I have a code file running c2d on a state space system with an A matrix of size 62475x62475. When I ran this on a Windows 11 PC (64gb RAM), it managed to complete successfully albiet pretty slowly. However, I'm trying to run it on a cluster now with 256gb RAM on a Linux machine and it's spinning for an hour or two before force-quitting and giving me a "Killed" error. Is there any reason this might be happening? I checked ulimit -v and I'm getting the memory I expect (256gb).

Maybe there are restrictions on the allowed job size for users on the cluster ?

It's possible but my understanding was that I reserved a virtual desktop across the cluster and I have access to all the resources of the desktop (which was 256gb for me)--as opposed to submitting a job that's autoscheduled, so I'm not sure if that would be the issue(?)
