Open MPI 1.2.2

Open MPI is a project 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.
Main features:
- Full MPI-2 standards conformance
- Thread safety and concurrency
- Dynamic process spawning
- High performance on all platforms
- Reliable and fast job management
- Network and process fault tolerance
- Support data and network heterogeneity
- Single library supports all networks
- Run-time instrumentation
- Many job schedulers supported
- Many OSs supported (32 and 64 bit)
- Production quality software
- Portable and maintainable
- Tunable by installers and end-users
- Extensive user and installer guides
- Internationalized error messages
- Component-based design, documented APIs
- CPAN-like tool for component management
- Active, responsive mailing list
- Open source license based on the BSD license
The organizations (and newly-combined projects) contributing to Open MPI are Indiana University (LAM/MPI), the University of Tennessee (FT-MPI), and Los Alamos National Laboratory (LA-MPI).
Additional collaborators are at Sandia National Laboratories and the High Performance Computing Center at Stuttgart. These developers bring many years of combined experience to the project.
Enhancements:
- This release fixes handling of $CC when it contains directory names.
- It fixes Fortran 90 status array dimensions, and fixes some compiler warnings.
- pbs-config is used if it can be found, and the rsh launcher is slightly more robust.
- The btl_openib_ib_pkey_value MCA parameter has been added.
