Location of MPI implementation
[primaryLib,extras] = mpiLibConf
MPI implementation library used by a communicating job.
Cell array of other required library names.
[primaryLib,extras] = mpiLibConf returns
the MPI implementation library to be used by a communicating job.
primaryLib is the name of the shared library file containing
the MPI entry points.
extras is a cell array of other library
names required by the MPI library.
To supply an alternative MPI implementation, create a file named
mpiLibConf.m, and place it on the MATLAB® path. The recommended location is
mpiLibConf.m file must be higher on the cluster workers'
mpiLibConf.m as a file dependency for this purpose does
not work.) After your
mpiLibConf.m file is in place, update the
toolbox path caching with the following command in MATLAB:
mpiLibConf function to view the current MPI
Under all circumstances, the MPI library must support all MPI-1 functions.
Additionally, the MPI library must support null arguments to
MPI_Init as defined in section 4.2 of the MPI-2 standard. The
library must also use an
mpi.h header file that is fully
compatible with MPICH2.
When used with the MATLAB Job Scheduler or the local cluster, the MPI library must support the following additional MPI-2 functions:
When used with any third-party scheduler, it is important to launch the workers using the version of mpiexec corresponding to the MPI library being used. Also, you might need to launch the corresponding process management daemons on the cluster before invoking mpiexec.
