[mpich-discuss] mpich2 1.0.8 on windows - domain required?

[Jayesh Krishna]

Hi,
 Can you try re-installing MPICH2 making sure that MPICH2 is installed for
"Everyone" (the default is "Just me" - the user installing MPICH2) and
re-run mpiexec ?
 Can you validate the username/password registered on mb13 using the
"-validate" option of mpiexec (mpiexec -validate)?
 
 If that does not work please provide us the debug logs for smpd/mpiexec,
 
On mb13,
 
1) Stop any instances of smpd running on the machine using the command,
smpd -stop
2) Run smpd in the debug mode & redirect the output to a log file, smpd -d
> smpd.log
3) In another command window run mpiexec in debug/verbose mode and
redirect the output to a logfile, mpiexec -verbose -n 2 hostname >
mpiexec.log
4) Provide us with the mpiexec/smpd log files.
 
Regards,
Jayesh

Yes, I've tried this.  To eliminate questions about the machine name
etc... I have

1.  go through network setup wizards again to establish that the machine
name is mb13 and the workgroup is LOGIC; disable  firewall.
(reboot)

1.5 Verify that I can share a folder on mb13, and from the other computer
can successfully map a drive to \\mb13\sharename -- this establishes that
mb13 is the recognized computer name.  And that other computers can reach
it at that name.

2.  uninstall mpich2 completely
3.  install mpich2
(reboot)

4. mpi -register, and provide username/password of an account on the
machine that is a "computer administrator" (thomas)

I still am unable to simply run mpiexec -n 2 hostname.... I get the same
"Credentials for thomas rejected connecting to mb13"

I am able to run 'smpd -status' and it tells me that smpd is running on
mb13.

Good grief... (my build from source & testing on two bsd-based macs took
about 15 minutes)

The test command suggested (mpiexec -n 2 hostname) works fine on one of
the machines.  On the other machine (both are winXP) I get the error:

Credentials for thomas rejected connecting to mb13
Aborting: Unable to connect to mb13

This is the result of just running locally, not over a network!  In answer
to the previous question, 'thomas' is not a domain user.  This is just two
winXP machines on a local network that are part of the same "workgroup"
but neither are part of any domain.  

I wonder if this has to do with my having changed the machine name on mb13
... but I have since completely uninstalled and installed mpich2.  I left
the default phrase "behappy" during this installation.  I then ran
wmpiregister and entered my username and password (which I use to login to
each machine sucessfully).

I have tried to play with wmpiconfig, but it is a little difficult to
understand how to use this.  I don't find any documentation for it.

Thanks very much for any help....

Hi,
 The machines don't have to be part of the same domain to be part of your
MPI job (This requirement is only for setups which use the SSPI
authentication mechanism to launch MPI jobs).
 Can you run a non-MPI command like hostname on the local machine ?
 
   mpiexec -n 2 hostname
 
 Is the user "thomas" a domain user ? In that case you should register the
username with the domainname (DOMAINNAME\USERNAME) when registering the
username (mpiexec -register) with mpiexec.
 Let us know if you still have problems.

Hello,

I have just subscribed to the list to ask a question about mpich2 on
windows.  (I found the archives but don't see a way to search them).

Is it a requirement that the windows computers participating in mpich2 be
part of a windows domain?  I see things in the documentation that perhaps
imply this, but not state it outright.

My computers are simply on a local network, and part of a "workgroup".
The smpd process manager can "see" the other systems to some extent, since
the result of

smpd -status mb13    // mb13 is the hostname of my other windows pc

correctly finds that smpd is running on my other host.  But executing
mpiexec and providing hostnames in a "machinefile" e.g.

mpiexec -n 4 -machinefile machines echo %COMPUTERNAME%

fails with:

Credentials for thomas rejected connecting to mb13


I have taken care that the username/pass is identical on each machine, the
user is admin, etc.  I have followed steps I've found in various documents
about uninstalling/installing smpd and providing the identical passphrase
on each, running mpiexec -register, etc...

Any ideas?  (Or is it just that I must be running on a domain, which I
cannot find concrete documentation about)

thanks very much, 
thomas blom in austin, tx
