Unveiling Eurora - Thermal and Power Characterization of the Most Energy-Efficient Supercomputer in the World
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. Show more
