This tutorial rents a 2080ti, 3.7 multi-frame mirror.

Add ali source of nvidia-cuda

 curl -fsSL https://mirrors.aliyun.com/nvidia-cuda/ubuntu1804/x86_64/7fa2af80.pub | apt-key add -
echo "deb https://mirrors.aliyun.com/nvidia-cuda/ubuntu1804/x86_64/ /" > /etc/apt/sources.list.d/cuda.list
apt update

Verify that the correct link is released

 cat nvidia.icd
ll /usr/lib/x86_64-linux-gnu/libnvidia-opencl.so.1

test opencl

Contents of clGetPlatformIDs.c

 #include <stdio.h>
#include <CL/opencl.h>

int main(int argc, char **argv)
{
    int status;
    cl_uint n_platform;

    status = clGetPlatformIDs(0, NULL, &n_platform);

     if(status != CL_SUCCESS)
    {
    fprintf(stderr, "no platforms %d\n", status);
    return -1;
    } else
    {
    fprintf(stderr, "number of CL platforms %d\n", n_platform);
    return 0;
    }
}

Enter the solution, my folder here is 22, you can follow your own habits

 cd /22
ls
gcc clGetPlatformIDs.c -lOpenCL -o main
chmod +x main
./main 

The number of CL platforms 1 appears, and the installation and testing are complete
