Problem on Windows<BR></FONT><BR></DIV>

<P class=MsoNormal>Hi,<o:p></o:p></P>
<P class=MsoNormal>I have MPICH2 1.0.8 installed in Windows XP.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I registered user credential like this<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>mpiexec –register –user 1<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>And the job is running fine, If I try like
this<o:p></o:p></P>
<P class=MsoNormal>mpiexec -user 1 -n 6 -noprompt helloworld.exe<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>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.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Jobs are failing and I am getting the following
error<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>“Credentials required to connect to the process manager on
machine.name.edu. Please use "mpiexec -register" or "mpiexec -logon ..."
to provide user credentials.<o:p></o:p></P>
<P class=MsoNormal>Aborting: Unable to connect to
machine.name.edu”<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>When I try using this<o:p></o:p></P>
<P class=MsoNormal>mpiexec -pwdfile auth.txt -n 6 -noprompt
helloworld.exe<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>By having username and password in the auth.txt file and
sending this file along the job using condor, then the job runs
fine.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Obviously we can’t share this username/password file with all
the users who needs to submit MPI jobs using condor.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>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.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>Thanks,<o:p></o:p></P>
