Giuseppe,

This is a situation that depends on the version of MPI you are using and 
is a common problem.  The output "Unrecognized argument" implies that the 
MPI launch command mpirun is interpreting psrun as an option (which it 
doesn't recognize and therefore ignores).  You might try supplying the 
full pathname to psrun, for example:

/usr/local/mpich-1.2.7/bin/mpirun -np 2 /usr/local/bin/psrun cpi-mpi

Hope this helps, 
Rick

p.s. I am redirecting your question from perfsuite-bugs to perfsuite-users
because I think this is of general interest.
