 1. Using MS-MPI Launch Service:
    * Start MS-MPI Launch Service on all the compute nodes
    * Specify your compute nodes in the `mpiexec` command line (either using `hosts` or `hostfile`), for example:<br>
-      `mpiexec -hosts 2 node1 1 node2 1 -wdir c:\Tests MPIHelloWorld.exe`<br>
-      The above command will run the `MPIHelloWorld.exe` program on two hosts (`node1` and `node2`) using one core from each node

 2. Using `spmd`:
    * Run `spmd -d` on all compute nodes
       * The `spmd.exe` program is availble after installation of MSMPI (in the folder pointed by the `MSMPI_BIN` variable)
