LAM/MPI 7.1.3

LAM/MPI is an implementation of the Message Passing Interface (MPI) parallel standard that is especially friendly to clusters. It includes a persistent runtime environment for parallel programs, support for all of MPI-1, and a good chunk of MPI-2, such as all of the dynamic functions, C++ bindings, one-way communication and MPI-IO.
LAM/MPI is now in a maintenance mode. Bug fixes and critical patches are still being applied, but little real "new" work is happening in LAM/MPI. This is a direct result of the LAM/MPI Team spending the vast majority of their time working on our next-generation MPI implementation -- Open MPI.
Although LAM is not going to go away any time soon (we certainly would not abondon our user base!) -- the web pages, user lists, and all the other resources will continue to be available indefinitely -- we would encourage all users to try migrating to Open MPI. Since its an MPI implementation, you should be able to simply recompile and re-link your applications to Open MPI -- they should "just work." Open MPI contains many features and performance enhancements that are not available in LAM/MPI.
Enhancements:
- Man page cleanups.
- Fixes for when tkill is not in the default location.
- A fix for hangs in 64-bit builds on Mac OS X systems.
- Localhost searches have changed to 127.0.0.0/8.
- Support for Fortran types MPI_REAL{4,8,16} for predefined floating point operations.
- A compile error in "ib" RPI, a problem with MPI_COMM_ACCEPT on Fedora Core 4, name clashes with FreeBSD symbols, Cygwin installation symlinks, an issue with hostfile comments, and Totalview shared object support on OS X have been fixed.
- The restart logic in the "self" CR module has been cleaned up.
- A lot of checkpoint/restart documentation has been added.
