Generalized utility metrics for supercomputers

Abstract: The problem of ranking the utility of supercomputer systems arises frequently in situations such as procurements and other types of evaluations of architectures. It is also central for any general ranking of supercomputers such as the Top500. Rankings of computer systems have traditionally solely focused on performance aspects. In recent years restrictions due to power and space requirements of large supercomputers have become very noticeable, which has increased the importance of including these factors in ge… Show more

“…This power data was also added to the TOP500 list in June 2008. The performance-power ratio is criticized, because it is an intensive metric and thus cannot be used to rank supercomputers by size; however, the ratio is useful for ranking technologies [36].…”

“…This can be seen from a figure of merit for mobile devices [19] to the SWaP metric for single servers [22] to a parameterized utility metric for supercomputers [36]. The construction principle is to multiply all desired quantities (such as performance) and divide them by undesired quantities (such as power and size).…”

“…Erich Strohmaier has pointed out that we must choose extensive metrics such as HPL that are able to rank systems in a manner that tracks growth of capability even if the metric does not reflect the rate of growth in the metics that are of most value to the user community [7]. Attempts to supplant HPL rankings have tended to fail because most common formulations of extensive metrics tend to correlate (albeit imprecisely) to the overall size of the machine.…”
