[mpich-discuss] Communication between child node and parent node

[abhishek pandey]

Another question,

I have two process at start, lets say A, B in COMM_WORLD  and I start some
child processes from A.
Now can any child process communicate with process B of COMM_WORLD ? If this
is possible then please let me know the way.

Thanks,
Abhishek
