First of all, thanks a lot for replying. :-)

You shouldn't need to add any -I's or -L's or -l's for Open MPI. Just
use mpic++ and mpicc (per my first note, notice that "mpicc" (lower
case) is the C compiler -- mpiCC is a synonym for the C++ compiler --
this could be your problem). Those wrappers add all the compiler /

The patch is in 1.2.6 and beyond.
It's not really a serialization issue -- it's an "early completion"
optimization, meaning that as soon as the underlying network stack
indicates that the buffer has been copied, OMPI marks the request as
complete and returns. But the data may not actually
Wow. I am indeed on IB.
So a program that calls an MPI_Bcast, then does a bunch of setup work that
should be done in parallel before re-synchronizing, in fact serializes the
setup work? I see its not quite that bad - If I run my little program on 5
nodes, I get 0 immediately, 1,2 and 4 after 5
I don't quite understand the format of this file, but at first glance,
you shouldn't need the following lines:

I guess this must depend on what BTL you're using. If I run all
processes on the same node, I get the behavior you expect. So, are you
running processes on the same node, or different nodes and, if
different, via TCP or IB?

Additionally, since you technically have a heterogeneous situation
(different OS versions on each node), you might want to:

Are you using IB, perchance?
We have an "early completion" optimization in the 1.2 series that can
cause this kind of behavior. For apps that dip into the MPI layer
frequently, it doesn't matter. But for those that do not dip into the
MPI layer frequently, it can cause delays like this.

Hi
Yuo must close the File using
MPI_File_close(MPI_File *fh)
before calling MPI_Finalize.
By the way i think you shouldn't do
strcat(argv[1], ".bz2");
This would overwrite any following arguments.
