Hello Sir,
Thank you for the description. I got a rough idea at first, but this makes
it a lot clear :)
Regarding the OpenGL issue:
I am using CentOS 6 with NVIDIA GPU. I have installed CUDA. The and the
'devicequery' code works fine, which makes me think that CUDA, and hence
OpenCL, is installed correctly. The only issue is, for the X server, the
"GLX missing" pops up because missing "xorg.conf" file. Generating the file
using "nvidia-config" does the work, but after restart, the Xserver fails
to launch. This had been the issue with many, and I am not able to find any
working solution. If there is a way from which I can run the OpenCL code
without the involvement of OpenGL, it would be the fastest solution.
Regards
