I unfortunately don't know ifort's precedence rules for finding
modules -- I actually don't even remember if -I is the right flag to
find them. mpif90 should be adding whatever flags are necessary to
find out mpi.mod, though -- but I'm wondering if MPICH's is being
found first, since it's in /usr/local/lib. Check the ifort man page,
I guess...? An easy way to test would be to rename /usr/local/lib/
mpi.mod to be /usr/local/lib/foo.mod, and then see if your compile
works. If it does, it might be simplest to install MPICH into
somewhere other than /usr/local.
You might also want to check your distro anyway; some distros are
shipping Open MPI these days and I don't know what options you need to
select to get their version of Open MPI installed by default (or not).

I built and installed both MPICH2 and openMPI from source, so no
distribution packages or anything. MPICH2 has the modules located in
/usr/local/include, which I assume would be found (since its in my
path), were it not for specifying -I$OPENMPI_HOME/lib at compile time,
right? I can't imagine that if you tell it where to look for the
correct modules, it would search through your path first before going
to where you tell it to go. Or am I too optimistic? Thanks again for
the input!

Thanks for the reply...crap, $HOME/openmpi/lib does contains all the

That should be correct.
but still get the same
error at compile-time. Yes, I made sure to specifically build
openMPI
with ifort 10.1.012, and did run the --showme command right after
installation to make sure the wrapper compiler was using ifort as
well.
Ok, good.
Before posting to this mailing list, I did uninstall and re-install
openMPI several times to make sure I had a clean install. Still no
luck. :(
Ok. Have you checked around your machine to ensure that there is
no other
mpi.mod that the compiler is finding first? E.g., in your MPICH2
installation? Or is Open MPI installed by your distro, perchance?
You
might want to try a "rpm -qa | grep openmpi" (or whatever your
distro's
equivalent is to check already-installed packages).
