GPU Accelerated Simulations and Real-time Control of the E-ELT Adaptive Optics Systems
Abstract:
Adaptive Optics (AO) is an instrumental technique for the correction of dynamically evolving aberrations in optical systems, used on astronomical telescopes to compensate, in real-time, for atmospheric turbulence. Our team has developped a simulation code based on YoGA, an original binding between Yorick, an interpreted programming language and CUDA. Using this code, speedups of 10x are obtained as compared to currently available CPU codes. We will present the various features of the code and its performance for various system dimensioning and GPUs. Additionally, we will present profiles of a GPU-based AO real-time controller simulator demonstrating performance compatible with real-time operations.
