process-manager related commands. MPI processes, however, communicate directly
with each other during MPI communication. They don't go through MPD. You can
create virtual process topologies (graph and cartesian) using the MPI functions
for that. </FONT></SPAN></DIV>

<DIV> Dear all,<BR><BR>I have a question...<BR><BR>What are the network
topology of the mpd is it ring or tree or what ?<BR><BR>also when node wants
to send data to another nodes is it direct communication or through a ring
?<BR><BR>Also If I want to create a tree or full graphed topology
communication can this be done by the communicator?<BR><BR>Thanks
Alot.<BR><BR>Regards,<BR><BR>Hisham<BR></DIV>
