 Another note about using Kestrel is that partial node allocations are possible, which means the full memory
 available on each node may not be assigned by default. In general, using the ``--exclusive`` flag when
 requesting nodes through the slurm scheduler, which will allocate entire nodes exlcusively for your request,
 is recommended. Otherwise, memory intensive operations such as CUDA compilation may fail. You can alternatively
