Microsoft MPI v7.1 release

Publicado em 7 julho, 2016

Program Manager, Azure

We are happy to announce the release of the newest version of Microsoft MPI (MS-MPI). MS-MPI v7.1 is the successor to the Microsoft MPI v7 redistributable package (released in November 2015). You can download a copy of MS-MPI v7.1 from the Microsoft download center.

MS-MPI v7.1 includes the following notable improvements and fixes to MS-MPI v7:

  • More resilient setup; will not fail when previous uninstallations did not successfully clean up the registry.
  • Bug fixed within MS-MPI v7 that caused jobs to fail when a large number of MPI jobs were executed concurrently on the same set of nodes.
  • MS-MPI v7.1 will automatically fall back to NTLM if Kerberos authentication fails in environment with partial or misconfigured Kerberos support. 
  • mpiexec will support Unicode characters in command line and no longer has a hardcoded limit for command line length.
  • Long path notation (\\?\) is now supported.

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.

To learn more about MS-MPI, see Microsoft MPI on MSDN or in the Windows HPC MPI Forum.
