Job Emails

It is now possible to get emails alerts when certain event types occur using Slurms built in --mail-type SBATCH directive support.

The most commonly used valid type values are (multiple type values may be specified in a comma separated list):

• NONE (the default if you don't set --mait-type
• BEGIN
• END
• FAIL
• REQUEUE
• ALL (equivalent to BEGIN, END, FAIL, INVALID_DEPEND, REQUEUE, and STAGE_OUT)
• INVALID_DEPEND (dependency never satisfied)
• TIME_LIMIT, TIME_LIMIT_90 (reached 90 percent of time limit), TIME_LIMIT_80 (reached 80 percent of time limit), TIME_LIMIT_50 (reached 50 percent of time limit) * ARRAY_TASKS (sends emails for each array task otherwise job BEGIN, END and FAIL apply to a job array as a whole rather than generating individual email messages for each task in the job array).

The user to be notified is indicated with --mail-user, however only @hull.ac.uk email addresses are valid.

If you want to be alerted when your task completes, if it advised to use #SBATCH --mail-type=END,FAIL to catch if a job finishes cleanly or if it finishes due to an error.

Slurm Information

It is now possible to check the details of a job submission script used to submit a job. This is done using sacct -B -j <jobnumber> e.g.:

$ sacct -B -j 317
Batch Script for 317
--------------------------------------------------------------------------------
#!/bin/bash
#SBATCH -J jobsubmissionfile
#SBATCH -n 1
#SBATCH -o slurm-%j.out
#SBATCH -e slurm-%j.out
#SBATCH -p compute
#SBATCH --exclusive
#SBATCH --time=1-00:00:00
#SBATCH --mail-type=END,FAIL
#SBATCH --mail-user=<your Hull email address>

echo "This is my submission script"
sleep 10
