Web2 de ago. de 2024 · A two-dimensional problem would be some computation on an image. In the case of an 1024x768 image, the NDRange size Gx would be 1024 and the NDRange size Gy would be 768. This assumes, that there are 1024x768 work items out there to process each pixel of that image. The NDRange size then equals 1024x768.
