Script that runs a serial command "hostname" on the
specified number of nodes and with the specified number of
instances.  The output will go into the slurm default output
file slurm-xxxxxx.out where xxxxxx is the job id.

Here we ask for 2 nodes and 4 tasks per node.  Specifying
ntasks=8 is redundant but if you specify all three parameters
they must be consistent.

Usage:
sbatch –A=myaccount --partition=debug  hostname.sh

# Go to the directoy from which our job was launched
cd $SLURM_SUBMIT_DIR

#run an application
srun hostname
date

Example Output:

cat slurm-5357831.out
