Abstract
CGYRO, an Eulerian gyrokinetic solver designed and optimized for collisional, electromagnetic, multiscale fusion plasma simulation, has been ported and benchmarked on a Summit-like Power9-based system equipped with Volta GPUs. We present our experience porting the application and provide benchmark numbers obtained on the Power-based node and compare them with equivalent tests from several leadership class systems. The tested node provided the fastest single-node CGYRO runtimes we’ve measured to date.
Supported by General Atomics internal research and development funds.
