不幸的是NVML不提供有关设备计算能力的信息。

Unfortunately NVML doesn't provide information about device compute capability.

您需要做的是：

1. 加载手动CUDA库（应用程序不是针对libcuda链接）
   
   
   
   • 如果库中不存在，未安装CUDA驱动程序
   
   

我希望这code会有所帮助。我已经在Linux下进行测试，但稍作修改也应该在Windows下进行编译。

I hope this code will be helpful. I've tested it under Linux but with minor modifications it should also compile under Windows.

#include <cuda.h>
#include <stdio.h>

#ifdef WINDOWS
#include <Windows.h>
#else
#include <dlfcn.h>
#endif


void * loadCudaLibrary() {
#ifdef WINDOWS
    return LoadLibraryA("nvcuda.dll");
#else
    return dlopen ("libcuda.so", RTLD_NOW);
#endif
}

void (*getProcAddress(void * lib, const char *name))(void){
#ifdef WINDOWS
    return (void (*)(void)) GetProcAddress(lib, name);
#else
    return (void (*)(void)) dlsym(lib,(const char *)name);
#endif
}

int freeLibrary(void *lib)
{
#ifdef WINDOWS
    return FreeLibrary(lib);
#else
    return dlclose(lib);
#endif
}

typedef CUresult CUDAAPI (*cuInit_pt)(unsigned int Flags);
typedef CUresult CUDAAPI (*cuDeviceGetCount_pt)(int *count);
typedef CUresult CUDAAPI (*cuDeviceComputeCapability_pt)(int *major, int *minor, CUdevice dev);

int main() {
    void * cuLib;
    cuInit_pt my_cuInit = NULL;
    cuDeviceGetCount_pt my_cuDeviceGetCount = NULL;
    cuDeviceComputeCapability_pt my_cuDeviceComputeCapability = NULL;

    if ((cuLib = loadCudaLibrary()) == NULL)
        return 1; // cuda library is not present in the system

    if ((my_cuInit = (cuInit_pt) getProcAddress(cuLib, "cuInit")) == NULL)
        return 1; // sth is wrong with the library
    if ((my_cuDeviceGetCount = (cuDeviceGetCount_pt) getProcAddress(cuLib, "cuDeviceGetCount")) == NULL)
        return 1; // sth is wrong with the library
    if ((my_cuDeviceComputeCapability = (cuDeviceComputeCapability_pt) getProcAddress(cuLib, "cuDeviceComputeCapability")) == NULL)
        return 1; // sth is wrong with the library

    {
        int count, i;
        if (CUDA_SUCCESS != my_cuInit(0))
            return 1; // failed to initialize
        if (CUDA_SUCCESS != my_cuDeviceGetCount(&count))
            return 1; // failed

        for (i = 0; i < count; i++)
        {
            int major, minor;
            if (CUDA_SUCCESS != my_cuDeviceComputeCapability(&major, &minor, i))
                return 1; // failed

            printf("dev %d CUDA compute capability major %d minor %d\n", i, major, minor);
        }
    }
    freeLibrary(cuLib);
    return 0; 
}

在Linux上测试：

Test on Linux:

$ gcc -ldl main.c
$ ./a.out
dev 0 CUDA compute capability major 2 minor 0
dev 1 CUDA compute capability major 2 minor 0

测试在Linux上，没有CUDA驱动程序

Test on linux with no CUDA driver

$ ./a.out
$ echo $?
1
