LAM(7) LAM OVERVIEW LAM(7)
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.
