Cray Shasta Software to Power Exascale Era

Today Cray a new, open and extensible software platform to address the growing need for supercomputing across government and private industries. As advanced simulation, artificial intelligence (AI) and digital transformation create new, data intensive workloads, the need for performance at scale is growing rapidly. Recognizing the challenges presented by the exascale era, Cray’s software fuses supercomputing performance and capability with the modularity, composability and ease-of-use of cloud computing.

Cray to Build El Capitan Exascale Supercomputer at LLNL

Today the Department of Energy announced that Cray will build the NNSA’s first exascale supercomputer, “El Capitan.” To be hosted at LLNL, El Capitan will have a peak performance of more than 1.5 exaflops and an anticipated delivery in late 2022. El Capitan will be DOE’s third exascale-class supercomputer, following Argonne National Laboratory’s “Aurora” and Oak Ridge National Laboratory’s “Frontier” system. All three DOE exascale supercomputers will be built by Cray utilizing their Shasta architecture, Slingshot interconnect and new software platform.

Video: HPC at CASC

CASC serves as LLNL’s window to the broader computer science, computational physics, applied mathematics, and data science research communities. In collaboration with academic, industrial, and other government laboratory partners, investigators conduct world-class scientific research and development on problems critical to national security. CASC applies the power of high-performance computing (HPC) and the efficiency of modern computational methods to the realms of stockpile stewardship, cyber and energy security, and knowledge discovery for intelligence applications.

Registration Opens for September HPC User Forum at Argonne

Registration is now open for the HPC User Forum at Argonne National Lab. “Our global steering committee representing leading HPC centers has worked with Hyperion Research to provide a powerful agenda representing key trends at the forefront of government, academic and private sector HPC use around the world. You’ll hear about recent developments in the exascale race, architectures, HPDA-AI, smart cities, cloud computing, industrial-commercial HPC and other important topics.”

Supercomputing Asteroid Impacts for Planetary Defenses

In support of NASA’s Planetary Defense Coordination Office, researchers are creating 3-D models and using one of NASA’s most powerful supercomputers to produce simulations of hypothetical asteroid impact scenarios. “Asteroid impacts are one of the only natural disasters we can actually predict and then take action to protect people,” said Michael Aftosmis, an aerospace engineer who leads the ATAP blast wave and ground damage modeling work at NAS.

AMD Powers Corona Cluster for HPC Analytics at Livermore

Lawrence Livermore National Lab has deployed a 170-node HPC cluster from Penguin Computing. Based on AMD EPYC processors and Radeon Instinct GPUs, the new Corona cluster will be used to support the NNSA Advanced Simulation and Computing (ASC) program in an unclassified site dedicated to partnerships with American industry. “Even as we do more of our computing on GPUs, many of our codes have serial aspects that need really good single core performance. That lines up well with AMD EPYC.”

DOE powers Aluminum and Steelmaking Research through HPC4Manufacturing Program

Today the HPC4Manufacturing Program announced four federal funding awards for solving key manufacturing challenges in steelmaking and aluminum production through supercomputing. “Primary metals industries are significant energy users, so opportunities to reduce energy consumption in this area is of great interest to our sponsors,” said HPC4Manufacturing Director Robin Miles of LLNL. “Additionally, this program is helping U.S. steel makers produce the higher strength steels vital to light weighting the next generation of automobiles.”

Spack – A Package Manager for HPC

Todd Gamblin from LLNL gave this talk at the Stanford HPC Conference. “Spack is a package manager for cluster users, developers and administrators. Rapidly gaining popularity in the HPC community, like other HPC package managers, Spack was designed to build packages from source. This talk will introduce some of the open infrastructure for distributing packages, challenges to providing binaries for a large package ecosystem and what we’re doing to address problems.”

Video: Sierra – Science Unleashed

Rob Neely from LLNL gave this talk at the Stanford HPC Conference. “This talk will give an overview of the Sierra supercomputer and some of the early science results it has enabled. Sierra is an IBM system harnessing the power of over 17,000 NVIDIA Volta GPUs recently deployed at Lawrence Livermore National Laboratory and is currently ranked as the #2 system on the Top500. Before being turned over for use in the classified mission, Sierra spent months in an “open science campaign” where we got an early glimpse at some of the truly game-changing science this system will unleash – selected results of which will be presented.”

Podcast Looks at Exascale Computing for Forefront Scientific Problems

In this edition of Let’s Talk Exascale, Fred Streitz of Lawrence Livermore National Laboratory describes his team’s efforts to develop supercomputer applications that address forefront scientific problems by pushing the limits of leadership-class computing. “At SC18, Fred Streitz gave a talk in the US Department of Energy booth on the topic “Machine Learning and Predictive Simulation: HPC and the US Cancer Moonshot on Sierra.” As a guest on the ECP podcast, he provides an overview and some insights from his booth talk.”
