Argonne Claims 1st Full-core Pin-resolved Nuclear Reactor Model

Understanding the physical behavior inside an operating nuclear reactor can be done only with simulations on a supercomputer due to the high-pressure, high-temperature, and radioactive environment inside a reactor core. The whirls and eddies of coolant that flow around the fuel pins play a critical role in determining the reactor thermal and hydraulics performance and […]

The US-China Supercomputing Race, Post-Exascale HPC Government Policy and the ‘Partitioning of the Internet’

All over the world, HPC has burst into geopolitics. HPC – broadly defined here as advanced supercomputing combined with big AI – is at the fault lines of national and regional rivalries, particularly between the U.S. and China, expanding in power, cost, intensity and in potential impact. Which is to say that global players put […]

OLCF Releases Storage Specs for Frontier Exascale

A newly enhanced I/O subsystem will support the nation’s first exascale supercomputer, the HPE Cray Frontier system, and the Oak Ridge Leadership Computing Facility (OLCF). The computational might of exascale computing, expected to have top speeds of 1 quintillion — that’s 1018, or a billion billion — calculations per second, promises to enable breakthrough discoveries across the scientific spectrum when Frontier, set to power up by year’s end, opens to full user operations in 2022, from the basics of building better nuclear reactors to insights into the origins of the universe. The I/O subsystem will consist of two major components: an in-system storage layer and a center-wide file system. The center-wide file system, called Orion, will use open-source Lustre and ZFS technologies.

RPI Computer Scientist Wins NSF Award to Match Exascale Systems with Petascale Data Volumes

Rensselaer Polytechnic Institute faculty member and computer scientist George Slota has been granted a National Science Foundation Faculty Early Career Development (CAREER) award to work on the problem of enabling exascale-class system to handle gigantic, petascale-class volumes of data. “How do we best understand and get insight from this kind of data? To do that, […]

European HPC Exascale Project DEEP-EST Completed

Jülich/Munich, April 15, 2021 – The project “DEEP Extreme Scale Technologies,” funded by the European Union, has come to a successful conclusion. DEEP-EST started in 2017 to develop a modular architecture for high performance computing (HPC). Leveraging a co-design approach with real-life applications, the DEEP-EST project paved the way for future exascale systems that will […]

Univ. of Buffalo’s Paul DesJardin Elected Fellow of ASME

Paul DesJardin of the University of Buffalo has been elected fellow of the American Society of Mechanical Engineers (ASME) in recognition of his exceptional achievements and contributions to the engineering profession. ASME fellows are conferred annually and fellow is the highest grade of membership. DesJardin, professor in the Department of Mechanical and Aerospace Engineering, School […]

Porting a Particle-in-Cell Code to Exascale Architectures

By Nils Heinonen on behalf of the Argonne Leadership Computing Facility As part of a series aimed at sharing best practices in preparing applications for Aurora, we highlight researchers’ efforts to optimize codes to run efficiently on graphics processing units. Take advantage of upgrades being made to high-level, non-machine-specific libraries and programming models Developed in […]

 Preparing for Exascale: ALCF’s Aurora Early Science Program and Visualizing Cancer’s Spread

Scientists are preparing a cancer modeling study to run on Argonne’s upcoming Aurora supercomputer before it goes online in 2022. The U.S. Department of Energy’s (DOE) Argonne National Laboratory will be home to one of the nation’s first exascale supercomputers – Aurora is scheduled to arrive in 2022. To prepare codes for the architecture and scale of […]

Meet the Frontier Exascale Supercomputer: How Big Is a Quintillion?

Are all comparisons so odious, really? Some can illuminate, some can awe. HPE-Cray has put out an infographic about its Frontier exascale supercomputer, the U.S.’s first, scheduled to be shipped to Oak Ridge National Laboratory later this year. It’s got interesting comparisons that shed light on how big a quintillion is. Make that 1.5 quintillion, […]

‘Intel Is Back’: Gelsinger Delivers Upbeat Update, Expanded Manufacturing in U.S., Europe

New Intel CEO Pat Gelsinger delivered an upbeat corporate update this afternoon in the form of a webinar that emphasized Intel’s integrated device manufacturing, “IDM.2.0” strategy for manufacturing and product development that combines the company’s internal network of factories with third-party outsourced capacity and new Intel foundries in the U.S. and Europe. “As I hope […]
