You need to run it via the mpiexec command. It should be on your path after installing the package. The command would be:

mpiexec -n 4 target.exe

to launch 4 images of your project's process (assuming the executable is target.exe).

Make sure you have the following in the Linker box under Compiler Flags in Project Options:

-lmpif90 -lmsmpi

I can't run the example in the file when i already download the MPI package.
it says undefined reference to 'mpi_init' etc...
