deviceQuery, CUDA Driver = CUDART, CUDA Driver Version = 8.0, CUDA Runtime Version = 8.0, NumDevs = 1, Device0 = GeForce GTX 1080
Result = PASS

*deviceQueryを使用するためには以下の手順を踏む必要があります。
１．/usr/local/cuda/binにあるcuda-install-samples.shを実行
２．/usr/local/cuda/bin/NVIDIA_CUDA-xx_Samples/1_Utilities/deviceQueryに移動し、makeを実行
３．/usr/local/cuda/bin/NVIDIA_CUDA-xx_Samples/1_Utilities/deviceQueryにPATHを通す

他にもこんなコマンドあるよというのがあれば教えてください
