One Library with Multiple Fabric Support

Intel® MPI Library is a multifabric message-passing library that implements the open-source MPICH specification. Use the library to create, maintain, and test advanced, complex applications that perform better on high-performance computing (HPC) clusters based on Intel® processors.

  • Develop applications that can run on multiple cluster interconnects chosen by the user at run time.
  • Quickly deliver maximum end-user performance without having to change the software or operating environment.
  • Achieve the best latency, bandwidth, and scalability through automatic tuning for the latest Intel® platforms.
  • Reduce the time to market by linking to one library and deploying on the latest optimized fabrics.
