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
