Le supercalculateur « Fugaku », qui s'est classé numéro un dans plusieurs listes de supercalculateurs, y compris le Top500 en juin 2020, possède diverses fonctionnalités de contrôle de puissance, telles que (1) un mode éco qui n'utilise qu'un des deux pipelines à virgule flottante tout en diminuant la puissance. alimentation de la puce ; (2) un mode boost qui augmente la fréquence d’horloge ; et (3) une fonction de rétention des cœurs qui transforme les cœurs inutilisés en état de faible consommation. En orchestrant ces fonctionnalités de performance énergétique tout en tenant compte des caractéristiques des applications en cours d’exécution, nous pouvons potentiellement obtenir une efficacité énergétique encore meilleure au niveau du système. Dans cet article, nous rendons compte des performances et de la consommation d'énergie de Fugaku à l'aide des benchmarks SPEC HPC. Par conséquent, nous avons confirmé qu'il est possible de réduire l'énergie d'environ 17 % tout en améliorant les performances d'environ 2 % par rapport au mode normal en combinant le mode boost et le mode éco.

Abstract: The supercomputer, “Fugaku”, which ranked number one in multiple supercomputing lists, including the Top500 in June 2020, has various power control features, such as (1) an eco mode that utilizes only one of two floating-point pipelines while decreasing the power supply to the chip; (2) a boost mode that increases clock frequency; and (3) a core retention feature that turns unused cores to the low-power state. By orchestrating these power-performance features while considering the characteristics of running applications, we can potentially gain even better system-level energy efficiency. In this paper, we report on the performance and power consumption of Fugaku using SPEC HPC benchmarks. Consequently, we confirmed that it is possible to reduce the energy by about 17% while improving the performance by about 2% from the normal mode by combining boost mode and eco mode.
