DDN: Enabling Scientific Discovery and Exascale Initiatives

Alex Bouzari gave this talk at the DDN User Group. “The goal of the event is to gather the community during ISC to discover how HPC organizations are assessing and leveraging technology to raise the bar on HPC innovations and best practices. From exciting user presentations to engaging roundtable conversations and groundbreaking technology updates, this can’t-miss event delivers the ideas and inspiration to help your cutting-edge HPC initiatives transform the world.”

Video: Computational Discovery in the 21st Century

Nicola Marzari from EPFL gave this public lecture at PASC17. “The talk offers a perspective on the current state-of-the-art in the field, its power and limitations, and on the role and opportunities for novel models of doing computational science – leveraging big data or artificial intelligence – to conclude with some examples on how quantum simulations are accelerating our quest for novel materials and functionalities.”

Video: Flash Poster Session at PASC17

In this video from PASC17, Maria Grazia Giuffreda (ETH Zurich / CSCS, Switzerland) moderates a Flash Poster Session. “The aim of this session is to allow poster presenters to introduce the topic of their poster and motivate the audience to visit them at the evening poster session. Authors will be strictly limited to 40 seconds each – after this time the presentation will be stopped automatically.”

Univa Powers Formula One and More at ISC 2017

In this video from ISC 2017, Gaétan Didier Head of CFD, Sahara Force India Formula One Racing Team describes how he uses Univa software to manage CFD workloads that simply cannot be done in a wind tunnel. After that, Bill Bryce from Univa describes how the company’s software powers simulation for everything from Formula 1 racing to manufacturing and life sciences.

Video: OpenACC Update from ISC 2017

In this video from ISC 2017, Sunita Chandrasekaran and Michael Wolfe present an overview of OpenACC and a preview of upcoming GPU Hackathon events. “OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers interested in porting their codes to a wide-variety of heterogeneous HPC hardware platforms and architectures with significantly less programming effort than required with a low-level model.”

Video: Unlocking the Mysteries of the Universe with Supercomputers

Katrin Heitmann from the University of Chicago presented this talk at PASC17. “In this talk I will introduce HACC, the Hardware/Hybrid Accelerated Cosmology Code, which is being developed to combat the tremendous computational challenge to simulate our Universe.” After the talk, she discusses Dark Matter with Rich Brueckner from insideHPC.

Deep Learning Comes to the Student Cluster Competition

“We decided to use a slightly more interesting use case of solving for Captcha because it not only highlights the power of deep learning to be a useful tool create models to recognize and classify unwieldy data, such as distorted characters, grainy images and overlapping characters, but it also demonstrates that it is possible for this powerful technology to be used in less positive ways, such as solving for security or privacy. Realizing that everyone has access to the tools we use to move society forward, we need to be aware of the possible mis-use, especially as it becomes more pervasive across industry, healthcare, financial services, and the like.”

Video: Increasing Efficiency of Sparse Matrix-Matrix Multiplication

“Given the importance of the precise sparsity pattern, and even the actual matrix data, which decides the effective fill-in upon multiplication, the tests are performed within the CP2K package with application benchmarks. Results show a substantial boost in performance for the RMA based 2.5D algorithm, up to 1.80x, which is observed to increase with the number of processes involved in the parallelization.”

Mateo Valero on how the MareNostrum 4 Supercomputer will Advance Science

In this video from ISC 2017, Mateo Valero from the Barcelona Supercomputing Center describes the innovations behind MareNostrum 4, the #13 supercomputer on the TOP500. “MareNostrum 4, hosted by Barcelona Supercomputing Center, is entirely aimed at generating scientific knowledge and its computer architecture has been called ‘the most diverse and interesting in the world’ by international experts. Equipped with Intel’s latest processing and networking technologies, MareNostrum provides 11.1 Petaflops of processing power to scientific production.”

How HPE is Approaching Exascale with Memory-Driven Computing

In this video from ISC 2017, Mike Vildibill describes how Hewlett Packard Enterprise describes why we need Exascale and how the company is pushing forward with Memory-Driven Computing. “At the heart of HPE’s exascale reference design is Memory-Driven Computing, an architecture that puts memory, not processing, at the center of the computing platform to realize a new level of performance and efficiency gains. HPE’s Memory-Driven Computing architecture is a scalable portfolio of technologies that Hewlett Packard Labs developed via The Machine research project. On May 16, 2017, HPE unveiled the latest prototype from this project, the world’s largest single memory computer.”
