在 CentOS 7 中实现 MPI 发送/接收时出错

Question

我正在编译这个 MPI 程序，但它给了我 15 个错误，我不知道问题是什么。我到处寻找解决方案但一无所获。我的代码如下，我使用 CentOS 7。我可以编译并运行 OPENMPI 中的其他示例，但这个示例给了我错误。

import mpi.*;
class Hello3 {
  static public void main(String[] args) {
  MPI.Init(args) ;

 int myrank = MPI.COMM_WORLD.getRank();  
 if(myrank == 0) {
    char[] message = “Hello, there”.toCharArray();  
   MPI.COMM_WORLD.send(message, 0, message.length, MPI.CHAR, 1, 99);
 }
 else {
 char[] message = new char [20];  

 MPI.COMM_WORLD.recv(message, 0, 20, MPI.CHAR, 0, 99) ;
 System.out.println(“received:” + new String(message) + “:”);
 }
 MPI.Finalize();
}

如果尝试编译它，我会收到以下错误：
