WebIn OpenCL 1.2 and earlier, images were qualified with the “__read_only” and __write_only” qualifiers. In the OpenCL 2.0, images can be qualified with a “__read_write” qualifier, and copy the output to the input buffer. This reduces the number of resources that are needed. Since OpenCL 1.2 images are either read_only or write_image. WebOpenCL implementations are allowed to cache the buffer contents pointed to by host_ptr in device memory. This cached copy can be used when kernels are executed on a device. …
