OpenMP实现数组并行相加

int main(){int sum = 0;int a[] = {1,2,3,4,5,6,7,8};int coreNum = omp_get_num_procs();//获得处理器个数printf("处理器个数：%d\n", coreNum);int *sumArray = new int[coreNum]; //每一个处理器统计一部分总和for (int i=0; i<coreNum; ++i){sumArray[i] = 0;}#pragma omp parallel forfor (int i=0; i<8; ++i)  // 8核CPU，每个核心做一个{int k = omp_get_thread_num();// 获得每个线程的IDprintf("线程ID：%d\n", k);    sumArray[k] = sumArray[k] + a[i];}for (int i=0; i<coreNum; ++i){sum = sum + sumArray[i];}std::cout << "sum: " << sum << std::endl;system("pause");return 0;}
