#
# Purpose: Running this script launches multiple serial jobs in batch.
# Usage: scc1% submitmjobs ntasks batch_script "SGE options"
# Runtime input parameters to submitmjobs:
#   ntasks -- the number of tasks submitted to batch queue
#   batch_script -- such as run_matlab_job, for MATLAB apps
#   The OPTIONAL input must be valid SGE batch parameters.
# Example:
# scc1% submitmjobs 4 run_matlab_job "-l h_rt=09:00:00"
#
# In the above, running submitmjobs launches 4  run_matlab_job with a
# wallclock limit of 9 hours for each of 4 tasks. The optional third
# input specifies runtime limit. Without it, the default wallclock limit
# is 2 hours for each task. Each of the 4 tasks is assigned a unique
# index, task, ranged between 1 to 4. You can use
# task's value to determine what data or action to take.
#
# The Sun Grid Engine batch preserves the current dir in batch.
# A different dir may also be used
# cd my_dir
