Ohio Supercomputer Center has released LAM 6.0, a major upgrade of its MPI implementation for UNIX-based clusters. The software is freely available from http://www.osc.edu/lam.html.
Among the new features in LAM 6.0 are an early implementation of MPI, process spawning, dynamic processor resources and fault tolerance.
LAM 6.0 runs out-of-the-box on IP networks connecting any of the major vendors' workstations in any combination. LINUX is also supported.
