Note: The clusters receive regular maintenance and upgrades, so at times these CPU and GPU numbers may lag behind the latest changes. To see the most up-to-date information, SSH into your cluster of interest and run the "snodes" or "shownodes" commands. To see more detailed information, connect to a compute node and run "lscpu", "lsmem", and for GPUs "nvidia-smi -a".
