Let’s Talk Exascale: How Flux Software Manages Supercomputing Workflows

This episode of the Exascale Computing Project‘s Let’s Talk Exascale podcast series delves into a software framework developed at Lawrence Livermore National Laboratory (LLNL), called Flux, which is widely used for scheduling and managing modern supercomputing and HPC workflows. Joining in the discussion are Lawrence Livermore’s Dong Ahn, Stephen Herbein, Dan Milroy and Tapasya Patki […]

Toolkit Delivers 4D Visualization, Addresses Data Volume Challenges in Exascale

The Exascale Computing Project (ECP) has announced that a team of researchers has developed the Feature Tracking Kit (FTK), which uses simplicial spacetime meshing to simplify, scale, and deliver novel feature-tracking algorithms for in situ data analysis and scientific visualization. FTK delivers feature-tracking tools, scales feature-tracking algorithms in distributed and parallel environments, and simplifies development […]

Exascale Computing Project Tabs Brookhaven’s Chandrasekaran PI of SOLLVE Project

Sept. 13, 2021 — The US Department of Energy’s (DOE’s) Exascale Computing Project (ECP) has named Sunita Chandrasekaran of Brookhaven National Laboratory (BNL) as principal investigator of the SOLLVE project. SOLLVE is advancing the OpenMP specification and its implementations to address exascale application challenges, including programmability gaps for core technologies, such as accelerator support, interoperability […]

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 […]

Argonne Picks AMD EPYC CPUs for Polaris

Santa Clara — Aug. 30, 2021 — AMD today announced that the U.S. Department of Energy’s (DOE) Argonne National Laboratory has chosen AMD EPYC processors to power the Polaris supercomputer (see earlier coverage), which will prepare researchers for the forthcoming exascale HPC system at Argonne called Aurora. Polaris will use 2nd Gen EPYC processors and then upgrade to 3rd Gen […]

NVIDIA and HPE to Deliver 2,240-GPU Polaris Supercomputer for Argonne

NVIDIA and Argonne National Laboratory this morning announced Polaris, a GPU-based supercomputer, with 2,2240 NVIDIA A100 Tensor Core GPUs delivering 1.4 exaflops of theoretical AI performance and about 44 petaflops of peak double-precision performance, up to 4X faster performance than Argonne’s current supercomputers. Argonne is calling the new system, called “Polaris,” a “testbed” supercomputer to […]

Intel Architecture Day: Details Revealed on Sapphire Rapids and ‘Powered on’ Ponte Vecchio

Harried data center and HPC server market dominator Intel today unveiled what the company said is its biggest shifts in Intel architectures in a generation. The Architecture Day event included looks at the two chips that will power the delayed Aurora exascale supercomputer, to be installed at Argonne National Laboratory; those chips are: Sapphire Rapids, […]

Add UK to Nvidia-Arm Acquisition Snags

On the heels of potential regulatory problems in China and Europe for Nvidia’s planned Arm acquisition, another press report, from Bloomberg, states that UK regulators are considering blocking the $40 billion takeover on the grounds of national security risks. It’s not known what those risks may be, but the Bloomberg story said a report by the UK government’s Competition and Markets Authority “contains worrying implications for national security, with the country now leaning towards blocking the deal,” according to an article in Data Centre Dynamics.

Let’s Talk Exascale: Optimizing the North American Power Grid for Reliability and Decarbonization

In this episode of Let’s Talk Exascale from the Department of Energy’s Exascale Computing Project (ECP) the focus is on an ECP application development project called ExaSGD, shorthand for Optimizing Stochastic Grid Dynamics at Exascale. The word “stochastic” means results are given in terms of probabilities instead of exact predictions — weather forecasting may be […]

Verifying the Universe with Exascale Supercomputers

 The ExaSky project, one of the critical Earth and Space Science applications being solved by the US Department of Energy’s (DOE’s) Exascale Computing Project (ECP), is preparing to use the nation’s forthcoming exascale supercomputers. Exascale machines will enable the ExaSky team to verify the gravitational influences, gas dynamics, and astrophysical inputs that they use to model the universe at unprecedented fidelity, as well as address forthcoming challenge problems to predict and replicate high-accuracy sky survey data.
