Intel® MPI Library

Boost application performance on Intel® architecture-based clusters with this message-passing interface library

Intel® MPI Library 3.2 focuses on making applications perform better on Intel architecture-based clusters—implementing the high performance MPI-2 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 major changes to the software or operating environment. Use this high-performance message-passing interface library to develop applications that can run on multiple cluster fabric interconnects chosen by the user at runtime. Intel also provides a free runtime environment kit for products developed with the Intel MPI library. Get best-in-class performance for enterprise, divisional, departmental, and workgroup high performance computing.

Intel® MPI Library 4.0 Beta provides new levels of performance and flexibility for applications that execute on clusters of Intel platforms. The library achieves these advantages by improved interconnect support, faster on-node messaging and an enhanced tuning capability that adjusts to the cluster architecture and application structure. In addition, the library maintains compatibility with previous Intel MPI Library 3.x versions while providing an enhanced architecture that will enable interconnect vendors and Intel processors to better expose their future maximum performance and functionality.
