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.
