The AVIDD-B Cluster

LAM/MPI on the AVIDD-B Cluster

LAM/MPI version 7.1.1 is available on the AVIDD-B Cluster. This version of LAM supports the Myrinet interconnect available on the clusters. There are two builds, compiled respectively with the Intel Compilers and GCC:
  • +lam-gm-intel
  • +lam-gm-gcc

To convert your MPICH or MPICH-GM code to use LAM, follow these steps:

  • Recompile with LAM's mpicc (or mpiCC or mpif77)
  • Create a PBS batch file that contains the following lines (minimally):
    lamboot -ssi boot tm
    <your executable and args>
    
  • Submit the job and relax.

The lamboot command will initialize and shutdown the LAM execution environment on the nodes via PBS. See the FAQ at the LAM/MPI website for more information.
