Larry Smarr Helps NCSA Celebrate 30th Anniversary

Throughout the past year, the National Center for Supercomputing Applications has been celebrating its 30th anniversary. On Friday, Larry Smarr, whose unsolicited 1983 proposal to the National Science Foundation (NSF) begat NCSA in 1985 and helped spur NSF to create not one but five national centers for supercomputing, gave a celebratory talk at NCSA.

DOE Invests $16M in Supercomputer Technology to Advance Material Sciences

The Department of Energy (DOE) plans to invest $16 million over the next four years in supercomputer technology that will accelerate the design of new materials by combining “theoretical and experimental efforts to create new validated codes.” The new program will focus on software development that eventually may run on exascale machines.

Luke Shulenburger of Sandia National Laboratories will lead a team to improve algorithms that predict and show how to modify materials properties, a key element of the DOE project. Read more…


Aquila Debuts Warm Water Cooled OCP Server

New Mexico-based technology firm Aquila is announcing the first OCP-inspired server rack to use fixed cold plate liquid cooling technology. Based on the Facebook-initiated Open Compute Project (OCP) standard, the Aquarius rack integrates patented third-generation cooling technology designed by Clustered Systems. The platform supports up to 108 Xeon servers per rack and will target high density HPC and hyperscale computing applications. Read more…

Japan’s Post-K Computer Hits 1-2 Year Speed Bump

At the HPC User Forum in Austin, Texas, Dr. Yutaka Ishikawa, project lead for RIKEN AICS, confirmed that Japan’s next-generation supercomputer, the Post-K computer, has been delayed by one-to-two years, slipping from its original 2020 target to either 2021 or 2022. The additional time is needed to ensure sufficient processor volume, sources report. With the adjusted schedule, Japan’s exascale horizon has shifted closer to the US goal to stand up a productive exascale computer by no later than 2023.

Berkeley Lab to Lead Two DOE Exascale Computing Proposals, Support Four Others

BERKELEY, Calif., Sept. 7 — Scientists at the Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) will lead or play key roles in developing 11 critical research applications for next-generation supercomputers as part of DOE’s Exascale Computing Project (ECP).

The ECP announced Sept. 7 that it has selected 15 application development proposals for full funding—of which Berkeley Lab will lead two and support four others—and seven proposals for “seed” funding, three of which will be led by Berkeley Lab, which will also support two others. Read more…

NERSC is Busily Using Dungeons to Slay Code Dragons

Work to modernize codes for use on the National Energy Research Scientific Computing Center (NERSC) Cori supercomputer and its Intel Xeon Phi Knight’s Landing manycore architecture is making steady progress, says NERSC, which has now held eight Dungeon code development sessions with Intel and Cray. The most recent was held earlier this month. These Dungeon sessions, just as the name suggests, bring NERSC researchers together with vendor experts for intense code tweaking sessions. Read more…

DOE Invests $16M in Supercomputer-based Materials Design

Materials science got a boost today when the Department of Energy announced it would invest $16 million over the next four years to accelerate the design of new materials “through use of supercomputers.” The program will focus on software development with an eye towards being able to eventually run on exascale machines.

Two four-year projects – one team led by Oak Ridge National Laboratory (ORNL), the other team led by Lawrence Berkeley National Laboratory (LBNL) – will work to develop software to design fundamentally new functional materials for applications in alternative and renewable energy, electronics, and a wide range of other fields.

Nanotech Grand Challenge & Federal Vision for Future Computing

What will computing look like in the post Moore’s Law era? There’s no shortage of ideas. A new federal white paper – A Federal Vision for Future Computing: A Nanotechnology-Inspired Grand Challenge – tackles the ‘what’s next’ question and spells out seven specific research and development priorities and identifies the federal entities responsible.

D.C. Workshop Strives to Keep NSCI Flame Burning and Growing

Last Friday, almost exactly one year after President Obama’s Executive Order establishing the National Strategic Computing Initiative (NSCI), the Office of Science and Technology Policy held a workshop in Washington D.C. ostensibly to celebrate NSCI accomplishments so far – and there are many. Just as important, the meeting sought to (re)energize NSCI’s diverse stakeholders, many of whom were early enthusiastic supporters but have become wary because of a perceived lack of action to implement NSCI.
