[mpich-discuss] How to terminate MPI_Comm_accept

[Roy, Hirak]

Hi Pavan,



Does not work.

Crash in nemesis.

Sock hangs in MPI_Recv/MPI_Send





Thanks,

Hirak



  MPI_Comm newComm ;

  MPI_Comm dupCom ;

  MPI_Comm_dup (MPI_COMM_SELF, &dupCom);

  MPI_Comm_connect (m_serverPort.c_str(), MPI_INFO_NULL, 0, dupCom, &newComm);

  Log ("Connect to Self");

  int val = 0 ;

  MPI_Request req ;

  MPI_Send(&val, 1, MPI_INT, 0, MPI_MSG_TAG_SHUTDOWN, newComm);

  Log ("Successful");

  MPI_Comm_disconnect(&newComm);

You can dup MPI_COMM_SELF and do the connect using that other communicator.
