→SLURM Commands
* There are 8 nodes of that type, all currently in <code>idle</code> state
* The node names are things like <code>compute-permanent-node-68</code>
To launch a job, use [https://slurm.schedmd.com/srun.html srun] or [https://slurm.schedmd.com/sbatch.html sbatch].
* '''srun''' runs a command directly with the requested resources
* '''sbatch''' queues the job to run when resources become available
For example, suppose I have the following Shell script:
<syntaxhighlight lang="bash">
#!/bin/bash
echo "Hello, world!"
nvidia-smi
</syntaxhighlight>
I can use <code>srun</code> to run this script with the following result:
<syntaxhighlight lang="bash">
$ srun --gpus 8 ./test.sh
Hello, world!

Alternatively, I can queue the job using <code>sbatch</code>, which gives me the following result:
<syntaxhighlight lang="bash">
$ sbatch test.sh
Submitted batch job 461
</syntaxhighlight>
After launching the job, we can see it running using our original <code>squeue</code> command:
<syntaxhighlight lang="bash">
$ squeue --me
JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)
461 compute test.sh ben R 0:37 1 compute-permanent-node-285
