[slurm-users] Non-Standard Mail Notification in Job

[Daniel Miliate via slurm-users]

Newbie here, 

I'm trying to send myself an email notification with a custom body/subject for notification of important events. Is this possible? I've tried a few things in the script below.

Thanks in advance and apologies if this is not how this listing works! 

- Daniel

---- Script ---- 

....

#SBATCH --mail-user= exa...@example.example
#SBATCH --export=ALL
#SBATCH --mail-type=ALL

# Both of these work 

which mail
which mailx

EMAIL="exa...@example.example"

# Attempt 1

echo "Test email body" | mail -s "Test Subject" "$EMAIL"

# Attempt 2

mail -s "hello" "$EMAIL"   <<EOF
hello
world
EOF

# Attempt 3 

echo "Specific Information" | mail -s "SLURM Job information" $EMAIL

---- End ----

The bits you may have missed:

The emails that Slurm sends out, controlled by the SBATCH directives,
are not send from the node on which the jobs runs, but from the
controller, which will typically have been given a mail configuration
that allows it to do so.

In order to send email from a job, you would need to ensure that all
of your compute nodes can send email to the required destinations.

Onee way to test mail from your compute nodes would be to salloc an
interactive session, and see if you can run your mail/mailx commands,
from the command line, on the node you get allocated.

I used to configure Postfix on the head node.

All compute nodes are then configured to use the head node as a relay.
