Hi Shiqing,
As requested, I ran the wmic command. No problems executing notepad.exe
remotely - process with id 2416 created on remote node.
>From 10.244.166.37
C:\Users\greenbutton>wmic /node:10.243.1.134 process call create notepad.exe
Executing (Win32_Process)->Create()
Method execution successful.
Out Parameters:
instance of __PARAMETERS
{
ProcessId = 2416;
ReturnValue = 0;
};
Also no problems running the MPI command on notepad.exe

mpirun noticed that the job aborted, but has no info as to the process
that caused that situation.

(Works; blocked until notepad.exe killed on both nodes)
But:
Running my command MPIHello still does not work across nodes; I believe
there is a MPI communication problem between the processes, ie.
MPI_Send/Recv. It worked with 2 processes but not 4. How do I go about
resolving that? Is there a problem with the build settings of my executable?
