Comment intégrer CUDA .cu code C++ app

Ce post ressemble étroitement à mon précédent post: Comment séparer CUDA code en plusieurs fichiers j'ai peur j'ai fait une telle bourde de ce que j'étais en train de demander qu'il sera trop confus pour l'essayer et de le corriger.

Je suis en fondant ce code vaguement au large de la cppIntegration exemple de la CUDA SDK.

Je veux avoir une main.cpp avec mon main() fonction et l'appel à une distincte .cu fichier pour faire un peu de travail sur le GPU. Dans les séparer .cu fichier je veux qu'il soit en mesure d'appeler à mon kernel code qui se trouve dans un autre .cu fichier. J'envisage de trois fichiers: Main.cpp, KernelWrapper.cu, et Monnoyau.cu. Main.cpp pour les fins de test ne fait rien sauf l'appel d'une fonction RunTest() qui est situé dans KernelWrapper.cu. le RunTest() méthode exécute les TestDevice(int *deviceArray) noyau qui se trouve dans Monnoyau.cu

Main.cpp:

#include <iostream>

void RunTest(); //forward declaration???

int main( int argc, char** argv) 
{
    RunTest();
    std::cout << "blah\n";

    return 0;
}

KernelWrapper.cu:

#include <iostream>

__global__ void TestDevice(int *deviceArray); //forward declaration

void RunTest()
{
    int* hostArray;
    int* deviceArray;
    const int arrayLength = 16;
    const unsigned int memSize = sizeof(int) * arrayLength;

    hostArray = (int*)malloc(memSize);
    cudaMalloc((void**) &deviceArray, memSize);

    std::cout << "Before device\n";
    for(int i=0;i<arrayLength;i++)
    {
        hostArray[i] = i+1;
        std::cout << hostArray[i] << "\n";
    }
    std::cout << "\n";

    cudaMemcpy(deviceArray, hostArray, memSize, cudaMemcpyHostToDevice);
    TestDevice <<< 4, 4 >>> (deviceArray);
    cudaMemcpy(hostArray, deviceArray, memSize, cudaMemcpyDeviceToHost);

    std::cout << "After device\n";
    for(int i=0;i<arrayLength;i++)
    {
        std::cout << hostArray[i] << "\n";
    }

    cudaFree(deviceArray);
    free(hostArray);

    std::cout << "Done\n";
}

Monnoyau.cu:

#ifndef _MY_KERNEL_
#define _MY_KERNEL_

__global__ void TestDevice(int *deviceArray)
{
    int idx = blockIdx.x*blockDim.x + threadIdx.x;
    deviceArray[idx] = deviceArray[idx]*deviceArray[idx];
}

#endif
