This example is for Béluga and it assumes that full nodes are used, which gives best performance for NAMD jobs. It uses 8 processes in total on 2 nodes, each process(task) using 10 threads and 1 GPU.  This fully utilizes Béluga GPU nodes which have 40 cores and 4 GPUs per node.  Note that 1 core per task has to be reserved for a communications thread, so NAMD will report that only 72 cores are being used but this is normal.
