[問題] CUDA 矩陣相加 error

[aada (aada)]

大家好, 想請教個問題 以下是我的程式,主要是CUDA運算矩陣加法

有些error不曉得要從拿邊修改起,
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#include<cuda.h>

__global__ void VecAdd(int* A[2][2], int* B[2][2], int* C[2][2])
{
        int i = blockIdx.x*blockDim.x+threadIdx.x; //用多區塊,多執行緒的寫法
        int j = blockIdx.y*blockDim.y+threadIdx.y; //用多區塊,多執行緒的寫法
        C[i][j] = A[i][j]+B[i][j];
}

int main()
{
        int N = 2;
        int h_A[2][2]={{1,2},{3,4}};
        int h_B[2][2]={{5,6},{7,8}};
        int *h_B2[2][2];
        int size = N*sizeof(int);

        int Grid = 1;
        int Block = 10;

        int* d_A;
        cudaMalloc((void**)&d_A, size);
        int* d_B;
        cudaMalloc((void**)&d_B, size);
        int* d_C;
        cudaMalloc((void**)&d_C, size);

        cudaMemcpy(d_A, h_A, size, cudaMemcpyHostToDevice);
        cudaMemcpy(d_B, h_B, size, cudaMemcpyHostToDevice);

        VecAdd<<<Grid, Block>>>(d_A, d_B, d_C);

        cudaMemcpy(h_B2, d_C, size, cudaMemcpyDeviceToHost);


        for(int i=0;i<N;++i)
        {
                for(int j=0;j<N;++j)
                {
                        printf("%d+%d=%d\n",h_A[i][j],h_B[i][j],h_B2[i][j]);
                }
        }

        cudaFree(d_A);
        cudaFree(d_B);
        cudaFree(d_C);

        system("PAUSE");
        return 0;

}


matrix_add.cu(11): error: expression must have integral or enum type
matrix_add.cu(43): error: argument of type "int *" is incompatible with
parameter of type "int *(*)[2]"
matrix_add.cu(43): error: argument of type "int *" is incompatible with
parameter of type "int *(*)[2]"
matrix_add.cu(43): error: argument of type "int *" is incompatible with
parameter of type "int *(*)[2]"

應該要怎麼改呢,謝謝
