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.”

Podcast: Inventing the Future with AI for Science

In this Sound of Science podcast, researchers from ORNL dispel some of those myths and discuss how AI is transforming cancer research, manufacturing and plant biology. “Artificial intelligence is no longer just a subject of science fiction. From personal assistants to self-driving cars, AI is revolutionizing everyday life. While AI may be more prevalent these days, there are still a lot of misconceptions about what it is and what it isn’t.”

How Data and Computing Can Change Medicine in the Exascale Era

In this video, Gina Tourassi from ORNL explains how data and computing is changing medicine. “Exascale computing infrastructure such as Frontier will be the paradigm shift because we can bring all of the data together and analyze it in a time efficient way,” said Tourassi.

Supercomputing the Building Blocks of the Universe

In this special guest feature, ORNL profiles researcher Gaute Hagen, who uses the Summit supercomputer to model scientifically interesting atomic nuclei. “A central question he is trying to answer is: what is the size of a nucleus? The difference between the radii of neutron and proton distributions—called the “neutron skin”— has implications for the equation-of-state of neutron matter and neutron stars.”

Supercomputing Structures of Intrinsically Disordered Proteins

Researchers using the Titan supercomputer at ORNL have created the most accurate 3D model yet of an intrinsically disordered protein, revealing the ensemble of its atomic-level structures. The combination of neutron scattering experiments and simulation is very powerful,” Petridis said. “Validation of the simulations by comparison to neutron scattering experiments is essential to have confidence in the simulation results. The validated simulations can then provide detailed information that is not directly obtained by experiments.”

First Annual Exascale Day on 10/18 to Celebrate Supercomputing Discoveries

“Exascale Day celebrates the scientists and researchers who make breakthrough discoveries with the help of some of the fastest supercomputers in the world. Exascale Day celebrates those who keep asking what if, why not, and what’s next — with the advanced technology to attain the answers. The founding organizations have established National Exascale Day as a registered holiday to be celebrated annually on October 18 (1018).”

How the Results of Summit and Sierra are Influencing Exascale

Al Geist from ORNL gave this talk at the HPC User Forum. “Two DOE national laboratories are now home to the fastest supercomputers in the world, according to the TOP500 List, a semiannual ranking of the world’s fastest computing systems. The IBM Summit system at Oak Ridge National Laboratory is currently ranked number one, while Lawrence Livermore National Laboratory’s IBM Sierra system has climbed to the number two spot.”

Exascale Computing Project Update

Doug Kothe from the Exascale Computing Project gave this talk at the HPC User Forum. “The Exascale Computing Project (ECP) is focused on accelerating the delivery of a capable exascale computing ecosystem that delivers 50 times more computational science and data analytic application power than possible with DOE HPC systems such as Titan (ORNL) and Sequoia (LLNL). With the goal to launch a US exascale ecosystem by 2021, the ECP will have profound effects on the American people and the world.”
