LAM runtime environment for executing parallel programs


LAM (Local Area Multicomputer) is an open source implementation of the Message Passing Interface (MPI) standard.

Some enhancements in LAM 6.3 are:
 o Added the MPI-2 C++ bindings package (chapter 10 from the MPI-2
     standard) from the Laboratory for Scientific Computing at the
     University of Notre Dame.
 o Added ROMIO MPI I/O package (chapter 9 from the MPI-2 standard)
     from the Argonne National Laboratory.
 o Pseudo-tty support for remote IO (e.g., line buffered output).
 o Ability to pass environment variables through mpirun.
 o Ability to mpirun shell scripts/debuggers/etc. (that eventually
     run LAM/MPI programs).
 o Ability to execute non-MPI programs across the multicomputer.
 o Added configurable ability to zero-fill internal LAM buffers
     before they are used (for development tools such as Purify).
 o Greatly expanded error messages; provided for customizable
     local help files.
 o Expanded and updated documentation.
 o Various bug fixes and minor enhancements.
