Fedora Core 4 7.1.1-7 Update: LAM MPI Programming Enhancement

LAM (Local Area Multicomputer) is an Message-Passing Interface (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 one parallel

computer to solve one problem. LAM/MPI is considered to be "cluster

friendly" because 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 (different RPMs

are supplied for this -- see the main LAM website at

for details).<

LAM features a full implementation of MPI version 1 (with the

exception that LAM does not support cancelling of sends), and much of

version 2. Compliant applications are source code portable between LAM

and any other implementation of MPI. In addition to meeting the

standard, LAM/MPI offers extensive monitoring capabilities to support

debugging. Monitoring happens on two levels: On one level, LAM/MPI has

the hooks to allow a snapshot of a process and message status to be

taken at any time during an application run. The status includes all

aspects of synchronization plus datatype map/signature, communicator

group membership and message contents (see the XMPI application on the

main LAM website). On the second level, the MPI library can produce a

cumulative record of communication, which can be visualized either at

runtime or post-mortem.
