Any standard-conforming implementation of MPI supports the profiling
interface, and MPICH is no exception.  In fact, three examples of profiling
libraries are included in the MPICH distribution, and there are mechanisms
to make them particularly easy to use as well as a system to make it easy
to generate new ones.  (See the User's Guide).

I think you will find that SGI's own product MPI, included in the latest
software release, includes the profiling interface, as it has to in order to
conform to the standard specification.

One web site for lots of information on MPI, including multiple
implementations, is http://www.mcs.anl.gov/mpi .
