned from MPI_Open_port.

The MS-MPI v8 SDK is also available on nuget.

Note: The SDK components for MS-MPI (headers and libraries) ship separately from the redistributable package binary files. However, it is available from the same download page with the redistributable package.
