Simulating Shock Turbulence Interactions on Stampede II

In this special guest feature, Jorge Salazar from TACC writes that Researchers are using XSEDE supercomputers to better understand shock turbulence interactions. “We proposed that, instead of treating the shock as a discontinuity, one needs to account for its finite thickness as in real life which may be involved as a governing parameter in, for example, amplification factors,” Donzis said.

Supercomputing Galactic Winds with Cholla

Using the Titan supercomputer at Oak Ridge National Laboratory, a team of astrophysicists created a set of galactic wind simulations of the highest resolution ever performed. The simulations will allow researchers to gather and interpret more accurate, detailed data that elucidates how galactic winds affect the formation and evolution of galaxies.

HPC Innovation Excellence Award Showcases Physics-based Scientific Discovery

A collaboration that includes researchers from NERSC was recently honored with an HPC Innovation Excellence Award for their work on “Physics-Based Unsupervised Discovery of Coherent Structures in Spatiotemporal Systems.” The award was presented in June by Hyperion Research during the ISC19 meeting in Frankfurt, Germany.

ACM Announces Winners of 2019 ACM-IEEE CS George Michael Memorial HPC Fellowships

Today ACM announced that Milinda Shayamal Fernando of the University of Utah and Staci Smith of the University of Arizona are the recipients of the 2019 ACM-IEEE CS George Michael Memorial HPC Fellowships. “The fellowship honors exceptional PhD students throughout the world whose research focus is on high performance computing applications, networking, storage or large-scale data analytics using the most powerful computers that are currently available. The Fellowship includes a $5,000 honorarium and travel expenses to attend SC19 in Denver, where the Fellowships will be formally presented.”

Video: Big Data is Dead, Long Live Its Replacement

Tom Fisher gave this talk at the Samsung Forum. “Big Data is experiencing a second revolution. This talk will address what’s happened, how it happened and what big data is bridging too. Enterprise companies have to make business critical decisions in the coming years and the marketplace is not clear. The recent changes in the Big Data market will be reviewed as well as the effects on the related ecosystem. The goal of this presentation is to provide insights to engineers, data engineers and data scientists to better navigate a rapidly moving landscape.”

Video: Cray Steps up with 2nd Generation AMD EPYC Processors for HPC

In this video, from Forrest Norrod from AMD welcomes Peter Ungaro from Cray to discuss how 2nd Generation AMD EPYC processors with drive new levels of performance for HPC. The AMD EPYC 7002 Series Processors are the first x86 server processors featuring 7nm hybrid-multi-die design and PCIe Gen4. With up to 64 high performance cores per SOC, 2nd Gen AMD EPYC Processors deliver world-record performance on industry benchmarks. They are available in the Cray CS500 cluster and Shasta supercomputers.”

Trilce Estrada wins 2019 ACM SIGHPC Emerging Woman Leader in Technical Computing Award

Today SIGHPC announced that Trilce Estrada is the 2019 ACM SIGHPC Emerging Woman Leader in Technical Computing award winner. Dr. Estrada is an associate professor in the department of Computer Science at the University of New Mexico. She is recognized for her innovative and transformative deployment of machine learning for knowledge discovery in molecular dynamic simulations and in situ analytics. “Her contributions in computational chemistry have transformed emerging paradigms into successful platforms for scientific discovery. She is the recipient of numerous grants and awards, including an NSF CAREER Award for enabling distributed and in-situ analysis for multidimensional structured data.”

Podcast: Memory-Driven Computing

In this podcast, HPE Distinguished Technologist Kim Keeton describes the concept of Memory-Driven Computing and how it relates to traditional high performance computing. In terms of application areas, Kim also explains her perspective on blockchain and self-driving cars. “Memory-Driven Computing sets itself apart by giving every processor in a system access to a giant shared pool of memory – a sharp departure from today’s systems where relatively small amounts of memory are tethered to each processor. The resulting inefficiencies limit performance.”

Volkov and Demmel Paper on GPUs Wins SC19 Test of Time Award

Today SC19 announced the winners of the Test of Time Award. The annual award recognizes an outstanding paper that has deeply influenced the HPC discipline. We are pleased to announce the selection of the SC08 paper, “Benchmarking GPUs to Tune Dense Linear Algebra”, by Vasily Volkov (NVIDIA) and James Demmel (UC Berkeley) as the SC19 ToTA winner.

The paper was deemed deserving of the SC19 ToTA due to its first-of-its-kind vision of GPU architectures as a vector machine. By building on this vision, Volkov and Demmel defined techniques to achieve greater efficiency and performance.
