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.”

Podcast: Sciencetown Investigates Extreme Computing at SC19

In this Sciencetown podcast, we follow experts from around the world to the epicenter of supercomputing – the annual, North American supercomputing conference or SC19. We ask them to weigh in on how the future of computers, artificial intelligence, machine learning and more are coming together to shape the way we explore and understand our world.

Podcast: Will the ExaSky Project be First to Reach Exascale?

In this Lets Talk Exascale podcast, Katrin Heitmann from Argonne describes how the ExaSky project may be one of the first applications to reach exascale levels of performance. “Our current challenge problem is designed to run across the full machine [on both Aurora and Frontier], and doing so on a new machine is always difficult,” Heitmann said. “We know from experience, having been first users in the past on Roadrunner, Mira, Titan, and Summit; and each of them had unique hurdles when the machine hit the floor.”

Podcast: PSIP Brings Software Development teams together at the Exascale Computing Project

In this Lets Talk Exascale podcast, Elaine Raybourn from Sandia National Laboratories decribes how Productivity Sustainability Improvement Planning (PSIP) is bringing software development teams together at the Exascale Computing Project. PSIP brings software development activities together and enables partnerships and the adoption of best practices across aggregate teams.

Podcast: Software Deployment and Continuous Integration for Exascale

In this Let’s Talk Exascale podcast,  Ryan Adamson from Oak Ridge National Laboratory describes how his role at the Exascale Computing Project revolves around software deployment and continuous integration at DOE facilities. “Each of the scientific applications that we have depends on libraries and underlying vendor software,” Adamson said. “So managing dependencies and versions of all of these different components can be a nightmare.”

Podcast: Optimizing Math Libraries to Prepare Applications for Exascale

In this episode of Let’s Talk Exascale, Ulrike Meier Yang of LLNL describes the xSDK4ECP and hypre projects within the Exascale Computing Project. The increased number of libraries that exascale will need presents challenges. “The libraries are harder to build in combination, involving many variations of compilers and architectures, and require a lot of testing for new xSDK releases.”

An Alternative to OpenMP and an On-Ramp to Future C++ Standards

In this edition of Let’s Talk Exascale, Christian Trott of Sandia National Laboratories shares insights about Kokkos, a programming model for numerous Exascale Computing Project applications. “Kokkos is a programming model being developed to deliver a widely usable alternative to programming in OpenMP. It is expected to be easier to use and provide a higher degree of performance portability, while integrating better into C++ codes.”

Podcast: Developing Multiprecision Algorithms with the Ginkgo Library Project

In this episode of Let’s Talk Exascale, Hartwig Anzt from the University of Tennessee describes how the ECP Ginkgo Library Project is developing a vision for multiprecision algorithms. “Anything reducing the data transfer volume while still communicating the information can help make use of the software more efficient. Benefits are available even if the decreased data transfer volume comes at the cost of additional operations.”

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.”

Podcast: SCR Scalable Checkpoint/Restart Paves the Way for Exascale

A software product called the Scalable Checkpoint/Restart (SCR) Framework 2.0 recently won an R&D 100 Award. In this episode, Elsa Gonsiorowski and Kathryn Mohror of LLNL discuss what SCR does, the challenges involved in creating it, and the impact it is expected to have in HPC. “SCR enables HPC simulations to take advantage of hierarchical storage systems, without complex code modifications. With SCR, the input/output (I/O) performance of scientific simulations can be improved by orders of magnitude.”
