 * Process launcher for the Grid Engine
 *
 * (1) Example of running a batch job under the Grid Engine:
 *
 * Write a script and put in the MPI job
 * @code
 * % cat gridengine.csh 
 * #!/usr/bin/csh
 * 
 * # you can optionally set PATH and LD_LIBRARY_PATH instead of setting prefix
 * set prefix=/path_to/open-mpi-build
 *
 * /path_to/mpirun -np 4 -prefix $prefix ./connectivity -v
 * @endcode
 *
 * Source the grid engine environment:
 * @code
 * % source /opt/n1ge/default/common/settings.csh
 * @endcode
 *
 * Submit the job with 4 PE slots
 * under a predefined Parallel Environment 'orte':
 * @code
 * % qsub -pe orte 4 gridengine.csh 
 * your job 305 ("gridengine.csh") has been submitted
 * @endcode
 *
 * Getting the output:
 * @code
 * % more gridengine.csh.o305
 * Warning: no access to tty (Bad file number).
 * Thus no job control in this shell.

 * (2) Example of running an interactive job under the Grid Engine:
 *
 * Source the grid engine environment:
 * @code
 * % source /opt/n1ge/default/common/settings.csh
 * @endcode
 *
 * Start an interactive job with 4 slots
 * under a predefined Parallel Environment 'orte':
 * @code
 * % qsh -pe orte 4
 * waiting for interactive job to be scheduled ... 
 * Your interactive job 324 has been successfully scheduled.
 * @endcode
 *
 * Run the MPI job. You may need to set PATH and LD_LIBRARY_PATH or -prefix
 * @code
 * % /path_to/mpirun -np 4 hostname
 * host-5
 * host-5
 * host-4
 * host-4
 * @endcode
