any), together. Set the configuration’s MpiexecFil eNam e property to

/opt/mpich2/mpich2-1.4.1p1/bin/mpiexec.

• If you are using a third-party scheduler (either fully supported or via the

generic interface), modify your communicating job wrapper script to

pick up the correct

mpiexec. Additionally, there might be a stage in the

wrapper script where the MPI process manager daemons are launched.

The communicating job wrapper script must:

– Determine which nodes are allocated by the scheduler.

– Start required daemon processes. For example, for the MPD process

manager this means calling

"mpdboot -f <nodefile>".

– Define which mpiex ec executable to use for starting workers.

– Stop the daemon processes. For example, for the MPD process

manager this means calling

"mpdallexit".

For examples of com municating job wrapper scripts, see the subfolders of

matlabroot/toolbox/distcomp/examples/integration/; specifically,

for an example for Sun Grid Engine, look in the subfolder

sge/shared

for communi cati ngJobWrapper.sh. Wrapper scripts are available for

various schedulers and file sharing configurations. Adopt and modify

the appropriate script for your particular cluster usage.
