Hi, Home directory are also shared among all nodes (and head one as well). The base system (that is, local drive, including os, system files, etc) are identical and cloned based among all the hosts. If I need to install some light package (dev version of a library for example or similar) I install it over all the nodes with, for example, ansible, but this is not usual and 99% of apps, libraries or wathever, are installed on a shared location and managed with lmod.
