[mpich-discuss] Problem using Mpich2 on Vista machines

[Larry Adams]

Jack,
 
Try the firewall first, you have to unblock the smpd service port.
Beyond that, you have to verify that smpd service is installed,  and if
it's another host, you will either have to register a pass phrase, or
your account on the execution node to be able to continue.  If your
password ever changes, you have to re-perform this step.

I've debugged as far as I can:

 

Invoking the command: mpiexec -validate -host myhost  returns:

Aborting: connection to smpd rejected

 

Invoking mpiexec -file myfile  returns:

Aborting: unable to connect to myhost

 

Some background.

 

All computers are running Vista Ultimate.  The computers are connected
by a 100mbs LAN.  A few months ago, I set up 4 machines for this use.
They all still connect without issue.

At this point I need to add some more, but am getting these errors.  All
machines have smpd version 1.0.8.  I am an administrator on all
machines, and installed Mpich2 as the administrator.  UAC was turned off
and remains off, all known firewalls are also off.  A path variable to
the bin directory  was added.

 

I ran smpd -d and all of the parameters match those of the working
computers.

 

What am I missing here?  I appreciate your valuable time.
