Intel® MPI Library

Make applications perform better on clusters based on Intel® architecture with multiple fabric flexibility.

  • Now optimized for 2nd Generation Intel® Xeon Phi™ processors and Intel® Omni-Path Architecture
  • Designed and developed for high scalability
  • Supports the latest MPI-3.1 standard
  • MPICH ABI compatibility

Deliver Flexible, Efficient, and Scalable Cluster Messaging

Intel® MPI Library focuses on enabling MPI applications to perform better for clusters based on Intel® architecture—implementing the high-performance MPI-3.1 standard on multiple fabrics. 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.

Intel MPI Library is available as part of Intel® Parallel Studio XE Cluster Edition and as a free stand-alone version. A license purchase includes Priority Support.

Benchmark results were obtained prior to the implementation of recent software patches and firmware updates intended to address exploits referred to as "Spectre" and "Meltdown". Implementation of these updates may make these results inapplicable to your device or system.

Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully evaluating your contemplated purchases, including the performance of that product when combined with other products. For more information, see Performance Benchmark Test Disclosure.

Intel’s compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice. Notice revision #20110804
