在cuda中如何挑选gpu数组中满足特定条件的数据,并组成一个新的数组(不要把值赋给cpu计算)

Question

Passwrong << < 1, 1 >> >(cuda_dcA, cuda_dcAa, a, cuda_factAnum);
global
void Passwrong(int *a, int*b,int num,int*TN)
{

int countA = 0;
for (int ia = 0; ia < num; ia++)
{

    if (a[ia * 5] == 1 && a[ia * 5 + 1] == 1 && a[ia * 5 + 2] == 1 && a[ia * 5 + 3] == 1 && a[ia * 5 + 4] == 1)
    {
        continue;
    }
    else
    {
        for (int ja = 0; ja < 5; ja++)
        {
            b[countA * 5 + ja] = a[ia * 5 + ja];
        }
        countA++;
    }

}
TN[0] = countA;

}
这种写法会爆炸，不明原因。。。。
