While having access to HPC, resource is not infinite, and our HPC reasonably manage job queues by how much computation you have requested recently. This provides incentive to only request enough for whatever task you work on, but for me, it hasn’t been easy: Estimating resource usage is not trivial, and trying to be as frugal as possible would sometimes result in time-consuming jobs that are terminated after several hours or days due to insufficient memory or running time requested.
