Use MPI_Comm_get_parent to get the intercommunicator handle for communicating with your parent. See the MPI-2.2 Standard, section 10.3.2, page 312.<br>

Hi,<br>
<br>
How can a child process can communicate with its parent ? I am spawning the processes from a node using MPI_Comm_spawn.<br>
<br>
Thanks,<br>
