# a sample job submission script to submit an MPI job to the broadwl partition on Midway2

# set the job name to hello-mpi
#SBATCH --job-name=hello-mpi

# send output to hello-mpi.out
#SBATCH --output=hello-mpi.out

# receive an email when job starts, ends, and fails
#SBATCH --mail-type=BEGIN,END,DAIL

# this job requests 32 cores. Cores can be selected from various nodes.
#SBATCH --ntasks=32

# there are a few partitions on Midway2 and it is important to specify which
# partition you want to run your job on. Not having the following line, the 
# sandby partition on Midway1 will be selected as the default partition
#SBATCH --partition=broadwl

# the --constraint=fdr or --constraint=edr options (available on Midway2 only) 
# could be given to guarantee a job will be using nodes with the FDR or EDR 
# Infiniband interconnects. Without this option, the scheduler will select 
# available nodes without considering their interconnect types. 
#SBATCH --constraint=fdr

# load the openmpi module
module load openmpi

# Run the process with mpirun. Notice -n is not required. mpirun will
# automatically figure out how many processes to run from the slurm options
