Mail Notifications
All cluster systems permit to include a mail address into SLURM batch scripts for notification about certain job states (typically, job start and/or job end).
Please note that any mailing request is obliged to include a valid email address.
If you request an email to an invalid or non-existing email address LRZ staff will revoke your job submission rights, as a defensive measure against a denial of service attack on the LRZ mail hub.
Mail configuration in Slurm job script
Add the following lines to the Slurm header of the job script (cp. the basic job script at Running parallel jobs on the Linux-Cluster):
| #SBATCH --mail-type=end | Send an e-mail at job completion If you don't want to receive an email notification please remove this line from the job script! |
| #SBATCH --mail-user=<email_address>@<domain> | (Placeholder) e-mail address (don't forget, and please enter a valid address!) |
Please refer to https://slurm.schedmd.com/sbatch.html to learn more about mail notification.
