NRrange size, offsets and workgroup size

Hi, In situations in which you don't want to compute on all the elements in an 2d-array/opencl buffer. On the FPGA would I be better launching the exact amount of work items required to proces...

Thanks for the quick response BadOmen.

re the last question. I guess I'm just trying to understand what the tradeoffs / benefits are from specifying different sized workgroups. I can understand why you would vary this for the GPU architecture to fit the optimal block on each sub-processor/core etc. However its unclear to me how this maps to the FPGA. Grateful if you could elaborate.
