Title: | Evaluating SoC power efficiency through N-body application | Authors: | Goz, David BERTOCCO, SARA CORETTI, Igor RAGAGNIN, ANTONIO TORNATORE, Luca TAFFONI, Giuliano |
Issue Date: | 2020 | Series: | INAF Technical Reports - Rapporti Tecnici INAF | Report: | 21 | Abstract: | Currently, the High Performance Computing (HPC) sector is undergoing a profound phase of innovation, in which the main stopper in order to achieve "exascale" performance is the power-consumption. The usage of "unconventional" low-cost computing systems is therefore of great interest for several scientific communities looking for a better trade-off between performance and power consumption. In this technical report, we make a performance assessment of commodity low-power System on Chip (SoC) using a direct N-body application for astrophysics. We also describe the methodology we have employed to measure the power drained by the application while running. We find that SoC technology could represent a valid alternative to traditional technology for HPC in terms of good trade-off between time-to-solution and energy-to-solution. This work arises in the framework of the ExaNeSt and EuroExa projects, which investigate the design of a SoC-based, low-power HPC architecture with a dedicated interconnection scalable to million of compute units. | URI: | http://hdl.handle.net/20.500.12386/24219 http://dx.doi.org/10.20371/INAF/TechRep/21 |
