CUDA invalid device function

I get an thrust::system::system_error invalid device function while trying to access a device vector with thrust::device_vector< int > labels_d(width*height);

In my CMakeFile I've written SET(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-gencode arch=compute_20,code=compute_20) And also tried different settings there. So I guess it has something to do with my GPU (a Quadro FX 580) and CUDA maybe a pointer to my device is wrong or something...

Does anybody have a clue on what to change to make it work?

I've managed to find out that my GPU simply is too old for arch=compute_20, and so I have to use arch=compute_11.
