Large parallel job, not a multiple of whole nodes
Not every application runs with maximum efficiency on a multiple of 32 (or 40, or 48) 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 contact Technical support.
