Frontier: OLCF’S Justin Whitt on Deploying the First Exascale Supercomputer

In this installment of the Let’s Talk Exascale podcast series produced by the Department of Energy’s Exascale Computing Project, Justin Whitt, program director of the Oak Ridge Leadership Computing Facility, discusses deployment of Frontier, the first U.S. exascale supercomputer. The system, built by HPE-Cray and powered by AMD microprocessors, is scheduled to be installed by […]

Exascale Hardware Evaluation: Workflow Analysis for Supercomputer Procurements

It is well known in the high-performance computing (HPC) community that many (perhaps most) HPC workloads exhibit dynamic performance envelopes that can stress the memory, compute, network, and storage capabilities of modern supercomputers. Optimizing HPC workloads to run efficiently on existing hardware systems is challenging, but attempting to quantify the performance envelopes of HPC workloads to extrapolate performance predictions for HPC workloads on new system architectures is even more challenging, albeit essential. This predictive analysis is beneficial because it helps each data center’s supercomputer procurement team extrapolate to the new machines and system architectures that will deliver the most performance for production workloads at their datacenter. However, once a supercomputer is installed, configured, made available to users, and benchmarked, it is too late to consider fundamental architectural changes.

ExaWind: How Exascale-class HPC Will Help Optimize Skyscraper-sized Wind Turbines of the Future

A wind power revolution is blowing through the U.S. electrical industry, and exascale-class supercomputing is expected to play an increasingly instrumental role in its growth. The Energy Information Administration puts wind power’s share of America’s electricity generation at 8.4 percent in 2020, up from less than 1 percent in 1990. Increasingly competitive on cost and […]

Let’s Talk Exascale: Chandrasekaran on Teaching Supercomputing and Leading ECP’s SOLLVE Project

In this episode of the Exascale Computing Project’s Let’s Talk Exascale, the ECP’s Scott Gibson interviewed Sunita Chandrasekaran, the new principal investigator of the ECP SOLLVE (Scaling OpenMP With LLVm for Exascale Performance and Portability) project. She replaces Barbara Chapman in the role, whom ECP Software Technology Director Mike Heroux said has been an invaluable […]

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 […]

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 […]
