Has anybody successfully resolved the issue:

Run cuda code and find following error: “NVIDIA: could not open the device file /dev/nvidiactl (No such file or directory).”

Tried to run the script provided by the previous note below and got the error “fix: line 9: /etc/init.d/functions: No such file or directory”.

=> “http://forums.nvidia.com/lofiversion/index.php?t52629.html”

The environment is S870 with SUSE 10.

Thanks in advance!
