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

Intel Compiler 18.0.3

• The MPICH Library 3.2.1 is installed in directory /usr/nfs/software/icg1/local/mpich-3.2.1-ifort-18.0.3.

• Add the bin subdirectory of the installation directory of MPICH library to your path:

  PATH=/usr/nfs/software/icg1/local/mpich-3.2.1-ifort-18.0.3/bin:$PATH
  export PATH

  Remove serial compiled object files:

  make distclean

  Compile with MPI:

  make useMPI=true progname

  Execute on <n> CPUs:

  mpiexec|mpirun -np <n> <progname>
