Sandia to receive Fujitsu supercomputer processor

This spring, CCR researchers anticipate Sandia becoming one of the first DOE laboratories to receive the newest A64FX Fujitsu processor, a Japanese Arm-based processor optimized for high-performance computing.The 48-core A64FX processor was designed for Japan’s soon-to-be-deployed Fugaku supercomputer, which incorporates high-bandwidth memory. It also is the first to fully utilize wide vector lanes that were designed around Arm’s Scalable Vector Extensions. These wide vector lanes make possible a type of data-level parallelism where a single instruction operates on multiple data elements arranged in parallel. Penguin Computer Inc. will deliver the new system — the first Fujitsu PRIMEHPC FX700 with A64FX processors. Sandia will evaluate Fujitsu’s new processor and compiler using DOE mini- and proxy-applications and will share the results with Fujitsu and Penguin. More details are available here.

Sandia-led Supercontainers Project Featured in ECP Podcast

As the US Department of Energy’s (DOE) Exascale Computing Project (ECP) has evolved since its inception in 2016, what’s known as containers technology and how it fits into the wider scheme of exascale computing and high-performance computing (HPC) has been an area of ongoing interest in its own right within the HPC community.

Container technology has revolutionized software development and deployment for many industries and enterprises because it provides greater software flexibility, reliability, ease of deployment, and portability for users. But several challenges must be addressed to get containers ready for exascale computing.

The Supercontainers project, one of ECP’s newest efforts, aims to deliver containers and virtualization technologies for productivity, portability, and performance on the first exascale computing machines, which are planned for 2021.

ECP’s Let’s Talk Exascale podcast features as a guest Supercontainers project team member Andrew Younge of Sandia National Laboratories. The interview was recorded this past November in Denver at SC19: The International Conference for High Performance Computing, Networking, Storage, and Analysis.

Steve Plimpton Awarded the 2020 SIAM Activity Group on Supercomputing Career Prize

Steve Plimpton has been awarded the 2020 Society for Industrial and Applied Mathematics (SIAM) 2020 Activity Group on Supercomputing Career Prize.  This prestigious award is given every two years to an outstanding researcher who has made broad and distinguished contributions to the field of algorithm development for parallel scientific computing.  According to SIAM, the Career Prize recognizes Steve’s “seminal algorithmic and software contributions to parallel molecular dynamics, to parallel crash and impact simulations, and for leadership in modular open-source parallel software.”

Steve is the originator of several successful software projects, most notably the open-source LAMMPS code for molecular dynamics.  Since its release in 2004, LAMMPS has been downloaded hundreds of thousands of times and has grown to become a leading particle-based materials modeling code worldwide.  Steve’s leadership in parallel scientific computing has led to many opportunities for the Center for Computing Research to collaborate on high-performance computing projects both within and outside Sandia National Laboratories.
