9 LAM is an MPI programming environment and development system for a mes‐
10 sage-passing parallel machine constituted with heterogeneous UNIX com‐
11 puters on a network. With LAM, a dedicated cluster or an existing net‐
12 work computing infrastructure can act as one parallel computer solving
13 one compute-intensive problem. LAM emphasizes productivity in the
14 application development cycle with extensive control and monitoring
15 functionality. The user can easily debug the common errors in parallel
16 programming and is well equipped to diagnose more difficult problems.
17
18 LAM features a full implementation of the MPI communication standard,
19 with the exception that the MPI_CANCEL function will not properly can‐
20 cel messages that have been sent.

22 User Information
23 Users are strongly encouraged to read the LAM/MPI User's Guide that is
24 included with the LAM/MPI distribution, and is provided on the main
25 LAM/MPI web site (http://www.lam-mpi.org/).
