CUDA--Thrust(3)--List

CUDA List 实现：

　　尽管Thrust没有提供像C++中的List容器，但是Thrust却和C++兼容。

代码：

#include "cuda_runtime.h"
#include "device_launch_parameters.h"

#include <stdio.h>

#include <thrust/host_vector.h>
#include <thrust/device_vector.h>
#include <thrust/copy.h>
#include <thrust/fill.h>
#include <thrust/sequence.h>
#include <iostream>
#include <list>
#include <vector>

int main(void) {

    int i = 0,j=0;

    // create an STL list with 4 values
    std::list<int> stl_list;
    std::list<int>::iterator it_1;
    stl_list.push_back(10);
    stl_list.push_back(20);
    stl_list.push_back(30);
    stl_list.push_back(40);

    //show the sequence stl_list
    std::cout << "show the original stl_list" << std::endl;
    for (it_1 =stl_list.begin(); it_1 !=stl_list.end(); it_1++)
        std::cout << "stl_list[" << (++i) << "]=" << *it_1 << std::endl;

    // initialize a device_vector with the list
    thrust::device_vector<int> D(stl_list.begin(), stl_list.end());
    
    //show the sequence D
    std::cout << "show the original D" << std::endl;
    for (int i = 0; i < D.size(); ++i)
        std::cout << "D[" << i << "]=" << D[i] << std::endl;

    // copy a device_vector into an STL vector
    std::vector<int> stl_vector(D.size());
    std::vector<int>::iterator it_2;
    thrust::copy(D.begin(), D.end(), stl_vector.begin());

    //show the sequence STL vector
    std::cout << "show the original STL vector" << std::endl;
    for (it_2 = stl_vector.begin(); it_2 != stl_vector.end(); it_2++)
        std::cout << "STL_vector[" << (++j) << "]=" << *it_2 << std::endl;


    
    
    return 0;
}
