Hi Shiqing,
We went through the steps mentioned in the links to modify DCOM and COM settings. wmic /node:remote_node_ip process call create notepad.exe is able to create a notepad process remotely, but I'm getting the same error message as before using mpirun -np 2 -host host1 host2 notepad.exe. I'm running this on two Windows 7 machines both of which I have admin rights on. Any suggestions?

Hi, The Open MPI potentially uses WMI to launch remote processes, so the WMI has to be configured correctly. There are two links talking about how to set it up in README.WINDOWS file: http://msdn.microsoft.com/en-us/library/aa393266(VS.85).aspx <http://msdn.microsoft.com/en-us/library/aa393266%28VS.85%29.aspx> http://community.spiceworks.com/topic/578 For testing whether it works or not, you can use following command: wmic /node:remote_node_ip process call create notepad.exe then log onto the other Windows, check in the task manager if the notepad.exe process is created (don't forget to delete it afterwards). If that works, this command will also work: mpirun -np 2 -host host1 host2 notepad.exe Please try to run the above two test commands, if they all works you application should also work. Just let me know if you have any question or trouble with that. Shiqing On 2012-07-03 8:53 PM, vimalmat...@eaton.com wrote: Hi, I'm trying to run an MPI code using processes on a remote machine.
