我正在尝试运行http://docs.thrust.googlecode.com/hg/group__modifying.html中描述的每个示例,但在编译和运行时遇到错误.

我使用以下文件:fe.cu:

#include <thrust/for_each.h>
#include <thrust/device_vector.h>
#include <stdio.h>

struct printf_functor{
    __host__ __device__
    void operator()(int x){
        printf("%d\n");
    }
};

int main(){
    thrust::device_vector<int> d_vec(3);
    d_vec[0] = 0; d_vec[1] = 1; d_vec[2] = 2;
    thrust::for_each(d_vec.begin(), d_vec.end(), printf_functor());
}

我编译nvcc -arch=sm_20 fe.cu.

当我使用./a.out运行时,我得到以下输出:

terminate called after throwing an instance of 'thrust::system::system_error'
  what():  unspecified launch failure
Aborted

以下是用于运行代码的GPU上的一些信息:
