This work is carried out within a research collaboration with the Astronomical Observatory of Arcetri (Florence, Italy) aimed at the development of a parallel version of the adaptive optics simulation software named CAOS (Code for Adaptive Optics System). CAOS is currently used at the Arcetri Observatory to simulate the behaviour of an adaptive optic system, from the atmospheric turbulence corruption to the subsequent adaptive correction made on the wavefronts coming from the astronomical objects onto the pupils of the ground-based telescopes. We describe the computational efforts towards the integration of the CAOS package into a high-performance computing architecture, implementing three different parallelization approaches of a fast fourier transform (FFT)-based CAOS module and discuss the performance using standard performance metrics.

Abstract
This work is carried out within a research collaboration with the Astronomical Observatory of Arcetri (Florence, Italy) aimed at the development of a parallel version of the adaptive optics simulation software named CAOS (Code for Adaptive Optics System). CAOS is currently used at the Arcetri Observatory to simulate the behaviour of an adaptive optic system, from the atmospheric turbulence corruption to the subsequent adaptive correction made on the wavefronts coming from the astronomical objects onto the pupils of the ground-based telescopes. We describe the computational efforts towards the integration of the CAOS package into a high-performance computing architecture, implementing three different parallelization approaches of a fast fourier transform (FFT)-based CAOS module and discuss the performance using standard performance metrics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
