Eurora (EURopean many integrated cORe Architecture) is today the most energy efficient supercomputer in the world. Ranked 1st in the Green500 in July 2013, is a prototype built from Eurotech and Cineca toward next-generation Tier-0 systems in the PRACE 2IP EU project. Eurora's outstanding energy-efficiency is achieved by adopting a direct liquid cooling solution and a heterogeneous architecture with best-in-class general purpose HW components (Intel Xeon E5, Intel Xeon Phi and NVIDIA Kepler K20). In this paper we present a novel, low-overhead monitoring infrastructure capable to track in detail and in real-time the thermal and power characteristics of Eurora's components with fine-grained resolution. Our experiments give insights on Eurora's thermal/power trade-offs and highlight opportunities for run-time power/thermal management and optimization.

Abstract
Eurora (EURopean many integrated cORe Architecture) is today the most energy efficient supercomputer in the world. Ranked 1st in the Green500 in July 2013, is a prototype built from Eurotech and Cineca toward next-generation Tier-0 systems in the PRACE 2IP EU project. Eurora's outstanding energy-efficiency is achieved by adopting a direct liquid cooling solution and a heterogeneous architecture with best-in-class general purpose HW components (Intel Xeon E5, Intel Xeon Phi and NVIDIA Kepler K20). In this paper we present a novel, low-overhead monitoring infrastructure capable to track in detail and in real-time the thermal and power characteristics of Eurora's components with fine-grained resolution. Our experiments give insights on Eurora's thermal/power trade-offs and highlight opportunities for run-time power/thermal management and optimization.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
