Experiences with mobile processors for energy efficient HPC

Abstract

The performance of High Performance Computing (HPC) systems is already limited by their power consumption. The majority of top HPC systems today are built from commodity server components that were designed for maximizing the compute performance. The Mont-Blanc project aims at using low-power parts from the mobile domain for HPC. In this paper we present our first experiences with the use of mobile processors and accelerators for the HPC domain based on the research that was performed in the project. We show initial evaluation of NVIDIA Tegra 2 and Tegra 3 mobile SoCs and the NVIDIA Quadro 1000M GPU with a set of HPC microbenchmarks to evaluate their potential for energy-efficient HPC.
