This lecture deals with how work groups are scheduled for execution on the compute units of devices. Also explain the effects of divergence of work items within a group and its negative effect on performance. Clinical Wavefront analysisThe wave theory of light has one of its major applications in wavefront analysis. An optically perfect imaging system brings all rays from a single object point to a point f between LSST and SKA. Bob Mann. University of Edinburgh. LSST:UK Project Leader. www.lsst.ac.uk.
