Mpi程序在Windows上的Vscode中无法正常运行

Question

我试图运行一些mpi程序，我从官方网站下载了.exe和.msi文件。安装后，我尝试运行示例代码，但没有成功。 一开始，错误信息说找不到mpi.h。我尝试将 mpi.h 所在的路径添加到包含路径中，错误消失了。 但仍然存在一些错误，我找不到解决的方法。 这是我的配置

演示代码

#include <iostream>
#include <mpi.h>
#include <stdint.h>
using namespace std;

int main(int argc, char* argv[]) {
  cout << "hello" << endl;
  int myid, numprocs;
  int namelen;
  char processor_name[MPI_MAX_PROCESSOR_NAME];
  MPI_Init(&argc, &argv);
  MPI_Comm_rank(MPI_COMM_WORLD, &myid);
  MPI_Comm_size(MPI_COMM_WORLD, &numprocs);
  MPI_Get_processor_name(processor_name, &namelen);
  cout << "Hello World! Process" << myid << "of" << numprocs << " on " << processor_name << endl;
  MPI_Finalize();
  return 0;
}

输出

我刚刚发现“运行代码”和“运行c/c++文件”之间的区别。这是解释。在此处输入链接描述
