any), together. Set the conÞguration’s MpiexecFileName property to

/opt/mpich2/mpich2-1.0.8/bin/mpiexec.

• If you are using a generic scheduler or LSF, modify your parallel wrapper

script to pick up the correct mpiexec. Additionally, there may be a stage

in the wrapper script where the MPI daemons are launched.

The parallel submission 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>".

– DeÞne which mpiexec executable to use for starting workers.

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

manager this means calling "mpdallexit".

For examples of parallel wrapper scripts, see

matlabroot/toolbox/distcomp/examples/integration/; speciÞcally

for an example of Sun Grid Engine, look in the folder sge for

sgeParallelWrapper.sh. Adopt and modify the appropriate script

for your particular cluster usage.
