Thanks,
The messages are small and frequent (they flash metadata across the cluster).
The current approach works fine for small to medium clusters but I want it to
be able to go big. Maybe up to several hundred or even a thousands of nodes.
Its these larger deployments that concern me. The cu
I would appreciate someone with experience with MPI-IO look at the
simple fortran program gzipped and attached to this note. It is
imbedded in a script so that all that is necessary to run it is do:
'testio' from the command line. The program generates a small 2-D input
array, sets up an MPI-IO e

Good day,
I am new to the Open MPI package, and so am starting at the beginning. I
have little if any desire to build the binaries, so I was glad to see a
Windows binary release.
I started with I think is the minimum program:

Hi,
I compile a parallel program with OpenMPI 1.4.1 (compiled with intel

Dear all,
we succeed in building several version of openmpi from 1.2.8 to 1.4.3
with Intel composer XE 2011 (aka 12.0).
However we found a threshold in the number of cores (depending from
the application: IMB, xhpl or user applications
and form the number of required cores) above which the a
