The most important part of that page is the warning at the top.  If
you have a recent version of MPICH2 built with the hydra process
manager you should be able to just use that on a do nothing PE.

In addition if you have an existing MPICH2 install based on the
gforker or MPD process manager then I believe the mpiexec from a hydra
based install should be compatible with the libraries as they use the
same PMI "wire protocol".
