The History of LAM/MPI

LAM was originally developed at the Ohio Supercomputing Center. Since then, the original members of the LAM Team moved to other jobs, and LAM became an orphaned project. The Laboratory for Scientific Computing (LSC) at the University of Notre Dame, headed by Dr. Andrew Lumsdaine, adopted LAM and hosted it in its servers.

Soon after LAM was adopted by Notre Dame, version 6.2b was released, which contained some unreleased work from the original LAM Team, and a few contributions from the new Notre Dame LAM Team. Version 6.2b proved to be stable and robust in a variety of unix environments.

Development on LAM has continued by the Notre Dame LAM Team; the release of 6.3 included several new debugging features for user MPI programs, new environmental controls, and a variety of bug fixes from the original 6.2b release. Debugging parallel programs, which has been problematic in the past, is now much easier due to relaxations in LAM's process model.

In the fall of 2001, Dr. Lumsdaine and the LSC moved to Indiana University. The LSC was renamed the Open Systems Laboratory (OSL) and all LSC projects, including LAM, moved from Notre Dame to Indiana with Dr. Lumsdaine.

LAM/MPI is intended to be an open implementation of MPI. Since version 6.5.5, LAM/MPI has been licensed under the familiar revised BSD license.

LAM 7.1.4 is now the officially supported version of LAM. The use of prior versions are (strongly) discouraged, and are not likely to be supported.
