ECP and ALCF to Host June 21 Twitter Chat on Extreme-scale Scientific Software Stack https://wp.me/p3RLHQ-mQa

On June 21 at 2 p.m. ET, the Exascale Computing Project (ECP) and the Argonne Leadership Computing Facility will host a chat on ECP’s Twitter account (@exascaleproject) that will address several questions concerning the Extreme-scale Scientific Software Stack (E4S) that ECP is developing for the nation’s forthcoming exascale systems. E4S will have a far-reaching impact on the […]

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 […]

Exascale Computing Project: RAJA Portability Suite Enables Performance Portable CPU and GPU HPC Codes

A growing number of HPC applications must deliver high performance on CPU and GPU hardware platforms.  One software tool available now and showing tremendous promise for the exascale era is the open-source RAJA Portability Suite. RAJA is part of the Exascale Computing Project (ECP) NNSA software portfolio and is also supported by the ECP Programming Models and Runtimes area.

6,000 GPUs: Perlmutter to Deliver 4 Exaflops, Top Spot in AI Supercomputing

The U.S. National Energy Research Scientific Computing Center today unveiled the Perlmutter HPC system, a beast of a machine powered by 6,159 Nvidia A100 GPUs and delivering 4 exaflops of mixed precision performance. Perlmutter is based on the HPE Cray Shasta platform, including Slingshot interconnect, a heterogeneous system with both GPU-accelerated and CPU-only nodes. The system […]

A New Approach to Storage and Data Management

In this sponsored post, Olivier Multon, Storage & Data Management Product Manager, Atos, BDS – Big Data & Security, believes that
with the expansion of data-intensive applications, storage has been highlighted as a critical factor in HPC. Data Management is key to optimize your entire system’s speed and performance. High-performance storage enables organizations to take full advantage of highly parallel applications and thus harness the power of supercomputing.

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, […]

New Hypre Library Approach Brings GPU-Based Algebraic Multigrid to Exascale and HPC Community

First developed in 1998, the hypre team has adapted their cross-platform high performance library to support a variety of machine architectures over the years. Hypre supports scalable solvers and preconditioners that can be applied to large sparse linear systems on parallel computers.[i] Their latest work now gives scientists the ability to efficiently utilize modern GPU-based extreme scale parallel supercomputers to address many scientific problems.

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 […]
