[mpich-discuss] Problem using Mpich2 on Vista machines

[Larry Adams]

The problem you get with simply running hostname using mpiexec in Vista,
is that if you are not a "privileged" (aka Administrators Group) user,
you won't have the required access to run hostname due to the "new and
improved" security measures.  Be prepared for fun.  This is why I used
the:
 
mpiexec -hosts 1 myhost cmd /c hostname
 
It allows you to work around this issue.  If you run without it you will
receive an Error 5 Permission Denied on the execution node.  If you
inspect the permissions of the hostname.exe file, you will understand
why.

Hi,
 
# Is SMPD installed on all the machines (Does "smpd -status" show that
SMPD is running on all the machines)?
# Can you try specifying an ipaddress instead of a hostname while
running your job (mpiexec -n 2 -host IPADDRESS_OF_HOST hostname)?
 
Regards,
Jayesh

Thanks for the quick response Larry.  Windows fire wall is off.  I can
ping the machines, and can access the machines through explorer.  The
pass phrases are all the same "behappy" and since it's all networked, my
login and passwords are the same.  Just in case, I did run the smpd
-register command to no avail.  We're attempting to work around the
problem now by cloning one of the working hard drives.

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.
