Dynamic Optimization Workflow for Gyrokinetic Stability and Transport
E. A. Belli, J. Larson, J. Candy +1
A dynamic optimization workflow for linear gyrokinetic stability that couples the gyrokinetic code CGYRO with the libEnsemble framework for ensemble management has been developed.…
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…
Flexible, integrated modeling of tokamak stability, transport, equilibrium, and pedestal physics
B. C. Lyons, J. McClenaghan, T. Slendebroek +15
The STEP (Stability, Transport, Equilibrium, and Pedestal) integrated-modeling tool has been developed in OMFIT to predict stable, tokamak equilibria self-consistently with core-tr…
Microtearding mode study in NSTX using machine learning enhanced reduced model
Max T. Curie, Joel Larakers, Jason Parisi +18
This article presents a survey of NSTX cases to study the microtearing mode (MTM) stabilities using the newly developed global reduced model for Slab-Like Microtearing modes (SLiM)…
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…
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…
