<DIV>Hi, Jayesh,</DIV>
<DIV>Thanks very much for your email. </DIV>
<DIV>I followed your suggestions and succeeded in two of my machines, which is
great !</DIV>
<DIV>However, when I am trying to get another machine involved, the same problem
appears.</DIV>
<DIV> </DIV>
<DIV>Here is my detailed description. If I run, </DIV>
<DIV>mpiexec -hosts 2 machine1 machine2 myapp.exe, it succeeds.</DIV>
<DIV> </DIV>
<DIV>However, if I run, </DIV>
<DIV>mpiexec -hosts 2 machine1 machine3 myapp.exe, it fails due to the same
error message.</DIV>
<DIV> </DIV>
<DIV>All of the 3 machines are in the same domain. </DIV>
<DIV>At the same time, I have the same passphrase for MPICH2 on 3 machines.
</DIV>
<DIV>Do you think this is something because of the IP address? </DIV>
<DIV>Or maybe I am supposed to do some configuration about the credentials on
each machine? </DIV>
<DIV>Thanks a lot. </DIV>
<DIV> </DIV>

<P><FONT size=2> Hi,<BR> The error message says that the job
launcher, mpiexec, was not able to contact the process manager, smpd, running
on machine2.<BR> Make sure that you install MPICH2 on all the
machines/hosts/nodes involved in the MPI job.<BR> Also make sure that
you disable windows firewall (or any 3rd party firewalls) on all the nodes.
You can alternately refer to the section "Runtime environment -->
firewalls" in the windows developer's guide (<A

to configure the windows firewall for MPICH2.<BR> Let us know if it
works for you.<BR><BR>Regards,<BR><SPAN class=sg>Jayesh</SPAN><SPAN
