Hello,
 
I have a process that creates other processes at different times (using MPI_Comm_spawn). After, the initial process (creator of other processes) must receive mesagens of created processes. However, there are one intercommunicator for each created process.
The question is: how to unite all the intercommunicator in a single  communicator and receive the mesagens from this single comunicator?
 
Thanks
