New HPCG Benchmark List Goes Beyond LINPACK to Compare Supercomputers


The High Performance Conjugate Gradients (HPCG) Benchmark list was announced this week at SC15. This is the fourth list produced for the emerging benchmark designed to complement the traditional High Performance LINPACK (HPL) benchmark used as the official metric for ranking the TOP500 systems. The first HPCG list was announced at ISC’14 a year and a half ago, containing only 15 entries and the SC’14 list had 25. The current list contains more than 60 entries as HPCG continues to gain traction in the HPC community.

TOP500 Shows Growing Momentum for Accelerators


Today Nvidia announced growing momentum for GPU computing as reflected in the latest TOP500 list of the world’s fastest supercomputers. “For the first time, more than 100 accelerated systems are on the list of the world’s 500 most powerful supercomputers, accounting for 143 petaflops, over one-third of the list’s total FLOPS. NVIDIA Tesla GPU-based supercomputers comprise 70 of these systems – including 23 of the 24 new systems on the list – reflecting compound annual growth of nearly 50 percent over the past five years.”

Benchmarks, Schmenchmarks: Big Iron Data and the November 2015 TOP500

Peter ffoulkes, OrionX

In this special guest feature, Peter ffoulkes from OrionX offers his insights on the latest TOP500 listing of the world’s fastest supercomputers. “Most importantly increasing the number of petascale-capable resources available to scientists, researchers, and other users up to 20% of the entire list will be a significant milestone. From a useful outcome and transformational perspective it is much more important to support advances in science, research and analysis than to ring the bell with the world’s first exascale system on the TOP500 in 2018, 2023 or 2025.”

SC15 HPC Transforms – but how, what, where, when, why and for whom?

Peter ffoulkes, OrionX

In this special guest feature from the Print’nFly Guide to SC15 in Austin, Peter ffoulkes from OrionX looks at how HPC Transforms. “If we thought the last five years were disruptive, we may not have seen anything yet, and in many ways the HPC community will continue to lead that transformation, even if it does not always receive recognition for that leadership. The general enterprise market shift towards a data-centric focus, based upon “big-data”, the impending deluge of sensor data from “The Internet of Things”, and real-time analytics using in-memory databases could be the best thing that has happened to the HPC community in decades.”

SC16 Chair Calls for HPC Organizations to Create Diversity Pages

John West, TACC

High Performance Computing has long been dominated by men, but there seems to be little hard data as to how our HPC community really looks in terms of diversity. Over at, John West calls for every HPC center, company, and research organization to create a diversity page that reflects the current state of their institution.

Czech Republic Steps Up with 2 Petaflop SGI ICE X Supercomputer


Today SGI and IT4Innovations national supercomputing center in the Czech Republic announced the deployment of the Salomon supercomputer. With a peak performance of 2 Petaflops, the Salomon supercomputer is twenty times more powerful than its predecessor and is the most powerful supercomputer in Europe running on the Xeon Phi coprocessors.

ISC 2016 Issues Call for Papers


The ISC High Performance conference has issued its Call for Papers. As Europe’s most renowned forum for high performance computing, ISC 2016 will take place June 20-22, 2016 in Frankfurt, Germany.

Maximizing Benefits of HPC with the National Strategic Computing Initiative

Jorge Titinger, SGI

“What we’re seeing in President Obama’s Executive Order is a major proof point of the importance of high-end computer technology in bolstering and redefining national competitiveness. In the past, a country’s competitiveness and global power was defined by economic growth and defense capabilities. But now we’re seeing the advent of actionable technological insight—especially derived from the power of big data—becoming a factor of a country’s power.”

Tianhe-1A Supercomputer Shuts Down After Catastrophic Blast in China

A warehouse explosion in the city of Tianjin has killed 17 people, resulting in a shutdown of the nearby Tianhe-1A supercomputer. Not to be confused with the Tianhe-2 system (currently ranked at #1), the 2.57 Petaflop Tianhe-1A system is currently #24 on the June 2015 TOP500 list.

Interview: Erich Strohmaier & Jack Dongarra on Latest TOP500


In this video from the ISC 2015 conference, Erich Strohmaier from NERSC and Jack Dongarra from University of Tennessee discuss the latest HPC trends reflected in the 45th TOP500 list. “Nine systems in the top 10 were installed in 2011 or 2012, and this low level of turnover among the top supercomputers reflects a slowing trend that began in 2008.”
