LAM (Local Area Multicomputer) is an MPI programming environment and
development system for heterogeneous computers on a network. With LAM,
a dedicated cluster or an existing network computing infrastructure can
act as one parallel computer solving one problem.

LAM features extensive debugging support in the application development
cycle and peak performance for production applications. LAM also
features a full implementation of the MPI (Message Passing Interface)
communication standard. The documentation is installed in
/usr/share/doc/packages/lam/.
