Exascale Grid Optimization (ExaGO), a power grid simulation and optimization platform developed by Pacific Northwest National Laboratory (PNNL), is the first of its kind to run on Oak Ridge National Laboratory’s (ORNL) Frontier, the first supercomputer in the world to reach exascale. Frontier, which was launched this spring, can calculate more than 1 quintillion operations per second and […]

ASCR: Exascale to Burst Bubbles that Block Carbon Capture
May 26, 2023 by Leave a Comment
Bubbles could block a promising technology that would separate carbon dioxide from industrial emissions, capturing the greenhouse gas before it contributes to climate change. A team of researchers with backing from the Department of Energy’s Exascale Computing Project (ECP) is out to burst the barrier, using a code that captures the floating blisters and provides insights to deter them. Chemical looping reactors (CLRs) combine fuels such as methane with oxygen from metal oxide particles before combustion. The reaction produces water vapor and carbon dioxide, which can easily be separated to create a pure CO2 stream for sequestration or industrial use. Standard post-combustion separation must pull carbon dioxide from a multigas mixture.
At ISC 2023: Hyperion Reports HPC Industry Grew 4% in 2022; AI to Drive Stronger Growth Next and Following Years
May 25, 2023 by Leave a Comment
The HPC industry managed to achieve modest overall growth in 2022, but growth of any kind was in doubt right up to the end of the year, according to HPC-AI industry analyst firm Hyperion Research, which hosted its bi-annual HPC market update at a breakfast event this week during the ISC 2023 conference in Hamburg.

@HPCpodcast: A Breakdown of the ‘Treasure Trove’ TOP500 List
May 22, 2023 by Leave a Comment
We release this special edition of the @HPCpodcast, sponsored by Lenovo, from the ISC conference in Hamburg with a detailed discussion of the new TOP500 list, issued this morning. Shahin, a list advocate, notes that it contains 30-plus years of system data showing the convolutions and evolution of the highest performing HPC architectures – “a treasure trove,” as he puts it. We offer top-line insights from the new list, not just the TOP500 but also the GREEN500, the High-Performance Conjugate Gradient (HPCG) benchmark, and the AI-inspired, mixed-precision HPL-MxP benchmark.
New TOP500 HPC List: Frontier Extends Lead with Performance Upgrade
May 22, 2023 by Leave a Comment
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 […]
‘Combustion-PELE’ on Frontier: Exascale-Class HPC for Improving Engine Efficiency
April 20, 2023 by Leave a Comment
“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.
insideHPC-Hyperion Research Interview: ITIF’s Ezell Says Global HPC-AI Leadership Is ‘Up for Grabs’
April 6, 2023 by
As we enter supercomputing’s exascale era, global HPC leadership is “up for grabs,” according to the ITIF’s Stephen Ezell, and in several ways the U.S. has relinquished leadership in the development of “feeder streams” that will supply the country’s supercomputing industry in future decades. To address this, Ezell outlines several recommended policies and initiatives the U.S. should take in the face of increasing global HPC competition.
