Exclusive compute mode with OpenCL+NVidia
- by lokli
Hi,
I have a question to exclusive compute mode with NVidia+OpenCL.
I can set up exclusive compute mode (page 74 from cuda programming guide 3.0) with nvidia-smi on a nvidia-gpu . that means, only one program can compute on gpu.
cuda runtime schedules than app automatically.
but I have a problem with opencl-programs in this case:
if one application runs on a gpu with setted exclusive compute mode and second opencl-program calls clGetDeviceInfo(..., CL_DEVICE_AVAILABLE, ...) with the same GPU is the result == CL_TRUE. After that if opencl-app tries to create a context on this device, than crashes the running app (both).
How can i find out an available GPU with OpenCL?
Thanks.
