2022-10-27 Improvement of GPU parallel real-time equilibrium reconstruction for plasma control doi:10.57760/sciencedb.05554 en Improvements of GPU parallel real-time equilibrium reconstruction code P-EFIT are presented. P-EFIT is based on the EFIT framework, but built with the CUDA™ architecture to take advantage of massively parallel Graphical Processing Unit(GPU) cores to significantly accelerate the computation. Newly designed architecture and applied technique make P-EFIT integrate into plasma control system(PCS) as a sub-algorithm. Efficient parallel strategy and algorithms allow P-EFIT to achieve good computational performance. P-EFIT can complete one equilibrium iteration and transfer real-time diagnostics, control signals and equilibrium data in 375us with 129 × 129 spatial grid. P-EFIT has high spatial resolution, customized modules and internal current profile reconstruction for realtime plasma control in EAST.
