GTX 1070, GTX 960, GT 640M의 cudaGetDeviceProperties 출력 결과
그냥 기록 차원에서 남깁니다. ^^
우선, CUDA 사양을 cudaGetDeviceProperties API를 통해서 구하는 것이 가능하지만 CUDA SDK 설치 시 /extras/demo_suite 폴더의 deviceQuery.exe 프로그램을 이용하는 것이 편리합니다.
다음은, GTX 1070 시스템에서의 출력 결과이고,

참고로, Hyper-V의 RemoteFX 환경에서는 (당연하지만) 다음과 같이 CUDA 호환 장비를 찾을 수 없다는 메시지가 나옵니다.
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 35
-> CUDA driver version is insufficient for CUDA runtime version
Result = FAIL
