Hey Shehab, I've been working with gem5 on my group's research cluster for a while now. 1) Gem5 isn't very memory hungry in my experience, sometimes long simulations (I'm talking 3 weeks+) will start bloating to GB of RAM but its usually not paging so it doesn't slow things down (depends on the program you are running) I exclusively use Syscall Emulation mode, so that may not apply in Full System.
*It is however single-threaded. So if your entire group is running many experiments at the same time make sure you have a ton of cores.* 2) As for job management, I created my own system for configuring/running/parsing etc.that I've built with python. gem5 as of recently has been shipped with dockerfiles. I use the gcn3 dockerfile for instance. I'd recommend using them. Again I use a custom solution here, but I'm pretty sure container job management is a solved problem. I think one of them is "kubernets" (see https://kubernetes.io/) I don't have experience with anything like that, but I'm sure that would be useful. Also, if you plan on editing gem5 and your sourcecode is going to be located on the cluster, I'd recommend using code-server ( https://github.com/cdr/code-server) It broadcasts an instance of vscode to a web page that you can access from anywhere. I used to use gvim and bash scripts and it was hell. Code server was a life-saver. If you (or anyone else) already have a solution for editing code on the cluster I would be interested in what it is. Good luck!
