Thanks a lot, that is most confusing part for me in MPI. I would like to<br>
clear this type of problems.<br>

So the blocking begins to send message to itself, but there is no<br>
receive posted. Thus, the MPI block it. Am I right here?<br>

Thus, I need a nonblocking receive to wait the message here. Can I use<br>
blocking receive?<br>

If you use blocking receive, you'll block in the receive; how will you reach the send?<span class="HOEnZb"><font color="#888888"><br>
