Video: Doug Kothe Looks Ahead at The Exascale Computing Project

In this video, Doug Kothe from ORNl provides an update on the Exascale Computing Project. “With respect to progress, marrying high-risk exploratory and high-return R&D with formal project management is a formidable challenge. In January, through what is called DOE’s Independent Project Review, or IPR, process, we learned that we can indeed meet that challenge in a way that allows us to drive hard with a sense of urgency and still deliver on the essential products and solutions. In short, we passed the review with flying colors—and what’s especially encouraging is that the feedback we received tells us what we can do to improve.”

Podcast: Supercomputing the Emergence of Material Behavior

In this TACC Podcast, Chemists at the University of California, San Diego describe how they used supercomputing to design a sheet of proteins that toggle between different states of porosity and density. This is a first in biomolecular design that combined experimental studies with computation done on supercomputers. “To meet these and other computational challenges, Paesani has been awarded supercomputer allocations through XSEDE, the Extreme Science and Engineering Discovery Environment, funded by the National Science Foundation.”

Let’s Talk Exascale: Making Software Development more Efficient

In this episode of Let’s Talk Exascale, Mike Heroux from Sandia National Labs describes the Exascale Computing Project’s Software Development Kit, an organizational approach to reduce the complexity of the project management of ECP software technology. “My hope is that as we create these SDKs and bring these independently developed products together under a collaborative umbrella, that instead of saying that each of these individual products is available independently, we can start to say that an SDK is available.”

AI Podcast Looks at Recent Developments at NVIDIA Research

In this episode of the AI Podcast, Bryan Cantanzaro from NVIDIA discusses some of the latest developments at NVIDIA research. “The goal of NVIDIA research is to figure out what things are going to change the future of the company, and then build prototypes that show the company how to do that,” says Catanzaro. “And AI is a good example of that.”

Let’s Talk Exascale: Transforming Combustion Science and Technology

In this episode of Let’s Talk Exascale, Jackie Chen from Sandia National Laboratories describes the Combustion-Pele project, which uses predictive simulation for the development of cleaner-burning engines. “Almost all practical combustors operate under extremely high turbulence levels to increase the rate of combustion providing high efficiency, but there are still outstanding challenges in understanding how turbulence affects auto-ignition.”

Radio Free HPC Does the Math on pending CORAL-2 Exascale Machines

In this podcast, the Radio Free HPC team takes a look at daunting performance targets for the DOE’s CORAL-2 RFP for Exascale Computers. “So, 1.5 million TeraFlops divided by 7.8 Teraflops per GPU is how many individual accelerators you need, and that’s 192,307. Now, multiply that by 300 watts per accelerator, and it is clear we are going to need something all-new to get where we want to go.”

Let’s Talk Exascale: Thom Dunning on Molecular Modeling with NWCHEMEX

In this edition of Let’s Talk Exascale, Thom Dunning from the University of Washington describes the software effort underway to for molecular modeling at exascale with NWCHEMEX. “To date, our work is focused on the redesign of Northwest Chem, but we’ve also explored a number of alternate strategies for implementing the overall redesign as well as the redesign of the algorithms, and this work required access to the ECP computing allocations.”

New Paper: A Survey of Techniques for Dynamic Branch Prediction

Branch predictor (BP) is an essential component in modern processors since high BP accuracy can improve performance and reduce energy. However, reducing latency and storage overhead of BP while maintaining high accuracy presents significant challenges. Especially in light of Spectre attack, which arises due to speculative execution such as branch prediction, a relook on branch predictors is very important. In this paper, we present a survey of dynamic branch prediction techniques. We review two-level BPs, neural-BPs, hybrid BPs and techniques for improving BP accuracy and reducing implementation overheads.

Podcast: TACC Powers Deep Earth Imaging

“In this TACC Podcast, Ross Maguire and Jeroen Ritsema of the University of Michigan describe how supercomputer simulations of volcanos show how mantle plumes form and how they rise from Earth’s mantle. What’s more, the researchers say their work could guide future experiments with seismic imaging and help get to the bottom of mysteries like the origin of Hawaii’s volcanos.”

Radio Free HPC Looks at New USA Supercomputing Map

In this podcast, the Radio Free HPC team looks at the new interactive USA Supercomputing Map from Hyperion Research. “As part of the discussion, Rich recaps Hyperion’s recent HPC User Forum in Tucson. The event featured an extended session on Quantum Computing with presentations by D-Wave Systems, Google, IBM, Intel, Microsoft, NIST, and Rigetti Computing.”
