Well, it depends...

Okay, yeah. You'd want to build OMPI with VT, but then need to find a
tool to read the data.

None of these need VT.

This doesn't need the VT in OMPI... it has its own. So, you could build
OMPI without VT and still be able to use Sun Analyzer. In fact, you
could use Sun Analyzer with a number of MPI implementations that don't
have VT in them at all.
