Intel MPI Library 4.1 focuses on making applications perform better on IA-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.
