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

From 10.244.166.37

C:\Users\greenbutton>mpirun -np 2 -host 10.244.166.37,10.243.1.134 c:\windows\system32\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?

C:\mpi\exe>mpirun -np 2 -host 10.244.166.37,10.243.1.134 MPIHello.exe
