Optimization and Portability of a Fusion OpenACC-based FORTRAN HPC Code from NVIDIA to AMD GPUs
Igor Sfiligoi, Emily A. Belli, Jeff Candy +1
NVIDIA has been the main provider of GPU hardware in HPC systems for over a decade. Most applications that benefit from GPUs have thus been developed and optimized for the NVIDIA s…
Elevating zero dimensional global scaling predictions to self-consistent theory-based simulations
Tim Slendebroek, Joseph McClenaghan, Orso Meneghini +5
We have developed an innovative workflow, STEP-0D, within the OMFIT integrated modelling framework. Through systematic validation against the International Tokamak Physics Activity…
Comparing single-node and multi-node performance of an important fusion HPC code benchmark
Emily A. Belli, Jeff Candy, Igor Sfiligoi +1
Fusion simulations have traditionally required the use of leadership scale High Performance Computing (HPC) resources in order to produce advances in physics. The impressive improv…
Fusion research using Azure A100 HPC instances
Igor Sfiligoi, Jeff Candy, Devarajan Subramanian
Fusion simulations have in the past required the use of leadership scale HPC resources to produce advances in physics. One such package is CGYRO, a premier multi-scale plasma turbu…
Kinetic fluid moments closure for a magnetized plasma with collisions
R. E. Waltz, F. D. Halpern, Z. Deng +1
A novel method aimed at a kinetic moments closure for a magnetized plasma with arbitrary collisionality is proposed. The intended first application is to a tokamak edge and scrape-…
Fluid moments of the Landau collision operator
Eero Hirvijoki, Manasvi Lingam, David Pfefferlé +3
One important problem in plasma physics is the lack of an accurate and complete description of Coulomb collisions in associated fluid models. To shed light on the problem, this Let…
Turbulent momentum transport due to neoclassical flows
Jungpyo Lee, Michael Barnes, Felix I Parra +2
Intrinsic toroidal rotation in a tokamak can be driven by turbulent momentum transport due to neoclassical flow effects breaking a symmetry of turbulence. In this paper we categori…
The Gaussian Radial Basis Function Method for Plasma Kinetic Theory
Eero Hirvijoki, Jeff Candy, Emily Belli +1
A fundamental macroscopic description of a magnetized plasma is the Vlasov equation supplemented by the nonlinear inverse-square force Fokker-Planck collision operator [Rosenbluth…
Turbulent transport of impurities and their effect on energy confinement
I. Pusztai, A. Mollen, T. Fulop +1
By presenting linear and nonlinear gyrokinetic studies, based on a balanced neutral beam injection deuterium discharge from the DIII-D tokamak, we demonstrate that impurities alter…
