Not every application runs with maximum efficiency on a multiple of 32 cores. Choosing the number of cores to request, and whether or not to request whole nodes, may be a trade-off between ''running'' time (or efficient use of the computer) and ''waiting'' time (or efficient use of your time). If you want help evaluating these factors, please | Not every application runs with maximum efficiency on a multiple of 32 cores.
