The following CHPC HPC systems (e1350, Blue Gene/P and Sun Microsytems) use schedulers and resources managers to schedule and run jobs in the systems. Below is the detail information:

e1350 cluster - Moab (Scheduler) and Torque (Resource manager).
Blue Gene/P - Loadleveler (Resource manager).
Sun Microsystems - Moab (Scheduler) and Torque (Resource manager).

Herewith an example script of Moab in e1350 cluster:

#!/bin/sh  
#MSUB -l nodes=8:ppn=8
#MSUB -l walltime=100:00:00
#MSUB -m be
#MSUB -V
#MSUB -o /CHPC/work/username/test/test.out
#MSUB -e /CHPC/work/username/test/test.err
#MSUB -d /CHPC/work/username/test
#MSUB -r y
#MSUB -M email.address
#print the time and date
date
cd /CHPC/work/username/test
nproc=`wc $PBS_NODEFILE| awk '{print $1}'`
/CHPC/usr/local/mpiexec-0.83/bin/mpiexec -n $nproc ./EXECUTABLENAME 

Below is an example script of Moab in Blue Gene/P:

#@ job_type = bluegene
#@ bg_size = 64
#@ class = BGP
#@ input = /dev/null
#@ output = dlpoly.$(jobid).out
#@ error = dlpoly.$(jobid).err
#@ wall_clock_limit = 12:00:00
#@ resources = ConsumableCpus(1)
#@ node_usage = shared
#@ cluster_list = BGP
#@ notification = complete
#@ queue
