A Leap Forward in Efficiency with Real-Time PUE

Over at Datacenter Knowledge, Patrick Flynn from IOhttp://www.io.com/ writes one-time PUE measurements are not an effective measure of energy efficiency and that real-time PUE is the wave of the future. With a data center industry mandate for greater energy efficiency, we need to evolve to newer, enhanced measurement models. Though a retroactive, building-averaged PUE may serve to confirm overall progress, it falls short of helping to pinpoint opportunities for improvement.

Software Development Standards for Next-gen HPC Systems

John Barr asks what standard approach can the industry agree on to make next-generation HPC systems easier to program? When the architecture of high-performance computing (HPC) systems changes, the tools and programming paradigms used to develop applications may also have to change. We have seen several such evolutions in recent decades, including the introduction of multiprocessors, the use of heterogeneous processors to accelerate applications, vector processors, and cluster computing. .

Interview: The Software Imperative for Supercomputing

In a newly posted interview, Cray’s Jay Gould describes how the supercomputing world has changed and why the company has nearly a 5:1 ratio of software engineers to hardware engineers. You can’t just clock processors faster or add more cores and expect a supercomputer to go faster. What if the code is...

ARM for HPC Will be Build-what-you-want Style

Over at the ARM Blog, Andrew Sloss writes that the ARM approach to Big Data and HPC sets out to maximize efficiency by not over-designing any particular component. The next era of systems will follow a-build-what-you-want style. By allowing the targeting of a SoC (System-on-Chip) to solve specific problems –...
