Question

我试图在我的电脑上开始使用CUDA 6.5。我有WIN 8.1，VS 2013终极版，VGA nvidia NVS 300.一切看起来都不错，构建过程成功完成，但是当我运行程序时，内核不会执行。例如，以下简单代码：

#include "crt/host_runtime.h"
#include <cuda.h>
#include <stdio.h>
#include "cuda.h"
#include "cuda_runtime.h"
#include "device_launch_parameters.h"

__global__ void add(int a, int b, int *c) {*c = a + b;}

int main() {
    int c;
    int *dev_c;
    cudaMalloc((void**)&dev_c, sizeof(int));
    add << <1, 1 >> >(1, 4, dev_c);
    cudaMemcpy(&c, dev_c, sizeof(int), cudaMemcpyDeviceToHost);
    printf("1 + 4 = %d\n", c);
    cudaFree(dev_c);
}

结果是：1 + 4 = 0

但是当我尝试执行默认代码时，会在创建new project -> NVIDIA -> CUDA 6.5时自动生成。它成功构建如下：

但是当我执行它时，我得到以下内容：

addKernel launch failed: invalid device function
addWithCuda failed!press any key to continue .....

以及以下内容：

有没有人知道出了什么问题？

Answer 1

无效的设备功能错误意味着您使用错误的设备arch编译选项编译。

因此，内核无法在您的设备上运行。

据我所知，NVS 300的计算能力为1.2，但您需要通过cudaGetDeviceProperties api函数来确定它。

然后，如果它是正确的，你应该将arch编译选项设置为compute_12，sm_12在项目的属性 - > CUDA C / C ++ - ＆gt;设备 - ＆gt;代码生成。

希望这有助于解决您的问题。

CUDA内核不执行
