Researchers Gear Up for Exascale at ECP Meeting in Houston

Scientists and Engineers at Berkeley Lab are busy preparing for Exascale supercomputing this week at the ECP Annual Meeting in Houston. With a full agenda running five days, LBL researchers will contribute Two Plenaries, Five Tutorials, 15 Breakouts and 20 Posters. “Sponsored by the Exascale Computing Project, the ECP Annual Meeting centers around the many technical accomplishments of our talented research teams, while providing a collaborative working forum that includes featured speakers, workshops, tutorials, and numerous planning and co-design meetings in support of integrated project understanding, team building and continued progress.”

Video: Ramping up for Exascale at the National Labs

In this video from the Exascale Computing Project, Dave Montoya from LANL describes the continuous software integration effort at DOE facilities where exascale computers will be located sometime in the next 3-4 years. “A key aspect of the Exascale Computing Project’s continuous integration activities is ensuring that the software in development for exascale can efficiently be deployed at the facilities and that it properly blends with the facilities’ many software components. As is commonly understood in the realm of high-performance computing, integration is very challenging: both the hardware and software are complex, with a huge amount of dependencies, and creating the associated essential healthy software ecosystem requires abundant testing.”

Podcast: Improving Parallel Applications with the TAU tool

In the podcast, Mike Bernhardt from ECP catches up with Sameer Shende to learn how the Performance Research Lab at the University of Oregon is helping to pave the way to Exascale. “Developers of parallel computing applications can well appreciate the Tuning and Analysis Utilities (TAU) performance evaluation tool—it helps them optimize their efforts. Sameer has worked with the TAU software for nearly two and a half decades and has released more than 200 versions of it. Whatever your application looks like, there’s a good chance that TAU can support it and help you improve your performance.”

Video: Flying through the Universe with Supercomputing Power

In this video from SC18, Mike Bernhardt from the Exascale Computing Project talked with Salman Habib of Argonne National Laboratory about cosmological computer modeling and simulation. Habib explained that the ExaSky project is focused on developing a caliber of simulation that will use the coming exascale systems at maximal power. Clearly, there will be different types of exascale machines,” he said, “and so they [DOE] want a simulation code that can use not just one type of computer, but multiple types, and with equal efficiency.”

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.”

Exascale Computing Project to go Front and Center at SC18

Over at the Exascale Computing Project, Scott Gibson has compiled an impressive list of sessions and meetups involving the ECP and all the goings on you can expect at SC18 in Dallas. “The Exascale Computing Project is accelerating delivery of a capable exascale computing ecosystem for breakthroughs in scientific discovery, energy assurance, economic competitiveness, and national security.”

Supercomputing Turbine Energy with the ExaWind Project

ECP’s ExaWind project aims to advance the fundamental comprehension of whole wind plant performance by examining wake formation, the impacts of complex terrain, and the effects of turbine-turbine wake interactions. When validated by targeted experiments, the predictive physics-based high-fidelity computational models at the center of the ExaWind project, and the new knowledge derived from their solutions, provide an effective path to optimizing wind plants.

Big Data over Big Distance: Zettar Moves a Petabyte over 5000 Miles in 29 Hours

Today AIC announced a world-record in data transfer: one petabyte in 29 hours encrypted data transfer, with data integrity checksum unconditionally enabled, over a distance of 5000 miles. The average transfer rate is 75Gbps, or 94% utilization of the available bandwidth of 80Gbps. “Even with massive amounts of data, this test confirmed once more that it’s completely feasible to carry out long distance, fully encrypted and checksum-ed data transfer at nearly the line-rate, over a shared and production network.”

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.”

Industry HPC Trends & Advocacy

David Kepczynski from GE gave this talk at the HPC User Forum in Detroit. “David Kepczynski from GE Global Research was recently apponted as the new chair of the ECP Industry Council, an external advisory group of executives from some of the nation’s most prominent companies with a collaborative interest in bringing the potential of exascale computing to a wide range of industry segments.”
