Thank you Thomas for your suggestion. I take note of all the people’s comment and hope to come with a good solution.

I would usually suggest on a shared drive. Although it should be OK if locally installed on each compute node (probably want at same exact path and with same R packages installed). Presumably you would also want it available on the login nodes (users tend to like to see what software is installed, etc). I do not believe R is needed on the headnode (the one running the scheduler) unless that also serves as the login node. The situation for python would be the same, except that I do not recall if the slurm daemons or utilities want python (if so, you would need it on the head node, but would not need science related packages like numpy/scipy).

Execute nodes ? And is there a particular directory (path) I need to install Python and R. Background: SLURM on Ubuntu 18.04 1 headnode 4 execute nodes NFS shared drive among all nodes. Thank you all for your help. Best, Eric ._____________________________________________________________________________________________________ Eric F.
