CATAPULT: A CUDA-Accelerated Timestepper for Alpha Particles Using Local Tricubics
Michael Czekanski, Alexey R. Knyazev, David Bindel +1
We introduce a CUDA-Accelerated Timestepper for Alpha Particles Using Local Tricubics (CATAPULT) for use in Monte Carlo calculations of alpha particle confinement in stellarators.…
