+intelmpi is installed.
Is there something special about OpenMPI's MPI_Allreduce function call
that I should be aware of?

I appreciate your replies but my question has to do with the function
MPI_Allreduce of OpenMPI built on a Mac OSX 10.6 with ifort (intel
fortran compiler).

I did and it runs now, but the result is wrong: outside is still 1.d0,
2.d0, 3.d0, 4.d0, 5.d0
How can I make sure to compile OpenMPI so that datatypes such as
mpi_double_precision behave as they "should"?
Are there flags during the OpenMPI building process or something?
Thanks,

unlike on my Mac the code runs fine there. I am just saying that we
should stop worrying about ompi_info output and wait until Jeff Squyres
analyses my build output files that I sent to the list earlier. I might
be wrong too as I have no idea of what's going on.

On Wed,
I'm using gcc 4.8.1 and openmpi 1.7.2, both built from macports.
Inputs appreciated,

Will do, for now the best I can give is the portfile containing some
config options:
https://trac.macports.org/browser/trunk/dports/science/openmpi/Portfile
I used the gcc48 variant.

On a unrelated note, I noticed that I always get this generic message
for MPI-related compiling errors; is there a way to get more descriptive
error messages?

Hi,
I'm encountering this error during "make all":
Undefined symbols for architecture x86_64:
"___atomic_fetch_add_4", referenced from:
std::locale::locale(std::locale const&,
SpaceSeparator*) in otfprofile-create_latex.o

My apologies; I just realized that I was compiling with the LLVM
dragonegg 3.4 GCC plugin, which apparently does not support all of GCC
yet. Hopefully this will be of some help to someone in the future!

he call to MPI_Allreduce
works fine in that case. Am I doing something wrong with MPI_IN_PLACE?
I'm using OpenMPI 1.6.5 compiled with gcc 4.8.1 on Mac OS 10.8.

Now I'd be curious to know why your OpenMPI implementation handles
MPI_IN_PLACE correctly and not mine!

I checked mine and it does (I even tried to include it explicitly on the
command line but without success), what should I do next?

hence my question to this forum in the first place.
I also tried the code snippet at
https://svn.open-mpi.org/trac/ompi/ticket/1982
and that doesn't work for me either, i.e. all I get is zeros.
