View Full Version : Share OpenCL buffers between processes

10-05-2010, 12:15 PM
Suggestion for a next release: a way to share OpenCL buffers between processes, that is for instance:

- allocate a buffer with clCreateBuffer with a memory region on the GPU

- send the resulting cl_mem object to another process

- use the cl_mem object from the second process to access the same memory region in the GPU.

Memory objects are associated with an OpenCL context which is created by a thread running in a process. Therefore, the specification does not provide a way to share CL buffers between processes.
