It is possible to run CLaMS on multi-processor machines using MPI.

Intel Compiler 14.0.3

  • The MPICH Library is installed in directory /usr/nfs/local/local/mpich-intel. Add the bin subdirectory of the installation directory of MPICH library to your path: 

    PATH=/usr/nfs/local/local/mpich-intel/bin:$PATH
export PATH
    Remove serial compiled object files: 
    make distclean
    Compile with MPI: 
    make useMPI=true [useComp=ifc] progname

    Execute on <n> CPUs: 

    mpiexec|mpirun -np <n> <progname>

Portland Compiler 14.6

  • It is necessary to make the path of the MPI libraries (included in the portland compiler suite) public by executing: 
    . /opt/pgi/linux86-64/14.6/mpi.sh
    Remove serial compiled object files: 
    make distclean
    Compile with MPI: 
    make useMPI=true [useComp=pgi] progname

    Execute on <n> CPUs: 

    mpiexec|mpirun -np <n> <progname>
