This will print all available information about all OpenCL platforms on the system and the devices they expose.
Alternatively, if you do not want to add your user to the group mentioned above, you can use sudo
:
sudo /usr/bin/clinfo -l
In case the number of platforms is equal to 0 you need to Install OpenCL Drivers On Ubuntu.
