Opencl reduction operation performance
WebOpenCL Reduction on the ZYNQ The ZYNQ is not a GPU Bo Joel Svensson [email protected] 1 Introduction It is well known that OpenCL, while being … Weboperations are required. Finally, each OpenCL kernel launch requires the specification of local and global work sizes. We restrict the choice of local work sizes to powers of two up to a value of 512, because other workgroup sizes are either not well-suited for parallel reduction operations such as inner products, or exhaust the available ...
