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
“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.

insideHPC-Hyperion Research Interview: Argonne’s Rick Stevens on the Future of Everything – U.S. Post-Exascale Strategy, AI for Science, HPC in 2040 and an Aurora Install Update
March 24, 2023 by
In this interview conducted on behalf of HPC analyst firm Hyperion Research, we spoke with Argonne National Laboratory’s Rick Stevens about the present and future of HPC. The starting point for this conversation is a presentation Stevens gave at a Hyperion event in Washington related to implementation of the CHIPS and Science Act and includes his insights on the post-exascale build-out of an integrated network of U.S. supercomputing capacity (the Integrated Research Infrastructure, or IRI). We then look at AI for science and the use of data-driven modeling and simulation, which shows the potential to deliver major performance gains for researchers….
Intel Alters HPC-AI Roadmap: ‘Rialto Bridge’ GPU Discontinued
March 6, 2023 by
After business hours on Friday, Intel released information on a “streamlined and simplified” data center GPU roadmap with direct impact on HPC and AI. The new plan calls for the discontinuation of the “Rialto Bridge” GPU, which was to have succeeded the Ponte Vecchio chip that itself was delayed several years before shipments began last […]
