Description :
Open MPI is an open source, freely available implementation of both the
MPI-1 and MPI-2 standards, combining technologies and resources from
several other projects (FT-MPI, LA-MPI, LAM/MPI, and PACX-MPI) in
order to build the best MPI library available.  A completely new MPI-2
compliant implementation, Open MPI offers advantages for system and
software vendors, application developers, and computer science
researchers. For more information, see http://www.open-mpi.org/ .

Update Information:

v1.8.3 is a bug fix release.  All users are encouraged to upgrade to v1.8.3 when possible. 

Here is a list of changes in v1.8.3 as compared to v1.8.2:

- Fixed application abort bug to ensure that MPI_Abort exits appropriately and returns the provided exit status
- Fixed some alignment (not all) issues identified by Clang
- Allow CUDA-aware to work with nonblocking collectives. Forces packing to happen when using GPU buffers.
- Fixed configure test issue with Intel 2015 Fortran compiler
- Fixed some PGI-related errors
- Provide better help message when encountering a firewall
- Fixed MCA parameter quoting to protect multi-word params and params that contain special characters
- Improved the bind-to help message to clarify the defaults
- Add new MPI-3.1 tools interface
- Several performance optimizations and memory leak cleanups
- Turn off the coll/ml plugin unless specifically requested as it remains in an experimental state
- Fix LSF support by adding required libraries for the latest LSF releases.  Thanks to Joshua Randal for supplying the initial patches.
