Hi Elisabetta. No, you normally do not need to install software on all the compute nodes separately.
It is quite common to use the 'modules' environment to manage software like this http://www.admin-magazine.com/HPC/Articles/Environment-Modules Once you have numpy installed on a shared drive on the cluster, and have a Modules file in place, your users put this at the start of their job scripts: module load numpy You might also want to look at Easybuild http://easybuild.readthedocs.io/en/latest/Introduction.html There are Easybuild 'recipes' for numpy. We use them where I work. On 17 January 2018 at 14:28, Elisabetta Falivene <e.faliv...@ilabroma.com> wrote: > Hi, > let's say I need to execute a python script with slurm.
