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 […]

DOE Resumes Webinar Series Aug. 4 on HPC Scientific Software Engineering Challenges and Best Practices

The IDEAS Productivity project, in partnership with the DOE Computing Facilities of the ALCF, OLCF, and NERSC and the DOE Exascale Computing Project (ECP) has resumed the webinar series on Best Practices for HPC Software Developers, which began in 2016. To register for the event, go here. As part of this series, one-hour webinars are offered on topics in scientific […]

Exascale Computing Project Picks Fran Hill Co-chair of Industry and Agency Council

Juny 28, 2021 — The Exascale Computing Project (ECP) has announced the selection of Dr. Frances (Fran) Hill as co-chair of the ECP Industry and Agency Council (IAC). She is chief scientist for the High Performance Computing Modernization Program (HPCMP) with the US Department of Defense (DOD) and will assume the role of ECP-IAC co-chair alongside Dave […]

Exascale Computing Project’s CEED to Hold Virtual Annual Meeting Aug. 3-4

The Exascale Computing Project‘s (ECP) Center for Efficient Exascale Discretizations (CEED) will hold a virtual annual meeting highlighting progress on high-order methods and applications on Tuesday and Wednesday, Aug. 3-4. If you plan to attend, register by Tuesday, July 27. There is no registration fee. This will be CEED’s fifth annual meeting and will use […]

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….

Let’s Talk Exascale Code Development: WDMAPP—XGC, GENE, GEM

This is episode 82 of the Let’s Talk Exascale podcast, provided by the Department of Energy’s Exascale Computing Project, exploring the expected impacts of exascale-class supercomputing. This is the third in a series on sharing best practices in preparing applications for the upcoming Aurora exascale supercomputer at the Argonne Leadership Computing Facility. The series highlights […]

Exascale Computing Project Update: Director Kothe Talks Progress, Annual Meeting Highlights

In this recent interview, the U.S. Department of Energy’s Exascale Computing Project (ECP) Director Doug Kothe provides an update on the effort to deliver a capable and sustainable exascale computing ecosystem for the nation.

ECP and ALCF to Host June 21 Twitter Chat on Extreme-scale Scientific Software Stack https://wp.me/p3RLHQ-mQa

On June 21 at 2 p.m. ET, the Exascale Computing Project (ECP) and the Argonne Leadership Computing Facility will host a chat on ECP’s Twitter account (@exascaleproject) that will address several questions concerning the Extreme-scale Scientific Software Stack (E4S) that ECP is developing for the nation’s forthcoming exascale systems. E4S will have a far-reaching impact on the […]

ECP Pushes Cross-Platform Tested Compilers for HPC and Exascale Architectures

The Exascale Computing Project (ECP) is working to combine two key technologies, LLVM and continuous integration (CI), to ensure that current and future compilers are stable and performant on high-performance computing (HPC) and exascale computer systems. The proliferation of new machine architectures has made the continuous testing and verification of software (hence the “continuous” in CI) an essential part of US Department of Energy DOE supercomputing. Valentin Clement, a software engineer at Oak Ridge National Laboratory who is part of the team working to include LLVM in the ECP CI testing and verification framework, notes, “We are working to add CI for ECP-relevant architectures. This facilitates….

Exascale Computing Project: RAJA Portability Suite Enables Performance Portable CPU and GPU HPC Codes

A growing number of HPC applications must deliver high performance on CPU and GPU hardware platforms.  One software tool available now and showing tremendous promise for the exascale era is the open-source RAJA Portability Suite. RAJA is part of the Exascale Computing Project (ECP) NNSA software portfolio and is also supported by the ECP Programming Models and Runtimes area.
