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.

How Red Hat Powers the #1 Summit Supercomputer

In this video from ISC 2018, Yan Fisher from Red Hat and Buddy Bland from ORNL discuss Summit, the world’s fastest supercomputer. Red Hat teamed with IBM, Mellanox, and NVIDIA to provide users with a new level of performance for HPC and AI workloads. ”
But the rapid innovation showcased by Summit must be consumable, and that’s where Red Hat Enterprise Linux comes in. Despite the scale, processing capability, and “intelligence” of Summit’s composition, end users interact with something they understand: Linux, in the form of the world’s leading enterprise Linux platform. Red Hat Enterprise Linux provides a common, stable basis that ties together all of this innovation.”

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.”

NVIDIA Tensor Core GPUs Accelerate World’s Fastest Supercomputers

Today NVIDIA is highlighting news that the world’s top AI supercomputers on the TOP500 are all powered by the company’s Tensor Core GPUs. The new “AI supercomputers” on the list include Summit and Sierra in the USA and the ABCI machine in Japan. “The new TOP500 list clearly shows that GPUs are the path forward for supercomputing in an era when Moore’s Law has ended,” said Ian Buck, vice president and general manager of accelerated computing at NVIDIA.

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.”

Video: Announcing Summit – World’s Fastest Supercomputer with 200 Petaflops of Performance

Today Energy Secretary Rick Perry unveiled Summit, the world’s most powerful supercomputer. Powered by IBM POWER9 processors, 27,648 NVIDIA GPUs, and Mellanox InfiniBand, the Summit supercomputer is also the first Exaop AI system on the planet. “This massive machine, powered by 27,648 of our Volta GPUs, can perform more than three exaops, or three billion billion calculations per second,” writes Ian Buck on the NVIDIA blog. “That’s more than 100 times faster than Titan, previously the fastest U.S. supercomputer, completed just five years ago. And 95 percent of that computing power comes from GPUs.”

Video: IBM Brings NVIDIA Volta to Supercharge Discoveries

In this video from GTC 2018, Adel El-Hallak from IBM describes how IBM and NVIDIA are partnering to build the largest supercomputers in the world to enable data scientists and application developers to not be limited to any device memory. Between IBM and NVIDIA, you can capitalize on the Volta 32GB memory and the entire system as a whole.

Video: Powering the Road to National HPC Leadership

Jack Wells from ORNL gave this talk at the 2018 OpenPOWER Summit. “The Summit supercomputer coming to Oak Ridge is the next leap in leadership-class computing systems for open science. Summit will have a hybrid architecture, and each node will contain multiple IBM POWER9 CPUs and NVIDIA Volta GPUs all connected together with NVIDIA’s high-speed NVLink. Each node will have over half a terabyte of coherent memory (high bandwidth memory + DDR4) addressable by all CPUs and GPUs plus 800GB of non-volatile RAM that can be used as a burst buffer or as extended memory.”

Application Readiness Projects for the Summit Supercomputer Architecture

Dr. Tjerk P. Straatsma from ORNL gave this talk at SC17. “The Center for Accelerated Application Readiness (CAAR) projects are using an Early Access Power8+/Pascal system named SummitDev to prepare for the Power9/Volta system Summit. This presentation highlights achievements on this system, and the experience of the teams that will be a valuable resource for other development teams.”
