Hi, 

I have a question about the MPI listeners. Why MPI needs a
listener there all the time as long as the application
processes are running?   Do MPI listeners monitor the port
and check if there are some incomming messages? If it is
true, how the listeners communicate with the application
processes? i.e. how to pass the incomming messages to the
application processes? If not, what is the purpose of MPI listener? 
I checked the p4_sock_list.c and listener_p4.c, but I
cannot find any clue. I hope you can help me. Thank you!
