    you should be able to run mpiexec with -hosts option to specify where you want your processes/ranks be.

    You can specify different executables in the mpiexec command line:

        mpiexec [options] executable [args] [ : [options] exe [args] : ... ]

    -Fab

    If you run these commands , one instance of calc.exe program will run on node1 and  one on node2

    job submit /numnodes:1 mpiexec calc.exe

    job submit /numnodes:1 mpiexec calc.exe

    If you run these commands , two instances of calc.exe program will run on node1 and  two on node2

    job submit /numnodes:1 mpiexec -n 2 calc.exe

    job submit /numnodes:1 mpiexec -n 2 calc.exe

    However if you node has 8 cores and your application uses only 1 core , remaining 7 cores will be blocked ( allocated by HPC scheduler but unused)

    You may verify running processes on node1 and node2 remotely

    tasklist /s node1 | findstr "calc.exe"

    and you can kill process remotely

    taskkill /s node1 /F /IM calc.exe
