High Performance Computing on Low Power Devices

Popis výsledku v původním jazyce

Nowadays, the power efficiency of modern processors is becoming more and more important next to the overall performance itself. Many programming tasks and problems do not scale very well with higher number of cores due to being memory or communication bound, therefore it is often not beneficial to use faster chips to achieve better runtimes. In this case, employing slower low power processors or accelerators may be much more efficient, mainly because it is possible to get the same results using much less energy and possibly after the same amount of time, given the algorithm can scale to higher number of cores after apply-ing some adjustments fitting the low power architecture. This paper describes the benefits of using low power chips for building an HPC cluster, the group of algorithms where this approach can be useful, results achieved so far and future plans.
