Summary : LAM/MPI (Local Area Multicomputer) programming runtime environment
|
Description :
LAM (Local Area Multicomputer) is an MPI programming environment and development system for heterogeneous computers on a network. With LAM/MPI, a dedicated cluster or an existing network computing infrastructure can act as a single parallel computer. LAM/MPI is considered to be \"cluster friendly\", in that it offers daemon-based process startup/control as well as fast client-to-client message passing protocols. LAM/MPI can use TCP/IP and/or shared memory for message passing (currently, different RPMs are supplied for this -- see the main LAM web site for details).
LAM features a full implementation of MPI-1 (with the exception that LAM does not support cancelling of sends), and much of MPI-2. Compliant applications are source code portable between LAM/MPI and any other implementation of MPI. In addition to providing a high-quality implementation of the MPI standard, LAM/MPI offers extensive monitoring capabilities to support debugging. Monitoring happens on two levels. First, LAM/MPI has the hooks to allow a snapshot of process and message status to be taken at any time during an application run. This snapshot includes all aspects of synchronization plus datatype maps/signatures, communicator group membership, and message contents (see the XMPI application on the main LAM web site). On the second level, the MPI library is instrumented to produce a cummulative record of communication, which can be visualized either at runtime or post-mortem.
