    In this video from the GPU Technology Conference, Jeff Candy and Igor Sfiligoi from General Atomics present: Advancing Fusion Science with CGYRO using GPU-based Leadership Systems.

    “Learn about the science of magnetically confined plasmas to develop the predictive capability needed for a sustainable fusion energy source. Gyrokinetic simulations are one of the most useful tools for understanding fusion science. We’ll explain the CGYRO code, built by researchers at General Atomics to effectively and efficiently simulate plasma evolution over multiple scales that range from electrons to heavy ions. Fusion plasma simulations are compute- and memory-intensive and usually run on leadership-class, GPU-Accelerated HPC systems like Oak Ridge National Laboratory’s Titan and Summit. We’ll explain how we designed and implemented CGYRO to make good use of the tens of thousands of GPUs on such systems, which provide simulations that bring us closer to fusion as an abundant clean energy source. We’ll also share benchmarking results of both CPU- and GPU-Based systems.”

    General Atomics is a key partner in ITER — one of the largest scientific programs in history — which seeks to demonstrate the scientific and technological feasibility of fusion power, a potentially limitless source of clean energy.

    The ITER facility is currently being constructed in France by a consortium of 35 nations. GA is manufacturing major components for this worldwide initiative, including diagnostics systems and the Central Solenoid, the world’s largest pulsed superconducting electromagnet.

    GA’s Theory and Computational Science program advances the fundamental theoretical understanding of fusion plasmas through development and application of industry-leading computer simulations. The theory program works with DIII-D to validate models and simulations against robust experimental data.

    Award will support educational and research efforts in high-energy-density physics at MIT and four academic research partners.

    The High-Energy-Density Physics (HEDP) division of MIT’s Plasma Science and Fusion Center (PSFC), along with four other universities, has been awarded a five-year, $10 million grant to establish a Stewardship Science Academic Alliances Center of Excellence. The PSFC will be the lead partner in the center, which includes the University of Iowa; the University of Nevada at Reno; the University of Rochester; and Virginia Polytechnic Institute and State University.

    The U.S. Department of Energy’s (DOE) National Nuclear Security Administration (NNSA) award will support educational and research missions across the partners. The goal of the newly established center is to generate exceptional experimental and theoretical PhDs in HEDP and inertial confinement fusion (ICF), while addressing issues of critical interest to the Department of Energy’s NNSA and national labs.

    Officially called the Center for Advanced Nuclear Diagnostics and Platforms for Inertial ICF and HEDP at Omega, NIF and Z, the center will focus on the properties of plasma under extreme conditions of temperature, density and pressure. Center partners will collaborate closely with the Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Sandia National Laboratory, the Laboratory for Laser Energetics, and General Atomics.

    MIT’s HEDP division has a long and established history of collaboration with these labs, regularly using Laser Energetics’s 30-kilojoule OMEGA laser, Lawrence Livermore’s National Ignition Facility, and Sandia’s Z machine to pursue a wide range of research, including inertial confinement fusion, nuclear science, and laboratory astrophysics. The division has used its Accelerator Facility to develop and characterize diagnostics for these machines, and as part of the new center will pursue new diagnostic techniques for advanced research.

    HEDP division head and Center of Excellence Director Richard Petrasso acknowledges the importance of this partnership.

    “The center is about our work in inertial confinement fusion, and also in laboratory astrophysics, simulating aspects of astrophysical phenomena, such as the jetting in the crab nebula,” Petrasso says. “There is lots of interesting physics that students and staff have been observing for years. This new center allows us, with our partners, to really expand our investigations.”

    PSFC Director Dennis Whyte observed that the new center is a recognition of the HEDP division’s excellence. Thanking the team for the exceptional work, under the encouragement of the senior leadership, he said, “Your work is one of the gems of the PSFC. This division produces outstanding, unique science, and with a mission that is critical to national security.”

    Launched in 2002, the Stewardship Science Academic Alliances Centers of Excellence program emphasizes areas of research that are relevant to NNSA’s stockpile stewardship mission, and promotes the education of the next generation of highly-trained nuclear scientists and engineers.
