processing element and work items

Thanks for the answer. But I mean to ask the hardware (processing elements) that is generated on the FPGA.

From the aoc --report, I can see, if i maintain the same block_size, butt change the simd_work_item from 2 to 1, the hardware resources costed will be less as well. So I am guessing more simd_work_item means more hardware resource usage.

Thanks.

Number of work-items that will launched will be 16*32.

That is because the compiler will vectorize the work-items on the local_id(0) dimension; each work-item will do the work of two work-items. Hence, half the number of work-items on this dimension will be launched.
