Abstract

The advent of GPU hardware and associated software libraries for scientific computing renders possible acceleration of parallelisable problems by a typical factor of 10-100. We present the first GPU-accelerated and open source image reconstruction software for optical/infrared interferometry, making use of the OpenCL library. Finally we evaluate how this improvement in speed may translate in terms of improvement in image reconstruction quality for currently computationnally intensive algorithms.
