Characterizing the Performance of the GENE-X Code for Gyrokinetic Turbulence Simulations

SessionResearch, ACM SRC, and Doctoral Showcase Posters

DescriptionSimulating plasma turbulence in the edge region of a magnetic confinement fusion (MCF) device is crucial for identifying optimal operational scenarios for future fusion energy commercialization. GENE-X, an Eulerian electromagnetic gyrokinetic code, can simulate plasma turbulence throughout an MCF device, including the edge region. This work focuses on characterizing GENE-X's performance, such as the elapsed time during the time integration phase, memory usage, and file I/O. Two cases with different MPI decomposition schemes are analyzed using GENE-X's built-in profiler, along with profiling and monitoring tools such as IPM and Darshan. This study aims to provide a preliminary view of the HPC characteristics of the code to assist in future optimization efforts.
