I know this might sounds as a very basic question: where in the cluster should I install Python and R?<br>
Headnode?<br>
Execute nodes ?<br>
<br>
And is there a particular directory (path) I need to install Python and R.<br>
<br>
Background:<br>
SLURM on Ubuntu 18.04<br>
1 headnode<br>
4 execute nodes<br>
NFS shared drive among all nodes.<br>
<br>
Thank you all for your help.<br>

(N)Either - install them in directories on the NFS shared drive so that all nodes have access to them. You'll then need to either manually set PATH and other environment variables or use module files to manage these.<br>
<br>
Presumably all nodes, head and execute, are running the same version of the same OS otherwise that could cause a problem with libraries, etc.<br>
