[mpich-discuss] User Credential Problem on Windows

[Jayesh Krishna]

Hi,
 Condor could be running your job across machines where your
username/password is not registered.
 Did you try using delegation to run your MPI job (See section 9.4 in the
"windows developer's guide" - available at
http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=
docs)?
 
Regards,
Jayesh

Subject: [mpich-discuss] User Credential Problem on Windows



Hi,

I have MPICH2 1.0.8 installed in Windows XP.

 

I registered user credential like this

 

mpiexec -register -user 1

 

And the job is running fine, If I try like this

mpiexec -user 1 -n 6 -noprompt helloworld.exe

 

When try to submit this job using condor to run on Windows XP where I
registered user credential (user 1) using the user who runs condor job on
Windows XP.

 

Jobs are failing and I am getting the following error

 

"Credentials required to connect to the process manager on
machine.name.edu.  Please use "mpiexec -register" or "mpiexec -logon ..."
to provide user credentials.

Aborting: Unable to connect to machine.name.edu"

 

When I try using this

mpiexec -pwdfile auth.txt -n 6 -noprompt helloworld.exe

 

By having username and password in the auth.txt file and sending this file
along the job using condor, then the job runs fine.

 

Obviously we can't share this username/password file with all the users
who needs to submit MPI jobs using condor.

 

So I was wondering is there any way to run the MPI jobs without asking
user credential or is there any (Special) way  to register user credential
so that jobs running using condor will recognize this and won't fail with
the above error message.

 

Thanks,

Senthil
