I have to agree with Jeff, we really need a complete program to really
debug this. Note, without really seeing what the structures look like
it is hard to determine if maybe

This shows to me that messages on the receiving sides are captured on
the basis of MPI_ANY_SOURCE, that seems like it does not see the
destination of message while capturing it from message queue of the
MPI system.

I'm going to echo what you've already heard here: it is impossible for
a process to receive a message that was sent to a different process. A
sender must specify a unique destination. No process other than the
destination process will see that message.
In what you write below, why do you th
ave more than
a broad description of the problem it is going to be nearly impossible
for us to tell you what is wrong.

I get the sender's rank in status.MPI_SOURCE, but it is different than
expected. I need to receive that message which was sent to me, not any message.

When you use MPI_ANY_SOURCE in a receive, the rank of the actual sender is
passed back to you in the status.MPI_SOURCE.

Hello people,
I am trapped in the following problem plz help me.
Suppose a process A sends a message to process B. The process B will receive
the message with MPI_Recv with MPI_ANY_SOURCE in the source argument. Let say
process B does not know that A is the sender. But I
