<DIV><FONT face=Arial size=2> Thanks for your
quick reply, but today I solved this issue by setting the environment
variable MPICH INTERFACE HOSTNAME with the local network interface ip
address.</FONT></DIV>

<DIV><FONT face=Arial size=2>Hello,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> I have an application running
on 5 computers under Windows Xp, they all belong to two distinct
networks. One local (A) with only these computers, and the other
one for file sharing (B) with other pcs. It doesn't</FONT><FONT
face=Arial size=2> matter if I specify the local ip (A) on the mpiexec
-host argument the data exchange always happens on network B. In the
user's guide it says to use the argument --ifhn=<ip address> on the
mpd. Does the smpd service accept this argument? Just configuring
smpd with this argument in all computers enough to be able to run on network
A?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
