[mpich-discuss] Building the HP-UX MPICH library --Question

[Anthony Chan]

The user's guide and the README has info on how to launch MPICH2 compiled
executable.  The launching mechanism in MPICH2 is different from MPICH1
so reading the documents will help.  Be sure to use mpif77 to compile and link
your app.
