	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]].		Not every application runs with maximum efficiency on a multiple of 32 (or 40, or 48) cores.
