MPI package for Octave ====================== Examples of Octave scripts using MPI are located under the examples/ subdirectory. You can test your MPI installation by running the helloworld.m script from within that examples/ directory. Note that, because of a dynamic linking issue with OpenMPI, it is necessary to preload libmpi.so before running Octave on each node. This can be achieved with something like: mpirun -x LD_PRELOAD=libmpi.so -np $NUMBER_OF_MPI_NODES $OTHER_MPI_OPTIONS octave -q --eval 'helloworld ()' More technical details about the LD_PRELOAD issue can be found in the following thread: http://www.open-mpi.org/community/lists/users/2010/04/12677.php -- Sébastien Villemot , Mon, 17 Mar 2014 18:48:46 +0100
