Opencl buffer
Web2 de nov. de 2010 · OpenCL 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. I had an argument with a co-worker who thought that this implies that whenever a device is not executing a kernel using the buffer, the host memory is … WebNote that OpenCL 2.0 introduces SVM buffer. SVM is generally not supported for image object s. To create an image object from an SVM buffer, pass the SVM buffer as a pointer to the clCreateBuffer function as its host_ptr argument with the CL_MEM_USE_HOST_PTR flag. In this case clCreateBuffer succeeds and returns a valid non-zero buffer object.

Web16 de jun. de 2011 · You could create a CL 3D image object that is shared with GL as I described above, then use OpenCL to write data into a separate CL buffer object. Finally, clEnqueueCopyBufferToImage () would copy the data from the buffer to the GL texture. The downside is that it does a copy. The upside is that all the operations occur in device … Webcommand_queue and buffer must be created with the same OpenCL context. buffer. Refers to a valid buffer object. blocking_write. Indicates if the write operations are blocking or nonblocking. If blocking_write is CL_TRUE, the OpenCL implementation copies the data referred to by ptr and enqueues the write operation in the command-queue.

I have just testet my code with image2d and buffer objects. I have noticed that buffers are twice as fast as images in my case (1.2k² image, 200² Filter).
WebTo manage data in OpenCL, buffers or images that represent an abstract view of the device memory must be created, and functions are used to read from, write to, or copy with the device memory.

OpenCL provides a mechanism to map a region of a buffer directly into host memory instead of using the clEnqueue [Read Write]Buffer functions. These mapped regions can be returned to the application.
