OpenCL's use of DISPLAY for GPU conflicts with application's use of DISPLAY for GUI
Is it possible to create an `ssh -XY` connection to a headless machine running an OpenCL application using that headless machine's GPU, while tunnelling that application's GUI up the SSH connection?
The two use the same DISPLAY variable, and so far I have not found a way to tunnel X11 from the application to my laptop while at the same time using the headless GPU.
Could it be necessary to have OpenCL use a seperate environment variable for deciding which GPU display(s) to use (i.e. CL_DISPLAY) so that the GUI's DISPLAY can be set to another value?
