Making applications perform better on Intel® architecture-based clusters with multiple fabric flexibility

  • Scalability verified up to 340k processes
  • Supports the latest MPI-3 standard
  • MPICH ABI compatibility

Deliver Flexible, Efficient, and Scalable Cluster Messaging

Intel® MPI Library 5.1 focuses on making applications perform better on Intel® architecture-based clusters—implementing the high performance Message Passing Interface Version 3.0 specification on multiple fabrics. It enables you to quickly deliver maximum end user performance even if you change or upgrade to new interconnects, without requiring changes to the software or operating environment.

Use this high performance MPI message library to develop applications that can run on multiple cluster interconnects chosen by the user at runtime. Benefit from a free runtime environment kit for products developed with Intel MPI Library. Get excellent performance for enterprise, divisional, departmental, workgroup, and personal high performance computing.
