Okay, I verified the MultipleFiles approach on a testing slurm install
with 1 control computer and two nodes and it works (with
ConstrainDevices=yes)!
Name=gpu Type=3090
MultipleFiles=/dev/nvidia0,/dev/dri/card1,/dev/dri/renderD128
Name=gpu Type=3090
MultipleFiles=/dev/nvidia1,/dev/dr
Maybe I have good news, Stephan (and others). I discovered SLURM 20.11
added a MultipleFiles option to gres.conf, which replaces File=. There
are no docs about it yet, but I found a (possibly) working snippet
making use of this option here:
https://bugs.schedmd.com/show_bug.cgi?id=11091#c13 .
emetation, which, in turn, would require changing all GPU drivers.
And it would require being able to request just chunks of GPU memory
(not sure if that's possible right now, but I think I saw some pull
request about that).
Thank you for hints!

Pinging this topic again. Nobody has an idea how to define multiple
files to be treated as a single gres?
Thank you for help,

Hello, we want to use EGL backend for accessing OpenGL without the
need for Xorg. This approach requires
that would give permissions to all three files at once.
Thank you for any tips.
