The recent proliferation of new hardware technologies has galvanized the high-performance computing (HPC) community and created the ability to deliver the nation’s forthcoming exascale-capable supercomputers and data centers. It has also made LLVM-based compiler technology the default gatekeeper to these new systems. LLVM, an open-source collection of compiler and toolchain technologies, serves as a test bed for proposed parallelization extensions (e.g., the interoperability directive in OpenMP 5.1) and as a vehicle to provide production-quality parallel compiler implementations. Johannes Doerfert, a researcher at Argonne National Laboratory, notes that “LLVM is a vehicle to provide performant implementations of OpenMP….
DOE Funding $29M to Develop Advanced Chemical Sciences Software
June 22, 2021 by
Today, the U.S. Department of Energy (DOE) announced $28.9 million in funding for nine research projects to advance the development of sophisticated software for the chemical sciences. Funding totals approximately $8.4 million in Fiscal Year 2021 dollars for projects of up to four years in duration, with outyear funding contingent on congressional appropriations. A list of projects can be found here. Projects funded in this announcement will develop new computational methods and open-source codes to take advantage of […]
Argonne Claims 1st Full-core Pin-resolved Nuclear Reactor Model
June 10, 2021 by
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’
May 28, 2021 by
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
May 21, 2021 by
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
May 4, 2021 by
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
April 15, 2021 by
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 […]

Porting a Particle-in-Cell Code to Exascale Architectures
April 2, 2021 by
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
March 26, 2021 by
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 […]
