Today Bright Computing announced that the company has helped launch Denmark’s most powerful supercomputer dedicated to Life Sciences. With more than 16,000 cores, 92 TeraByte of memory, and 7.5 PetaByte of storage, the container-based supercomputer is called Computerome.

Podcast: RCE & Rex Computing Look at the Open Compute Project

RCE Podcast logo

In this RCE Podcast, Brock Palen and Jeff Squyres discuss the Open Compute Project with Thomas Sohmers from Rex Computing. “Thomas Sohmers is the founder and CEO of REX Computing. His experience includes working at the MIT Institute for Soldier Nanotechnologies for 3 years as both an end user of HPC systems, and later transitioning into designing and building them at the lab. This experience led to starting REX Computing in 2013 as a recipient of the Peter Thiel ’20 under 20′ Fellowship, where he leads the architectural design and business operations.”

Video: Nvidia’s Path to Exascale

“The end of Dennard scaling has made all computing power limited, so that performance is determined by energy efficiency. With improvements in process technology offering little increase in efficiency innovations in architecture and circuits are required to maintain the expected performance scaling. The large scale parallelism and deep storage hierarchy of future machines poses programming challenges. Future programming systems must allow the programmer to express their code in a high-level, target-independent manner and optimize the target-dependent decisions of mapping available parallelism in time and space. This talk will discuss these challenges in more detail and introduce some of the technologies being developed to address them.”

Video: APU Clusters and “Watts” Powering the Future of HPC

phil

Penguin Computing just announced the Altus Altus 2a30, a building block for the first application optimized accelerated processing unit (APU) clusters, making seamless GPU and CPU memory sharing on clusters a reality based on heterogeneous system architecture (HSA) from AMD. The shared memory capability involves very lightweight context switches to switch instantaneously between the GPU and CPU, whichever code runs best at a given moment.

Over at EE Times, Rick Merritt writes that a startup founded by two teenagers is designing a parallel processor that it hopes delivers a 10x leap in performance per watt for high-end systems.

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.”
