Toward a Converged Exascale-Big Data Software Stack

Within the HPC vendor and science community, the groundswell of support for HPC and big data convergence is undeniable with sentiments running the gamut from the pragmatic to the enthusiastic. For Argonne computer scientist and HPC veteran Pete Beckman, the writing is on the wall. As the leader of the Argo exascale software project and one of the principal organizers of the workshop series on Big Data and Extreme-scale Computing (Read more…

European Consortium Unveils ExaNeSt Project

Feb. 1 -- The next generation of supercomputers must be capable of a billion billion calculations per second. These are referred to as Exascale computers and with this ability to undertake such volume of calculations, they will transform our understanding of the world through advanced simulation and problem solving. It will take ten million processors working together to achieve Exascale – the equivalent of asking ten million individuals to solve, in a single second, a problem that would Read more…

Next Steps for NSCI: Seeking to Ensure a Long and Lively Lifespan

It has been six months since the White House released the executive order establishing the National Strategic Computing Initiative (NSCI), the broad interagency research effort seeking to maximize the benefits of high-performance computing (HPC) research, development and deployment across the U.S. public and private sectors. Since then, each of the participating U.S. agencies has prepared and submitted to the President's Office of Science and Technology Policy (OSTP) their specific plan for Read more…

Argonne Paves the Way for Future Systems

Last April, the third and final piece of the CORAL acquisition program clicked into place when the U.S. Department of Energy signed a $200 million supercomputing contract with Intel to supply Argonne National Laboratory with two next-generation Cray supercomputers: an 8.5-petaflop “Theta” system based on Knights Landing (KNL) and a much larger 180-petaflop “Aurora” supercomputer. The staff at the Argonne Leadership Computing Facility (ALCF), where the machines will be deployed, is Read more…

Exascale Programming: Adapting What We Have Can (and Must) Work

The demands of massive concurrency and increased resilience required for effective exascale computing have led to claims that our existing approach to application programming must be replaced. In this article I argue that disruption is inevitable but will not require new languages or programming environments. Instead disruption will be in application design, introducing new control layers that will provide the concurrency, adaptability and resilience features we need in order to achieve Read more…

SC15 Video: Mellanox’s Gilad Shainer on Co-design, Exascale, UCX, and More

Smart switches, major deployment wins, HPC Centers of Excellence, NICs with on-board FPGAs, and UCX progress were all part of Mellanox’s hectic agenda at SC15. In mid-December DoD approved Mellanox 10/40 Gigabit Ethernet switches for use in defense networks. Then last week, time ran out for acquisition target EZchip to find a higher offer seemingly clearing the way for Mellanox’s roughly $800M purchase of EZchip. These are Read more…

SC15 Video: Thomas Sterling and William Gropp Explore NSCI Opportunity

If you were hoping for a glimpse into the National Strategic Computing Initiative implementation (NSCI) plan last week while at SC15, you were out of luck. A draft, said to be quite long, has been completed but is being closely guarded at the moment. Perhaps in February, suggested William Polk of the Office of Science and Technology, closer to the final phases of federal budget preparation we’ll finally see the plan. Currently NSCI hopes are high but questions persist. Until the Read more…

Wednesday’s SC15 Twitter Roundup

The highly anticipated SC15 Twitter Roundup is finally here! In celebration of the event, we’ve decided to bring you a list of some of the top SC15 tweets that were tweeted throughout the day. For those unable to attend, we hope this gives you some insight into the happenings of SC15. Check back in tomorrow to see what’s new and perhaps you’ll even see your own tweets at some point during the Read more…

HPC ROI: Invest a Dollar to Make $500-plus Reports IDC

Perhaps the most eye-popping numbers in IDC’s HPC market report presented yesterday at its annual SC15 breakfast were ROI figures IDC has been developing as part of a DOE grant. The latest results indicated even higher ROI than shown in the pilot study. On average, according to the latest data, $514.7 in revenue are returned for every dollar of HPC invested. But first, let’s dig into the overall market numbers. After slumping in 2014, the worldwide HPC server market is poised to return Read more…

Sugon VP on Global Market Strategy, the VMware Venture and Robotic Immersive Cooling

One of the dominant themes of the latest TOP500 edition, released Monday in time for the opening of the SC15 show in Austin, was China's leap in list share by number of systems; and one of the companies that has been pivotal in this push is Sugon (formerly Dawning). Sugon (the name means Super Dragon) and its primary Chinese competitor Inspur both have a strong presence at SC this year and both also have a targeted US focused go-to-market strategy, but Sugon has a unique challenge in that Read more…
