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.”

Registration Opens for HPC User Forum in Princeton, NJ

Hyperion Research has posted their preliminary agenda for the upcoming HPC User Forum. The event takes place March 30 – April 1 in Princeton, New Jersey. “The HPC User Forum was established in 1999 to promote the health of the global HPC industry and address issues of common concern to users ( The organization has grown to 150 members.”

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: 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.”

Full Roundup: SC19 Booth Tour Videos from insideHPC

Now that SC19 is behind us, it’s time to gather our booth tour videos in one place. Throughout the course of the show, insideHPC talked to dozens of HPC innovators showcasing the very latest in hardware, software, and cooling technologies.

Altair PBS Works Steps Up to Exascale and the Cloud

In this video from SC19, Sam Mahalingam from Altair describes how the company is enhancing PBS Works software to ease the migration of HPC workloads to the Cloud. “Argonne National Laboratory has teamed with Altair to implement a new scheduling system that will be employed on the Aurora supercomputer, slated for delivery in 2021. PBS Works runs big — 50,000 nodes in one cluster, 10,000,000 jobs in a queue, and 1,000 concurrent active users.”

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.”
