The Intel® MPI Library includes two utilities for improving MPI performance.  The Automatic Tuning utility allows you to tune runtime parameters to match your system and applications.  The Intel® Trace Analyzer and Collector  allows you to instrument and profile your MPI programs to improve parallelism.  I will be presenting a webinar on December 12 discussing how to use these capabilities to improve your MPI application's performance.  For more information, please see http://software.intel.com/node/333491, or you can register right now.
