Let’s Talk Exascale: Container Technologies for Exascale Computing

In this episode of the Exascale Computing Project’s (ECP) Let’s Talk Exascale podcast series, Andrew Younge of Sandia National Laboratories discusses container technology and how it fits into the wider scheme of exascale and high-performance computing (HPC). Container technology has revolutionized software development by providing greater software flexibility, reliability, ease of deployment and portability. But […]

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 […]

A Look Inside the US’s 1st Exascale Supercomputer Facility

Preparing for the nation’s first exascale system, the upcoming HPE Cray EX Frontier “Frontier” system at the US Department of Energy’s (DOE’s) Oak Ridge National Laboratory (ORNL), has been a colossal undertaking. Since the spring of 2020, ORNL staff members have made numerous modifications to the building and room that will house Frontier, a system that will […]

Ruby Leung, Chief Scientist for Energy Exascale Earth System Model Project, Named a DOE Distinguished Scientist Fellow.

Ruby Leung likes to ask questions. That started at her high school in Hong Kong, where she also became interested in science. “I was one of those kids in science who always was curious. And then you can find the answers,” said Leung, an atmospheric scientist at Pacific Northwest National Laboratory (PNNL) in Richland, Washington. “Of course, after you […]

Preparing for Exascale: Aurora to Drive Brain Map Construction

The U.S. Department of Energy’s Argonne National Laboratory will be home to one of the nation’s first exascale supercomputers when Aurora arrives in 2022. To prepare codes for the architecture and scale of the system, 15 research teams are taking part in the Aurora Early Science Program through the Argonne Leadership Computing Facility (ALCF), a […]

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 […]

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 […]

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.
