    Hello Team,

    Here I want  to run MPI program in multiple systems.

    I used "smpd -d" command to run RPC server on every system. I create a shared folder and place my executable file and try to run my program using command 

    mpiexec -hosts 2 host1 2 host2 2 shared_folder\test.exe

    It shows error like

    Aborting: Access denied by node 'host2'.
    The smpd daemon is running with user credentials which are different from the user running the job.

    How to run those command on joined-domain account.Need Help!!

    Thanks

    Seshu.

    Are you using the same user that you started "smpd -d" to launch mpiexec? MS-MPI requires that you use the same user across the machines running smpd/mpiexec. In addition, if one smpd -d daemon is launched with admin privileges, all the other daemons and mpiexec should be launched with admin privileges

    What does "using same user" mean?

    "Using the same user" is a really important information! I spent a lot of time until I found this important information.

    However, what does "same user" exactly mean? I am using the same Microsoft account on several machines, but that's not enough. I had to create the same local user across the machines running smpd/mpiexec.

    Is there any way to use the same Microsoft account instead of local user accounts with the same user name?
