Serial Jobs

Running a simple serial test job

This job is very simple; it just sleeps for 60 seconds.

There are sample job submission scripts available to you in the following path /opt/examples/slurm. We will copy one of these to our home directory, and submit it in this example.

$ cp /opt/examples/slurm/serial-job.sh ~/serial-job.sh

# 5min
#SBATCH --time=01:00:00

# 3GB of RAM per cpu.
