They are in the package itself you get them when you install the package.
to see one of the examples install and load openmpi_ext then type:

edit <example_name>

i.e., for example

edit PI

or 

edit mc_example

Yes. OpenMPI_ext is essentially just a collection of wrappers around some of 
the 
standard MPI functions that do nothing else but define user types for Octave's 
internal data structures and then call the underlying function in openmpi.

Notice that in order for MPI_Status to work with openmpi >= 1.5 you will have 
to apply this patch:

> 4- Where I can find more reference about parallel computing in Octave?
This presentation has a section with a small overviea and a couple examples:
  http://jordi.platinum.linux.pl/octave/what-is-octave.pdf

you need to use Adobe reader to display the slides as other pdf viewers do not 
understand embedded attachments.
