El Capitan Supercomputer Installation at Livermore Has Begun

With pictures to prove it, Lawrence Livermore National Laboratory announced today it has begun receiving and installing components for El Capitan, what is expected to be the third exascale-class supercomputer in the U.S. The laboratory shared photos on social media today. Projected to exceed 2 exaflops, El Capitan will likely be the most powerful supercomputer […]

EXAALT-ing Molecular Dynamics to the Power of Exascale

As part of the Exascale Computing Project (ECP), a collaborative team of scientists, software developers, and hardware integration specialists from across the Department of Energy (DOE) has developed the Exascale Atomistics for Accuracy, Length, and Time (EXAALT) application to bring molecular dynamics (MD) into the exascale era. Danny Perez, a physicist within the Theoretical Division at Los Alamos National Laboratory and the project’s principal investigator says, “We’ve implemented new scalable methods that allow us to access as much of the accuracy, length and time space as possible on exascale machines by rethinking our methods and developing algorithms that go around some of the bottlenecks that limited scaling previously.” Such a capability has potential to revolutionize MD.

GE Aerospace Runs New Engine Architecture Simulations on Frontier Exascale Supercomputer

GE Aerospace has announced that to support the development of a new open fan jet engine architecture, the organization has run simulations using Frontier, the world’s no. 1 ranked supercomputer, housed at the Department of Energy’s Oak Ridge National Laboratory. To model engine performance and noise levels, GE Aerospace created computational fluid dynamics software to run […]

New TOP500 HPC List: Frontier Extends Lead with Performance Upgrade

After a flurry of new competitors in 2022 at the top of the TOP500 list of the world’s most powerful supercomputers, the first list of 2023 – issued here in Hamburg this morning at the ISC conference – reveals the same top 10 systems in the same order. Still, the HPC community will no doubt […]

The award, sponsored by Data Center World, the global conference for data center facilities and IT professionals, recognizes […]

‘Combustion-PELE’ on Frontier: Exascale-Class HPC for Improving Engine Efficiency

“Pele” is the Exascale Computing Project’s application suite for high-fidelity detailed simulations of turbulent combustion in open and confined domains. The suite of C++-based codes comprises several repositories — PeleC (compressible solvers), PeleLM/LMeX (low-mach flow solvers), PelePhysics (thermodynamics, transport, and chemistry models), and PeleMP (multiphysics models) — that integrate block-structured adaptive mesh refinement (AMR) and cut-cell methods to simulate multifaceted combustion processes. Pele simulations provide the detailed physics and geometrical flexibility to evaluate the design and operational characteristics of clean, efficient, next-generation combustion technologies, including advanced ICEs for automotive, industrial, and aviation applications.

Orion: Frontier’s Massive File System

We’re accustomed to the massive scale of everying associated with exascale supercomputing. Now we’re getting details on the file system that will support Frontier, the world’s first exascale-certified system housed at Oak Ridge Leadership Computing Facility’s High-Performance Computing Storage and Archive Group at Oak Ridge National Laboratory. The file system, called Orion, consists of 50 cabinets […]

Dell: Threats and Opportunities for U.S. HPC Leadership

[SPONSORED GUEST ARTICLE]   Driving the development and leveraging the use of supercomputing technologies and systems is a critical strategic advantage for geopolitical players. The U.S. Council on Competitiveness, which champions entrepreneurship and commercialization of innovative ideas, coined the phrase “To Out-compute is to Out-compete” for describing the place of supercomputing as a centerpiece of competitive strategies across science, business and national defense. In fact, the U.S., having been at the forefront of supercomputing for more than 50 years, is under increasing international pressure as more countries and regions increase their investments in HPC and associated areas, including AI, applications development and optimization, and workforce development and retention.

Frontier Pushes Boundaries: 86% of Nodes Engaged on Reactor Simulation Runs

Details have trickled out of the Oak Ridge Leadership Computing Facility (OLCF) indicating progress in preparing Frontier, the exascale-class supercomputer ranked the world’s most powerful system, for full user operations. Earlier this week, the Exascale Computing Project released an article on its web site entitled “Predicting the Future of Fission Power” discussing the ExaSMR….

Quantum Computing Users Work Alongside Classical Supercomputers: An Interview with Travis Humble at Oak Ridge Lab

As the high-performance computing (HPC) community looks beyond the brink of Moore’s Law for solutions to accelerate future systems, one technology at the forefront is quantum computing, which is amassing billions of dollars of global R&D funding each year. Perhaps it’s no surprise that HPC centers — including the Oak Ridge Leadership Computing Facility (OLCF), home of the world’s first exascale supercomputer, Frontier — are finding ways to leverage
