    Share OpenCL buffers between processes

    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.

    Re: Share OpenCL buffers between processes

    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.
