Intel(R) MPI Library3.2 update 1 focuses on making applications perform better on Intel(R) 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.
What's new in this version:
Version 4.0 includes new architecture for better performance and higher scalability and updates MPI performance tuner to extract the last ounce of performance out of your installation.
