Slidecast: Energy-efficient Computation

mark

“A crazy idea was born at ISC14 while answering questions about the new energy metrics in Allinea Performance Reports and Allinea MAP – could the information in these reports show us an easy way to increase energy efficiency without having to change the program? The idea was to use CPU frequency scaling to run memory-bound jobs at a lower clock frequency. In Lazy Energy Efficiency Challenge One, I found that on a synthetic benchmark I could increase the iterations per watt by 19% on a memory-bound code.”

“NREL’s HPC center is home to the largest HPC system in the world dedicated to advancing renewable energy and energy efficiency technologies. In addition, the HPC data center is one of the most energy efficient data centers in the world, featuring warm-water liquid cooling, and waste heat capture and re-use to reduce energy use and lower costs.”

Open Compute Project Spurs HPC Innovation for Large and Small Organizations

Phil Pokorny

In this special guest feature, Penguin Computing Chief Technology Officer Phil Pokorny writes that Open Compute Project has great potential to spark HPC innovation. In just three and a half years since Facebook announced the Open Compute Project (OCP), the cooperative industry effort is showing exceptional progress toward delivering significantly more efficient hardware into the […]

Radio Free HPC Looks at How Paypal is Using DSPs for Systems Intelligence

“PayPal’s novel approach is to convert events represented in a plain text format into a numeric format which can be analyzed in real-time using mathematical techniques with hardware specifically designed to operate on such numeric data. The first instantiation of this approach uses ProLiant m800 cartridges powered by TI’s 66AK2Hx DSP processor.”

Interview: Behind the Scenes at the DEEP Project

Estela Suarez, Project Manager of DEEP & DEEP-ER at Jülich

“In terms of the hardware, one of the biggest successes surely was to make the Intel Xeon Phi boot via the Extoll network. This might not sound so special, but for the DEEP project it is – because this basically is the essential milestone for proving our architectural concept: The Cluster-Booster approach. In traditional heterogeneous architectures the accelerators cannot boot without a host CPU. Our aim was to develop a cluster – made up of usual CPUs – and a booster – made up of accelerators – that can both act autonomously while being interconnected via two networks.”
