it depends a lot on how your supercomputer is set up.
Often you can only run jobs which are "big" - either memory-wise or CPU-time wise
only as a batch job, and not interactively.
It could well be that this is exactly what causes your issue.

One way or another, typically, if you need to run a task on a remote machine
(super or not) you run it using a program called screen.

how GAP controls the amount of memory it can use, is described in the GAP
manual. Again, it is not clear how your GAP in installed, whether the amount of
RAM it can use is controlled by the supercomputer scheduler, etc...
More details would be needed - perhaps you should talk to your supercomputer
admins, too.

If you use screen, then you can have many sessions of it running, with a GAP session in each of them.

HTH,
