+The `mpiexec` code from MSMPI can be used to launch applications on multiple nodes. There are two ways to launch applications 
+on multiple nodes:
+1. Using `MSMPILaunchSVC`:
+   * Start MS-MPI Launch Service on all the compute nodes
+   * Specify your compute nodes in the `mpiexec` command line (either using `hosts` or `hostfile`)
+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)
+   * Specify your compute nodes in the `mpiexec` command line (either using `hosts` or `hostfile`)
