National Strategic Computing Initiative (NSCI)

Podcast: Industry Leaders on the Promise & Peril of NSCI

Five senior executives from Cray, HP, IBM, Intel and SGI weigh in on the new National Strategic Computing Initiative’s (NSCI) prospects in this exclusive HPCwire podcast. Discussion ranged widely from the need for long-term funding for leading edge technology, to the software industry’s past slowness to get involved with advancing hardware technology development, to fostering new HPC talent – even on whether the creation of a U.S. Department of IT makes sense. These are still early Read more…

IBM and GENCI Team to Drive Supercomputing Closer to Exascale

PARIS, France, Aug. 28 -- IBM and GENCI, the high performance computing agency in France, today announced a collaboration aimed at speeding up the path to exascale computing – the ability of a computing system to perform at least one exaflop, or a billion billion calculations, in one second. Currently the fastest systems in the world perform between ten and 33 petaflops, or ten to 33 million billion calculations per second – roughly one to three percent the speed of exascale.  Put into Read more…

HPC User Forum Panel will Dig into NSCI’s Promise and Peril

What’s next for the National Strategic Computing Initiative? The HPC User Forum will start the process of answering that question by presenting the first public panel of speakers from NSCI lead agencies at its September meeting in Denver. Budgets, technology goals, industry collaboration, governance are all likely to be fair game at this meeting of heavy hitters from the HPC community drawn from academia, industry and government. “We are getting a lot of interest from industry as they Read more…

Reading List: Fault Tolerance Techniques for HPC

Among the chief challenges of deploying useful exascale machines, resilience looms large. Today's error rates combined with tomorrow's node counts cannot sustain a productive workflow without intervention. The significance of this issue has not gone unnoticed. A comprehensive collection of fault tolerance techniques are presented in one volume, called "Fault Tolerance Techniques for High-Performance Computing," by editors Thomas Herault and Yves Robert -- Read more…

New National HPC Strategy Is Bold, Important and More Daunting than US Moonshot

“In order to maximize the benefits of HPC for economic competitiveness and scientific discovery, the United States Government must create a coordinated Federal strategy in HPC research, development, and deployment.” With these words, the President of the United States established the National Strategic Computing Initiative (NSCI) through Executive Order to implement this Read more…

Japan Takes Top Three Spots on Green500 List

Japan, the island nation renowned for its energy and space-saving design prowess, just nabbed the top three spots on the latest Green500 list and claimed eight of the 20 top spots. The Shoubu supercomputer from RIKEN took top honors on the 17th edition of the twice-yearly listing, becoming the first TOP500-level supercomputer to surpass the seven gigaflops-per-watt milestone. Green500 list founder Wu-chun Feng, who goes by "Wu," notes that being a small nation from a population Read more…

White House Launches National HPC Strategy

Yesterday’s executive order by President Barack Obama creating a National Strategic Computing Initiative (NSCI) is not only powerful acknowledgment of the vital role HPC plays in modern society but is also indicative of government’s mounting worry that failure to coordinate and nourish HPC development on a broader scale would put the nation at risk. Not surprisingly, early reaction from the HPC community has been largely positive. “My first reaction is that this is a long needed Read more…

AMD’s Exascale Strategy Hinges on Heterogeneity

In a recent IEEE Micro article, a team of engineers and computers scientists from chipmaker Advanced Micro Devices (AMD) detail AMD’s vision for exascale computing, which in its most essential form combines CPU-GPU integration with hardware and software support to facilitate the running of scientific workloads on exascale-class systems.

DOE Exascale Plan Gets Support with Caveats

The DOE and the National Nuclear Security Administration (NNSA) plan to develop and deploy exascale technology by 2023 received strong backing yesterday from an Advanced Scientific Computing Advisory Committee (ASCAC) sub-committee but with caveats in the form of seven recommendations for strengthening management of the Exascale Computing Initiative (ECI). Subcommittee chair, Dan Reed, vice president for research and economic Read more…

Tackling Power and Resilience at Exascale

Although the utility of FLOPS-driven benchmarks can make for interesting debate, the fact remains that major supercomputing milestones, like 1,000X performance advances, are integral to scientific discovery and also serve to drive interest and investment in the HPC ecosystem at large. The boon of accelerators helped propel HPC past the petascale marker in 2008, but fielding an exaflops-class machine has been a little trickier. While a diminished Moore's law is partly to blame, the role Read more…

China Scores Fifth TOP500 Win with Tianhe-2

When China grabbed the TOP500 crown for its Tianhe-2 supercomputer in June 2013 with double the peak FLOPS of the next fastest machine (Titan at Oak Ridge National Laboratory), could anyone have foreseen that the machine would still hold on to the top spot a full two years later? As we can see from the 45th edition of the twice-yearly TOP500 list, which was published Monday in tandem with the 2015 International Read more…
