work group size

Question asked by sajis997 on Mar 29, 2013

Hi forum,


I believe the OpenCL equivalent of the CUDA block is work group. in CUDA we have to explicitly define the block size and i just heard from a lecture that in OpenCL we do not need to define the work group size and the most optimum is decided by the OpenCL itself. Is that really true ?



I believe that OpenCL still provides with the provision to define it .



How about some more discussion over this issue?
