Microsoft MPI (MS-MPI) is a Microsoft implementation of the Message Passing Interface standard for developing and running parallel applications on the Windows platform.
MS-MPI offers several benefits:
- Ease of porting existing code that uses MPICH.
- Security based on Active Directory Domain Services.
- High performance on the Windows operating system.
- Binary compatibility across different types of interconnectivity options.
The following are current downloads for MS-MPI:
- MS-MPI v10.0 (new!) - see Release notes
- The MS-MPI SDK is also available on Nuget.
Earlier versions of MS-MPI are available from the Microsoft Download Center.
