L.S., I encouter recently the "Cuda Error # 3" with a Quadro P4000 when running rtkfdk, but I am not sure if the cause is the same as Tao's problem. CUDA_CHECK() marks Driver API error with a "#" whereas Runtime API error with a ":", so it is CUresult 3 (CUDA_ERROR_NOT_INITIALIZED). Indeed when I add CUDA_CHECK to cuInit(0) in itkCudaContextManager.cxx I already got an CUresult 100 (CUDA_ERROR_NO_DEVICE) here. In the same itkCudaContextManager.cxx file, itk::CudaGetAvailableDevices (which calls Runtime API) works well, so only Driver API doesn't work properly. The same build works fine with a Tesla P40.
I don't have time to investigate further but I found on my computer a previous build based on commit 5717b6d02675ee10f03200038566f06dfcc2ad19 in May 2018 doesn't have this issue with the Quadro card. So I guess it shouldn't be the problem of the card or the driver, but a problem induced by a later commit.
