How does slurm work?

Question

linux

Hello, I was recently told about slurm, however, as usual, there was really no time to delve into the details and I had to quickly write scripts and submit them "so as not to waste time".

Well, since recently, the timeout has been constantly coming out and the scripts "do not finish" because there is simply not enough time to execute (if I understand everything correctly). In this regard, please help to understand what is happening here:

All your scripts must be signed with such a preface:

#!/bin/bash
#SBATCH --time=10:30:00
#SBATCH --account=def-myhost
#SBATCH --mem=960000M
#SBATCH [email protected]
#SBATCH --mail-type=All

I would like to know if there are time, memory and other restrictions. What other options are there? Or do they differ depending on the company that provides the service?

Thank you.

PS
I use computecanada.ca as HPC, I have a place and permission allocated there )))

There seems to be a console utility sacctmgr, which you can set and view resource limits, but I don’t know if a regular user can do it.
I would advise you to find out about the restrictions from your admins - these are always custom settings.
ps The bash tag is hardly needed here, rather Linux
