Four Challenges Facing Exascale Application Prep

Worry over readying HPC applications for exascale computing isn’t new and various efforts are underway. Whether they are sufficient is a matter of debate. A major stumbling block, of course, is no one knows precisely what exascale architecture will look like. A recent paper (June 9) on arXiv.org from IBM Research and several European academic researchers proposes an approach for tackling the problem. The paper, Challenges and Recommendations for Preparing HPC Applications for Read more…

The Necessary Marriage of Big Data with Exascale

Failure to incorporate big data computing insights into efforts to achieve exascale computing would be a critical mistake argue Daniel Reed and Jack Dongarra in their article, Exascale Computing and Big Data, published in the July issue of the Communications of the ACM journal. While scientific and big data computing have historically taken different development paths, the distinct problems they tackled are converging and lessons from both will be needed. “Just a few years ago, the very Read more…

Altair’s Bill Nitzberg Sums Up Four Decades of HPC

In a recent blog post, HPC community member and CTO of PBS Works at Altair Engineering, Inc. Dr. Bill Nitzberg, traces the recent history of computing from 1980 through the end of the present decade, to illustrate the trends that best characterize the coming exascale era. The four decades are depicted in a slide broken down by systems, data and business trajectories with circles around the areas most relevant to the needs of exaflops-class systems: Read more…

Senate and House America COMPETES Bills Face Off

Few dispute the importance of research and advanced computing technology to American competitiveness, but there is disagreement about the role of the government in funding such efforts. Currently two bills are making their way through the legislative process as potential successors to the America COMPETES Acts of 2007 and 2010 (which were passed by President George W. Bush and President Obama respectively). They are briefly summarized as follows: The House version, H.R. 1806: America Read more…
Inevitable Convergence of HPC and Big Data Satoshi Matsuoka 2015

Japan Preps for HPC-Big Data Convergence

The task of drawing discrete boundaries around the tech spheres known as HPC and big data is getting more complicated with each passing year. Many are anticipating convergence between these camps. One prominent HPCer waving the convergence flag is Satoshi Matsuoka, a professor at Tokyo Institute of Technology's Global Scientific Information and Computing Center. In his talk at the 2015 Blue Waters Symposium last month, Dr. Matsuoka made it clear that designing for data is not just a Read more…

Innovative Architecture Brings Mont-Blanc One Step Further to Exascale

BARCELONA, Spain, June 16 -- Early in February, Barcelona Supercomputing Center (BSC) successfully deployed the Mont-Blanc prototype. After three years of intensive research effort, the team installed a two-rack prototype which is now available to the Mont-Blanc consortium partners. This has been a formidable challenge as this is the first time that a large HPC system based on mobile embedded technology has

Fixating on Exascale Performance Only Is a Bad Idea

Few in the computing industry dispute that achieving ‘exascale’ performance is worthy on its own merits. But fixating only on the magic milestone (10^18 FLOPS) misses an important point – HPC as currently practiced, even at the exascale level, won’t solve the grand challenges in science and society contends Dr. Sadasivan Shankar, Harvard University visiting lecturer and long-time prominent Intel materials scientist. “I would argue that exascale is more than just exascale. It’s a new way Read more…

HP Removes Memristors from Its ‘Machine’ Roadmap Until Further Notice

One year after Hewlett-Packard launched its ambitious "this will change everything" project called "The Machine," the company is making some concessions to its initial vision, something it says is necessary in order to deliver a working prototype by next year. Announced with great fanfare at last year's HP Discovery event, the Machine was to be a reinvention of computing for the data era. It was to be special in every way -- specialized cores, a purpose-built open source operating system Read more…

Tracking the Trajectory to Exascale and Beyond

The future of high performance computing is now being defined both in how it will be achieved and in the ways in which it will impact diverse fields in science and technology, industry and commerce, and security and society. At this time there is great expectation but much uncertainty creating a climate of opportunity, challenge, and excitement. It is within this context of forging a future of computation in the crucible of innovation that we have been invited by HPCwire to host an ongoing Read more…

Early Bird Registration for ISC High Performance Conference to Close June 10

FRANKFURT, Germany, June 3 -- The early bird registration period for the 30th annual ISC High Performance conference will close next Wednesday, June 10, thus bringing the opportunity for attendees to save over 30 percent off the on-site registration rates to an end. The organizers encourage participants not to wait until the last minute to register. This year the conference will be held in a world-class Read more…
