Web7 de abr. de 2010 · Unlike regular C where you can spend a lot of time writing outer loops and launching worker threads for subparts of your problem, OpenCL does it for you. We'll see how that works shortly. QtOpenCL The QtOpenCL library wraps the … WebThe datapath of a loop within a single work-item kernel can contain multiple iterations in flight. 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.
