ParallelHowTo
It is possible to run CLaMS on multi-processor machines using MPI.
Intel Compiler 17.0.1
The MPICH Library 3.2 is installed in directory /usr/nfs/local/local/mpich-3.2-ifort-17.0.1.
- Add the bin subdirectory of the installation directory of MPICH library to your path:
PATH=/usr/nfs/local/local/mpich-3.2-ifort-17.0.1/bin:$PATH export PATH
Remove serial compiled object files:make distclean
Compile with MPI:make useMPI=true progname
Execute on <n> CPUs:
mpiexec|mpirun -np <n> <progname>
Intel Compiler 14.0.3
The MPICH Library is installed in directory /usr/nfs/local/local/mpich-intel. Add the bin subdirectory of the installation directory of MPICH library to your path:
PATH=/usr/nfs/local/local/mpich-intel/bin:$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:
