“Over at the Parallel for All Blog, Everett Phillips and Massimiliano Fatica write that GPUs offer good acceleration on the new HPCG benchmark that has been designed to augment Linpack as a measure of performance for the TOP500. Their GPU porting strategy focused on parallelizing the Symmetric Gauss-Seidel smoother (SYMGS), which accounts for approximately two thirds of the benchmark flops.”

University of Zurich

More robust treatments for antibiotic-resistant bacteria could result from research at the University of Zurich that simulated interactions among bacterial colonies, using an SGI supercomputer there. The research investigated the cooperation between colonies of bacteria, and could have other applications, including the treatment of Cystic Fibrosis. Dr Akos Dobay, a post-doctoral researcher for the Institute […]

In this video, Dave Hancock describes Karst, Indiana University’s newest supercomputer cluster. Housed in the IU Data Center, Karst will help researchers secure federal grants to fund discoveries, create jobs in the state, and keep sensitive data safe from cybersecurity threats.

On the Long Path to Exascale, Storage is Already Working Smarter

Infinite Memory

As the countdown to Exascale continues, Exascale-like storage problems are already showing up in today’s massively parallel, heterogeneous HPC systems. Historically, storage and I/O have kept pace with growing system demands, but, because of the limitations of spinning media and the cost of solid state storage technologies, storage performance improvements have come at a disproportionately higher cost and lower efficiency than their compute counterparts.

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.”

Webinar: Enhancing HPC Performance Through an Optimized Fabric

webinar

“Today’s High Performance Computing environments are more demanding than ever. To meet the needs of complex simulations and ever-increasing massive workloads, HPC clusters need to support faster, high core count processors, coprocessors, and higher node count clusters. Performance is key … but at what cost? In this webinar, you will learn about the factors that drive fabric performance and their impact on your investment in HPC; How the fabric is a key component of your overall HPC solution; and performance and price comparisons of some of the fabric choices available to you today.”
