<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>
<DIV><FONT face=Arial size=2>Sorry about the english,</FONT></DIV>
