Plasma equilibrium reconstruction acceleration method and system

Abstract

This invention discloses a method and system for accelerating plasma equilibrium reconstruction, relating to the interdisciplinary fields of nuclear fusion physics and high-performance computing. The method acquires diagnostic data measured by the diagnostic system of a tokamak device, establishes a Glad-Shafranov equilibrium equation model, constructs multiple computationally dependent kernel tasks into a computation graph, and distributes them to many-core processors for execution. A two-dimensional matrix containing plasma grid data is loaded into shared memory, and padding elements are added to the end of each row based on the column dimension and the number of memory blocks. A two-level reduction architecture is adopted in the physical error reduction stage. This scheme improves overall execution efficiency while ensuring computational accuracy and numerical consistency.
