Interactive jobs on compute nodes
To work interactively on a node, e.g., to debug a running code, or test on a GPU, start an interactive session using sinteractve <compute requirements>. If no parameters were provided, the default are applied. <compute requirement> can be specified the same way as sbatch directives within an sbatch script (see Submitting jobs), as in the examples below:
$ hostname # check you are in one of the login nodes
login1.daic.tudelft.nl
$ sinteractive
16:07:20 up 12 days, 4:09, 2 users, load average: 7.06, 7.04, 7.12
$ hostname # check you are in a compute node
insy15
$ squeue -u SomeNetID # Replace SomeNetId with your NetID
JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)
2 general bash SomeNetI R 1:23 1 insy15
$ logout # exit the interactive job
To request a node with certain compute requirements:
$ sinteractive --ntasks=1 --cpus-per-task=2 --mem=4096
16:07:20 up 12 days, 4:09, 2 users, load average: 7.06, 7.04, 7.12
Warning
When you logout from an interactive session, all running processes will be terminatedNote
Requesting interactive sessions is subject to the same resource availability constraints as submitting an sbatch script. It means you may need to wait until resources are available as you would when you submit an sbatch scriptFeedback
