[slurm-users] slurm and singularity

[Groner, Rob]

I tried that, and it says the nodes have been allocated, but it never comes to an apptainer prompt.

I then tried doing them in separate steps.  Doing salloc works, I get a prompt on the node that was allocated.  I can then run "singularity shell <sif>" and get the apptainer prompt.  If I prefix that command with "srun", then it just hangs and I never get the prompt.  So that seems to be the sticking point.  I'll have to do some experiments running singularity with srun.

You don't often get email from frey at udel.edu. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
The remaining issue then is how to put them into an allocation that is actually running a singularity container.  I don't get how what I'm doing now is resulting in an allocation where I'm in a container on the submit node still!

Try prefixing the singularity command with "srun" e.g.


salloc <salloc-parameters> srun <srun-parameters> /usr/bin/singularity shell <path to sif>
