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.

SC16 Releases Latest Invited Talk Spotlight: Dr. Thomas Schulthess

Oct. 21 — Application performance is given much emphasis in discussions of Exascale computing. A 100-fold increase in sustained performance over today’s applications running on multi-petaflops supercomputing platforms should be the expected target for Exascale systems deployed early next decade.

In this talk we will reflect on what this means in practice and how much these Exascale systems will advance the state of the art. Read more…

NSF Awards $21.6M for Energy-Efficient Computing Projects

Developing energy efficient computing is a high priority worldwide, particularly as the race towards exascale computing heats up. As is often noted, the human brain does with 10-20 watts what supercomputers require megawatts to accomplish. This week the National Science Foundation and Semiconductor Research Corporation funded nine projects aimed at developing more energy efficient computers.

“Only disruptive breakthroughs can enable computers to perform as the human brain does, in terms of problem-solving capability and lower power, which, for the human brain, is less than a light bulb’s worth of consumption,” Read more…

Brookhaven Lab to Play Major Role in Two DOE Exascale Computing Application Projects

UPTON, N.Y., Oct. 6 — Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory will play major roles in two of the 15 fully funded application development proposals recently selected by the DOE’s Exascale Computing Project (ECP) in its first-round funding of $39.8 million. Seven other proposals received seed funding.

The ECP’s mission is to maximize the benefits of high-performance computing for U.S. Read more…

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…
