NSCI Discussion at HPC User Forum Shows Hunger for Details

Is the National Strategic Computing Initiative in trouble? Launched by Presidential Executive Order last July, there are still few public details of the draft implementation plan, which was delivered to the NSCI Executive Council back in October. Last week on the final day of the HPC User Forum being held in Tucson, Saul Gonzalez Martirena (OSTP, NSF) gave an NSCI update talk that contained, really, no new information from what was presented at SC15.

Compilers and More: What Makes Performance Portable?

The term performance portability has appeared many times in the past few years. What does it mean? When did we first start worrying about performance portability? Why is it more relevant now than before? Why are so many discussions about performance portability so depressing? Is there any hope? Michael Wolfe addresses these questions and more in this article.

Europe’s Fastest Supercomputer to Get Pascal GPU Upgrade

Already Europe’s fastest supercomputer at 7.8 petaflops, the Piz Daint (hybrid CPU/GPU Cray XC30) at the Swiss National Computing Center (CSCS) will double its performance with a massive upgrade that involves switching to NVIDIA’s newest Pascal GPU architecture and merging with Piz Dora (Cray XC40), a smaller CPU-based machine. The announcement was made at GTC16... Read more…

Seagate, USCAS Urge Congress to Fully Fund FY17 Supercomputing Budget

Given divided government and the election year, the U.S. FY17 budget discussions are likely to be more contentious than usual. Seagate tweeted yesterday that it and fellow industry members of the U.S. Coalition for the Advancement of Supercomputing (USCAS) had submitted a statement to Congress “advocating for full funding of the Department of Energy’s fiscal year 2017 budget request for supercomputing.”

The statement was submitted Wednesday to Chairman Mike Simpson (R-Idaho), Ranking Member Marcy Kaptur (D-Ohio), and other members of the Energy and Water Development Appropriations Subcommittee. Read more…

ANTAREX Project in HPC Wins H2020 Grant

March 18 — The ANTAREX (Autotuning and Adaptivity Approach for Energy Efficient Exascale HPC Systems) research project, coordinated by prof. Cristina Silvano from Politecnico di Milano, is a H2020 Future and Emerging Technologies (FET) programme on High Performance Computing, granted with 3 million euro, and started on Sept. 1, 2015. The project involves CINECA, the Italian Tier-0 Supercomputing Centre and IT4Innovations, the Czech Tier-1 Supercomputing Center.

Sen. Lamar Alexander: ‘Supercomputing Is One Priority We Agree On’

Increasingly, stakeholders across the public and private spheres are recognizing high-performance computing’s role as an essential competitive tool for the 21st century. The launch of the National Strategic Computing Initiative was a significant auger of HPC’s wider embrace. Together with the proliferation of HPC, the rise of China as a competitive supercomputing power could do what decades of HPC ROI reports haven’t: stir sufficient political will to unlock serious investment dollars.

NSCI Update: More Work Needed on Budgetary Details and Industry Outreach

Although initial FY17 budget proposal numbers for the first full year of the NSCI are available, they do not paint a complete picture of where the program currently stands, and based on the broad range of technical – and non-technical – challenges outlined in the original plan, there may be additional groundwork needed to ensure this program has the best chance of reaching its full potential.

NSF Seeks ‘Breakthroughs’ for Energy-Efficient Computing

Breakthroughs, by their nature, are rarely generated on demand. That said, the energy problem in computing today is so acute that the National Science Foundation and Semiconductor Research Corporation are joining forces to stimulate research into developing ‘breakthroughs’ in energy-efficient computing. The new NSF-NRC grants program, Energy-Efficient Computing: from Devices to Architectures (E2CDA), has a budget of up to $4 million per year and is currently seeking proposals due in late March.
