LAM/MPI (http://www.lam-mpi.org/) is an open source implementation of the MPI standard; enables clusters and Grid-enabled computers to operate in parallel on a single problem. LAM/MPI offers high performance on multiple platforms, including Linux, Sun Solaris, SGI IRIX, IBM AIX, HP-UX, and Mac OS X, and supports multiple communication interconnects such as shared memory, Gigabit Ethernet, and Myrinet. The most significant change to LAM/MPI for version 7.0 is its new open component architecture. The new modular design provides a flexible "plug-in" framework for selecting and changing run-time components and tuning parameters without the need to recompile user applications. Other significant additions to this release are new systems administration features, which make LAM ideal for use in production environments.
