The AVIDD-O Cluster

LAM/MPI on the AVIDD-O Cluster

LAM/MPI version 7.1.2 is available on the AVIDD-O Clusters. This version of LAM supports the Myrinet interconnect available on the clusters. You may add LAM/MPI 7.1.2 to your environment with the Softenv key +lam-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.
