Web1 de fev. de 2013 · Opencl spends in 5 time more then a cpu loop. Is it ok or something is wrong? If i have more complicated function(c[iGID] = a[iGID] + sqrt(b[iGID] * b[iGID]);) than difference is much bigger(in 150 times) :)Thank you.

This behavior is different from a loop within an NDRange kernel in that an NDRange kernel's loop contains multiple work-items (rather than loop iterations) in flight. In an optimally pipelined loop, a new loop iteration is launched every clock cycle.

Web5.1 Unrolling loops. According to Intel: The OpenCL kernel performs one loop iteration of each work-item per clock cycle. With sufficient hardware resources, you can increase kernel performance by unrolling the loop, which decreases the number of iterations that the kernel executes. To unroll a loop, add a #pragma unroll directive to the main loop.
