<body class='hmmessage'><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 /><hr />Connect to the next generation of MSN Messenger <a href='http://imagine-msn.com/messenger/launch80/default.aspx?locale=en-us&source=wlmailtagline' target='_new'>Get it now! </a></body>
