issue on windows<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV style="TEXT-ALIGN: left"><BR>The following is our MPICH2 env settings: The
MPICH2 package is installed on machines need to run our MPI app and the user
account who installs the package has<BR>local admin permission since smpd
service needs to be started at those machines. We also create a service
account(no local admin permission) so that everyone who<BR> wants to run
MPI App can use mpiexec -register to register user credential.<BR><BR>The
service account works fine on everyone's machine except one. The problem with
that machine(it does not always happen) is that whenever it happens, it fails to
start<BR>our MPI app because of user credential issue. The error message is
that:<BR><BR> Credentials for nbkshi8a rejected connected to
machineName.<BR><BR>I check smpd service by smpd -status on this machine
whenever this happens and it seems to be running fine. Sometimes rebooting
machine will bring everything back to normal.<BR><BR>Questions:<BR><BR>a) Is
there any way to further check why this particular machine has problem from time
to time?<BR>b) We notice that, when using a service account(other than the
account which starts smpd) to start mpi app, another smpd instance will be
started on all machines on behave of this<BR>service account and will be gone
afetr MPI run ends. Is this normal?<BR>c) The way to run our MPI app is our own
app will spawn a new process to launch mpi job and sometimes it's handy if we
can redirect the error message from mpiexec to somewhere.<BR>
Is there a way to redirect error message from mpiexec to a log
file?<BR><BR>Thanks<BR><BR>Richard<BR></DIV><BR>
