Exascale Computing Project Launches Leadership Scientific Software Portal

The Exascale Computing Project (ECP) has established the Leadership Scientific Software (LSSw) portal, where those interested can sign up for LSSw town hall (Zoom) meetings, (the first will be Thursday, Sept. 16, 3–4:30 p.m. ET) join an LSSw Slack workspace, and opt-in for a mail list that will announce LSSw events. More information can be […]

How Machine Learning Is Revolutionizing HPC Simulations

Physics-based simulations, that staple of traditional HPC, may be evolving toward an emerging, AI-based technique that could radically accelerate simulation runs while cutting costs. Called “surrogate machine learning models,” the topic was a focal point in a keynote on Tuesday at the International Conference on Parallel Processing by Argonne National Lab’s Rick Stevens. Stevens, ANL’s […]

DOE Funding $7.7M for 11 Earth & Environmental Systems Modeling Studies

Today, the U.S. Department of Energy (DOE) announced $7.7 million in funding for 11 studies to improve understanding of earth system predictability and DOE’s Energy Exascale Earth System Model (E3SM) climate model. Funding totals $7.7 million in FY2021 dollars for 11 projects lasting three years. A list of projects can be found at the BER website […]

The Whole World Is Watching: ORNL’s Bernholdt & Programming Environment Team Prepare for Frontier and Exascale

The world’s fastest supercomputer comes with some assembly required. Frontier, the nation’s first exascale computing system, won’t come together as a whole until all pieces arrive at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory to be installed—with the eyes of the world watching—on the data center floor inside the Oak Ridge Leadership Computing Facility (OLCF). Once those components operate in harmony as advertised, David Bernholdt and his team can take time for a quick bow—and then get back to work.

DOE Funds $13M for Adapting Scientific Software to Run on Exascale Supercomputers

July 21, 2021 — The U.S. Department of Energy (DOE) today announced more than $13 million for five advanced-computing projects across nine states, including $4.4 million to U.S. universities. The projects will focus on adapting scientific software to run on the coming generation of increasingly powerful supercomputers. The goal is to decrease the effort necessary […]

Spend Less on HPC/AI Storage (and more on CPU/GPU compute)

[SPONSORED POST] In this whitepaper courtesy of HPE, you’ll learn about the three approaches that can help you to feed your CPU- and GPU-accelerated compute nodes without I/O bottlenecks while creating efficiencies in Gartner’s Run category. As the market share leader in HPC servers, HPE saw the convergence of classic modeling and simulation with AI methods such as machine learning and deep learning coming and now offers you a new portfolio of parallel HPC/AI storage systems that are purpose engineered to address all of the previously mentioned challenges—in a cost-effective way.

LLVM Holds the Keys to Exascale Supercomputing

The recent proliferation of new hardware technologies has galvanized the high-performance computing (HPC) community and created the ability to deliver the nation’s forthcoming exascale-capable supercomputers and data centers. It has also made LLVM-based compiler technology the default gatekeeper to these new systems. LLVM, an open-source collection of compiler and toolchain technologies, serves as a test bed for proposed parallelization extensions (e.g., the interoperability directive in OpenMP 5.1) and as a vehicle to provide production-quality parallel compiler implementations. Johannes Doerfert, a researcher at Argonne National Laboratory, notes that “LLVM is a vehicle to provide performant implementations of OpenMP….

DOE Funding $29M to Develop Advanced Chemical Sciences Software

Today, the U.S. Department of Energy (DOE) announced $28.9 million in funding for nine research projects to advance the development of sophisticated software for the chemical sciences. Funding totals approximately $8.4 million in Fiscal Year 2021 dollars for projects of up to four years in duration, with outyear funding contingent on congressional appropriations. A list of projects can be found here. Projects funded in this announcement will develop new computational methods and open-source codes to take advantage of […]

Argonne Claims 1st Full-core Pin-resolved Nuclear Reactor Model

Understanding the physical behavior inside an operating nuclear reactor can be done only with simulations on a supercomputer due to the high-pressure, high-temperature, and radioactive environment inside a reactor core. The whirls and eddies of coolant that flow around the fuel pins play a critical role in determining the reactor thermal and hydraulics performance and […]

The US-China Supercomputing Race, Post-Exascale HPC Government Policy and the ‘Partitioning of the Internet’

All over the world, HPC has burst into geopolitics. HPC – broadly defined here as advanced supercomputing combined with big AI – is at the fault lines of national and regional rivalries, particularly between the U.S. and China, expanding in power, cost, intensity and in potential impact. Which is to say that global players put […]
