CUDA测试

1、设置环境变量

    export PATH=/usr/local/cuda-10.0/bin:$PATH
    export LD_LIBRARY_PATH=/usr/local/cuda-10.0/lib64:$LD_LIBRARY_PATH

2、nvcc -V查看版本，注意V是大写

     root@nvidia-desktop:/# nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Mon_Mar_11_22:13:24_CDT_2019
Cuda compilation tools, release 10.0, V10.0.326

3、进入到Samples目录，sudo make

4、进入/usr/local/cuda/samples/bin/aarch64/linux/release目录，sudo ./deviceQuery和sudo ./bandwidthTest测试成功

   

root@nvidia-desktop:/usr/local/cuda/samples/bin/aarch64/linux/release# sudo ./deviceQuery
./deviceQuery Starting...
