Hello everybody, I have a pyopencl application passing along pointers for the memory buffers and the context to a C opencl program which is called within the same python script. This worked perfectly in a mockup dummy project, but actually implementing it within my actual library has surfaced a roadblock. Taking the pointer from pyopencl and passing it along to my opencl code works perfectly fine and doesn't break anything (using copies of buffers initialised in the C opencl code itself). Sharing the buffers to circumvent these extra memory operations breaks the program. The buffers initialised in opencl are initialised as both read and write buffers.
My clFinish() with just my kernel queued returns an error 36: INVALID_COMMAND_QUEUE. I've also tried sharing the command queue from pyopencl; this doesn't change anything. I've additionally checked both dimensionality and dtype/nbytes of my buffers. The ones initialised in (and passed on from) pyopencl are in this sense identical to those I made in my C code itself, in the test that does not share the buffers (which works). I couldn't find a solution to this issue so far, but hope that you may be able to help me. In any way, thank you for your time!
