I ended up with a more simple solution: I tweaked the program executable
(a bash script), so that it inspects which partition it is running on,
and if its the wrong one, it exits. Just added the following lines:
if [ $SLURM_JOB_PARTITION == 'big' ]; then
exit_code=126
/bin/echo "PROGRAM failed with exit code $exit_code.
PROGRAM was executed on a wrong SLURM Partition."
exit $exit_code
fi

This sounds like a solution for singularity.

You could use the Lua script to restrict what is permitted to run via
barring anything that isn't a specific singularity script. Else you
could use either prolog scripts to act as emergency fall back in case
the lua script doesn't catch it.

Juan, me kne-jerk reaction is to say 'containerisation' here.
However I guess that means that Slurm would have to be able to
inspect the contents of a container, and I do not think that is possible.
I may be very wrong here. Anyone?
However have a look at thre Xalt stuff from TACC
https://www.tacc.utexas.edu/research-development/tacc-projects/xalt
https://github.com/Fahey-McLay/xalt
Xalt is intended to instrument your cluster and collect information
on what software is being run and exactly what libraries are being used.
I do not think it has any options for "Nope! You may not run this
executable on this partition"
However it might be worth contacting the authors and discussing this.

But what if the user knows the path to such application (let's
say python command) and executes it on the partition he/she
should not be allowed to? Is it possible through lua scripts to
set constrains on software usage such as a limited shell, for
instance?
In fact, what I'd like to implement is something like a limited
shell, on a particular node for a particular partition and a
particular program.

You could do this using a job_submit.lua script that inspects
for that application and routes them properly.

Dear Community,
I have a node (20 Cores) on my HPC with two different
partitions: big (16 cores) and small (4 cores). I have
installed software X on this node, but I want only one
partition to have rights to run it.
Is it then possible to restrict the execution of an
specific application to a given partition on a given node?
Thanks
