I get the error “Unable to profile application. Unknown nvprof return value: 19” when I am trying to profile the application file generated by the CUDA program.
I tried using the “Build” (Hammer icon) first and then run, as mentioned in other topics. However, in vain.
I have a hunch that it is due to other version of nvprof present in the system. I happen to have both CUDA 5.5 and 6.5.
