In the late 1990s, powerful economic forces led to the adoption of commodity desktop processors in high-performance computing. This transformation has been so effective that the June 2013 TOP500 list is still dominated by x86. In 2013, the largest commodity market in computing is not PCs or servers, but mobile computing, comprising smart-phones and(More)
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(More)
Energy efficiency is a first-order concern when deploying any computer system. From battery-operated mobile devices, to data centers and supercomputers, energy consumption limits the performance that can be offered. We are exploring an alternative to current supercomputers that builds on the small energy-efficient mobile processors. We present results from(More)
Power consumption and energy efficiency are becoming critical aspects in the design and operation of large scale HPC facilities, and it is unanimously recognised that future exascale supercomputers will be strongly constrained by their power requirements. At current electricity costs, operating an HPC system over its lifetime can already be on par with the(More)
