Two questions:
1) Do you see /dev/nvidia{0,1,2,3}?
2) Do you have sufficient permissions to access them from the account in
which you run your code?
About your issue with clCreateSubDevices: To fully rebuild, you may need
to 'rm -Rf build' before rebuilding, within the source directory.
Hope that helps,
Andreas
