CPU-GPU Collaboration for Output Quality Monitoring
Mehrzad Samadi, Scott A. Mahlke · 2014
In this paper, we proposed a new low overhead collabora-tive technique of output quality monitoring for approximate computing on GPUs. In this technique, the CPU is respon-sible for performing quality monitoring while the GPU exe-cutes approximate kernels. For two image processing appli-cations, we showed that this technique outperforms previous quality monitoring techniques. 1.
