Video: ExaAM – Transforming Additive Manufacturing through Exascale Simulation

In this video from the HPC User Forum in Detroit, John Turner, Oak Ridge National Laboratory presents: ExaAM – Transforming Additive Manufacturing through Exascale Simulation. “The goal of ExaAM is to develop an AM simulator that will give researchers a tool to determine the best method to print parts with complex geometries and site-specific properties, complemented by real-time, in situ process visualization, analyses and optimization. Coupled with a modern computer-aided design tool, the simulator will allow the routine use of AM to build unique, qualifiable metal alloy parts across many industries relevant to DOE.”

Interview: Dan Jacobson from ORNL on Why PASC19 will be The Show to Attend Next Year

In this video from PASC18, Dan Jacobson from ORNL describes the highlights from the conference and why scientists and engineers should consider attending PASC19 in Zurich. “Next year, PASC19 happens the week before the ISC 2019 conference in Germany. Be sure to catch both shows!”

Podcast: From Here to Ai with Jack Wells from Oak Ridge

In this Conversations with Dez podcast, Dez Blanchfield sits down with Jack Wells from ORNL to talk about about his personal & professional life journey, his role at Oak Ridge National Lab, how Artificial Intelligence is being deployed & leveraged in HPC, and the role IBM’s POWER9 solution is playing in supporting Oak Ridge and its mission. Jack Wells is the Director of Science for the Oak Ridge Leadership Computing Facility.

Characterizing Faults, Errors and Failures in Extreme-Scale Computing Systems

Christian Engelmann from ORNL gave this talk at PASC18. “Building a reliable supercomputer that achieves the expected performance within a given cost budget and providing efficiency and correctness during operation in the presence of faults, errors, and failures requires a full understanding of the resilience problem. The Catalog project develops a fault taxonomy, catalog and models that capture the observed and inferred conditions in current supercomputers and extrapolates this knowledge to future-generation systems. To date, the Catalog project has analyzed billions of node hours of system logs from supercomputers at Oak Ridge National Laboratory and Argonne National Laboratory. This talk provides an overview of our findings and lessons learned.”

Video: Intro to OpenMP

In this video, Markus Eisenbach and Dmitry Liakh from ORNL present: Intro to OpenMP, Part 1. “This video was recorded as part of the “Introduction to HPC” workshop that took place at ORNL from June 26-28. This is video 1 of 2, which gives a brief overview of parallel computing with OpenMP.”

InfiniBand Powers World’s Fastest Supercomputer

Today the InfiniBand Trade Association (IBTA) announced that the latest TOP500 List results that report the world’s new fastest supercomputer, Oak Ridge National Laboratory’s Summit system, is accelerated by InfiniBand EDR. InfiniBand now powers the top three and four of the top five systems. The latest rankings underscore InfiniBand’s continued position as the interconnect of choice for the industry’s most demanding high performance computing (HPC) platforms. “As the makeup of the world’s fastest supercomputers evolve to include more non-HPC systems such as cloud and hyperscale, the IBTA remains confident in the InfiniBand Architecture’s flexibility to support the increasing variety of demanding deployments,” said Bill Lee, IBTA Marketing Working Group Co-Chair. “As evident in the latest TOP500 List, the reinforced position of InfiniBand among the most powerful HPC systems and growing prominence of RoCE-capable non-HPC platforms demonstrate the technology’s unparalleled performance capabilities across a diverse set of applications.”

OpenACC Helps Scientists Port their code at the Center for Application Readiness (CARR)

In this video, Jack Wells from the Oak Ridge Leadership Computing Facility and Duncan Poole from NVIDIA describe how OpenACC enabled them to port their codes to the new Summit supercomputer. “In preparation for next-generation supercomputer Summit, the Oak Ridge Leadership Computing Facility (OLCF) selected 13 partnership projects into its Center for Accelerated Application Readiness (CAAR) program. A collaborative effort of application development teams and staff from the OLCF Scientific Computing group, CAAR is focused on redesigning, porting, and optimizing application codes for Summit’s hybrid CPU–GPU architecture.”

Univa Deploys Million-core Grid Engine Cluster on AWS

To demonstrate the unique ability to run very large enterprise HPC clusters and workloads, Univa leveraged AWS to deploy 1,015,022 cores in a single Univa Grid Engine cluster to showcase the advantages of running large-scale electronic design automation (EDA) workloads in the cloud. The cluster was built in approximately 2.5 hours using Navops Launch automation and comprised more than 55,000 AWS instances in 3 availability zones, 16 different instance types and leveraged AWS Spot Fleet technology to maximize the rate at which Amazon EC2 hosts were launched while enabling capacity and costs to be managed according to policy.

Let’s Talk Exascale: Optimizing I/O at the ADIOS Project

In this episode of Let’s Talk Exascale, researchers from the ADIOS project describe how they are optimizing I/O on exascale architectures and making the code easily maintainable, sustainable, and extensible, while ensuring its performance and scalability. “The Adaptable I/O System (ADIOS) project in the ECP supports exascale applications by addressing their data management and in situ analysis needs.”

Video: Researchers Step Up with the New Summit Supercomputer

“The biggest problems in science require supercomputers of unprecedented capability. That’s why the ORNL launched Summit, a system 8 times more powerful than their previous top-ranked system, Titan. Summit is providing scientists with incredible computing power to solve challenges in energy, artificial intelligence, human health, and other research areas, that were simply out of reach until now. These discoveries will help shape our understanding of the universe, bolster US economic competitiveness, and contribute to a better future.”
