Web4 de jun. de 2024 · Since this is a buffer to buffer copy, all parameters are in bytes. As with the OpenCL standard clEnqueueCopyBufferRectfunction, copying begins at the source offset (src_origin) and destination offset (dst_origin). Each byte of the region's width is copied from the source offset to the destination offset. http://man.opencl.org/clCreateBuffer.html
Web16 de set. de 2014 · Creating Buffers with clCreateBuffer () One use case for OpenCL is when memory is already populated on the host and you want the device to read this data. In this case use the flag CL_MEM_USE_HOST_PTR to create the buffer. This may be the case when we are using OpenCL with existing codebases. 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.
