       LAM - introduction to Local Area Multicomputer (LAM)


       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 monitoring
       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 (

   Up-to-Date Information
       The  LAM  home  page  can  be  found  on  the  World   Wide   Web   at:   It  should be consulted for the most current
       information about LAM, as well as updates, patches, etc.
