SLURM-Interactive Jobs

From ALICE Documentation

Interactive jobs

Interactive jobs use the command salloc to allocate resources and put you in an interactive shell on compute node(s). Review the Determining What Resources to Request section above to determine which resources you may need to include as options for these commands.

Interactive jobs can be a helpful debugging tool for creating job scripts for batch job submission, described in the next section. This allows you to experiment on compute nodes with command options, and environmental variables, providing immediate feedback, which can help determine your workflow.

salloc [options]

Recommendation: use of the option --ntasks enables Slurm to be efficient when allocating resources.

For testing, we recommend the following script as a starting point:

salloc --ntasks=8 --time=1:00:00 --mem-per-cpu=2GB
