Podcast: A Codebase for Deep Learning Supercomputers to Fight Cancer

In this Let’s Talk Exascale podcast, Gina Tourassi from ORNL describes how the CANDLE project is setting the stage to fight cancer with the power of Exascale computing. “Basically, as we are leveraging supercomputing and artificial intelligence to accelerate cancer research, we are also seeing how we can drive the next generation of supercomputing.”

ORNL Tests Arm-based Wombat Platform with NVIDIA GPUs

Researchers at ORNL are trying out their HPC codes on Wombat, a test bed cluster based on production Marvell ThunderX2 CPUs and NVIDIA V100 GPUs. The small cluster provides a platform for testing NVIDIA’s new CUDA software stack purpose-built for Arm CPU systems. “Eight teams successfully ported their codes to the new system in the days leading up to SC19. In less than 2 weeks, eight codes in a variety of scientific domains were running smoothly on Wombat.”

ORNL Researchers Develop Quantum Chemistry Simulation Benchmark

Researchers at the Department of Energy’s Oak Ridge National Laboratory have developed a quantum chemistry simulation benchmark to evaluate the performance of quantum devices and guide the development of applications for future quantum computers. “This work is a critical step toward a universal benchmark to measure the performance of quantum computers, much like the LINPACK metric is used to judge the fastest classical computers in the world.”

Simulating SKA Telescope’s Massive Dataflow using the Summit Supercomputer

Researchers are using the Summit Supercomputer at ORNL to simulate the massive dataflow of the future SKA telescope. “The SKA simulation on Summit marks the first time radio astronomy data have been processed at such a large scale and proves that scientists have the expertise, software tools, and computing resources that will be necessary to process and understand real data from the SKA.”

The Coming Age of Extreme Heterogeneity in HPC

Jeffrey Vetter from ORNL gave this talk at ATPESC 2019. “In this talk, I’m going to cover some of the high-level trends guiding our industry. Moore’s Law as we know it is definitely ending for either economic or technical reasons by 2025. Our community must aggressively explore emerging technologies now!”

Podcast: UnifyFS Software Project steps up to Exascale

In this Let’s Talk Exascale podcast, Kathryn Mohror LLNL and Sarp Oral of ORNL provide an update ECP’s ExaIO project and UnifyFS. “UnifyFS can provide ECP applications performance-portable I/O across changing storage system architectures, including the upcoming Aurora, Frontier, and El Capitan exascale machines. “It is critically important that we provide this portability so that application developers don’t need to spend their time changing their I/O code for every system.”

Tackling Turbulence on the Summit Supercomputer

Researchers at the Georgia Institute of Technology have achieved world record performance on the Summit supercomputer using a new algorithm for turbulence simulation. “The team identified the most time-intensive parts of a base CPU code and set out to design a new algorithm that would reduce the cost of these operations, push the limits of the largest problem size possible, and take advantage of the unique data-centric characteristics of Summit, the world’s most powerful and smartest supercomputer for open science.”

Cray and Fujitsu to bring Game-Changing Arm A64FX Processor to Global HPC Market

Today Cray and Fujitsu announced a partnership to offer high performance technologies for the exascale era. Under the alliance agreement, Cray is developing the first-ever commercial supercomputer powered by the Fujitsu A64FX Arm-based processor with high-memory bandwidth (HBM) and supported on the proven Cray CS500 supercomputer architecture and programming environment.

Deep Learning on Summit Supercomputer Powers Insights for Nuclear Waste Remediation

A research collaboration between LBNL, PNNL, Brown University, and NVIDIA has achieved exaflop (half-precision) performance on the Summit supercomputer with a deep learning application used to model subsurface flow in the study of nuclear waste remediation. Their achievement, which will be presented during the “Deep Learning on Supercomputers” workshop at SC19, demonstrates the promise of physics-informed generative adversarial networks (GANs) for analyzing complex, large-scale science problems.

SC19 to Host BoF Meeting on Americas HPC Collaboration

SC19 will host a BoF Meeting on Americas HPC Collaboration. This third BoF Americas HPC Collaboration seeks to showcase collaboration opportunities and experiences between different HPC Networks and Laboratories from countries of the American continent. “The goal of this BoF is to show the current state of the art in continental collaboration in HPC, latest developments of regional collaborative networks and, to update the roadmap for the next two years for the Americas HPC partnerships.”
