NAME
LAM - introduction to Local Area Multicomputer (LAM) DESCRIPTION
LAM is an MPI programming environment and development system for a message-passing parallel machine constituted with heterogeneous UNIX computers on a network. With LAM, a dedicated cluster or an existing network computing infrastructure can act as one parallel computer solving one compute-intensive problem. LAM emphasizes productivity in the application development cycle with extensive control and moni- toring functionality. The user can easily debug the common errors in parallel programming and is well equipped to diagnose more difficult problems. LAM features a full implementation of the MPI communication standard, with the exception that the MPI_CANCEL function will not properly cancel messages that have been sent. User Information Users are strongly encouraged to read the LAM/MPI User's Guide that is included with the LAM/MPI distribution, and is provided on the main LAM/MPI web site (http://www.lam-mpi.org/). Up-to-Date Information The LAM home page can be found on the World Wide Web at: http://www.lam-mpi.org/. It should be consulted for the most current information about LAM, as well as updates, patches, etc. SEE ALSO
