I have installed Einstein Toolkit on my laptop and run a low-resolution simulation of a TOV star.<br>
Everything worked fine, no problems encountered.<br>
<br>
However, as probably most users interested in using ET, I would like to install it on a cluster to study something more computationally demanding.<br>
<br>
The CactusTutorial jupyter notebook for new users does not tackle this scenario in detail.<br>
Understandably, it would be unrealistic to provide generic instructions that cover all cluster configurations.<br>
How about guidelines that cover some common scenarios though? (e.g. a cluster that organizes libraries and packages as modules and also uses the Spack manager)<br>

Is there some documentation that gives basic guidelines as to how setup ET on a cluster aimed at a user profile that has (obviously) no previous experience with ET, simfactory etc and (quite possibly) also limited experience on how HPC clusters are setup, how
packages are installed etc?</div>

This request stems from the fact that I have been discovering little-by-little and through trial-and-error that e.g. running `./simfactory/bin/sim setup-silent` as outlined in the CactusTutorial, makes no sense for the case of a cluster.<br>
In my opinion, and if I may offer a suggestion, it would be a good idea to underline this distinction in a future revision of the tutorial.<br>
<br>
Furthermore, another crucial step to setup ET on a cluster seems to be that the user must create "manually" their respective "<my_cluster>.cfg" and "<my_cluster>.ini" files and possibly the corresponding run and submit scripts.<br>
Could you confirm that this is indeed the case?<br>
What is the recommended course of action to do this?<br>
Maybe one should start by copying a sample ".cfg" file and amend it with information found from their cluster's technical documentation?<br>
<br>
I can follow up with more specific questions about problems I encountered during my so far unsuccessful attempts to install ET on a cluster, but to avoid people having to repeat explanations already given in the past, I would like first to make sure that I
am not missing some source of information/documentation already available.<br>
<br>
Also, in the long shot that someone has already installed ET on one of the CINECA clusters in Italy (I am trying to install ET on the Leonardo cluster), I would be grateful if you could share your insights!<br>
