I could never get OpenMPI < 2.x to build on a Pi 2. I ended up using the binary
from the repos. Pi 3 is a different matter - I got that to build after a little
experimentation :)

Thanks to all who provided their opinion.
Based on the results, the Open MPI developer community will work on
v3.0.0 after the v2.1.x series.

Good afternoon sports fans!
I'm trying to run the ft code of NPB, class D, over 128 processors. I built the
code with gfortran 4.4.7 (CentOS 6 platform) and Open MPI 1.8.1. I'm using
openlava as the resource manager. The error output is the following:
[ec2-user@ip-172-31-42-106 bin]$ more runit
on an x86_64 os
to build a x86_64 binary,
is this called cross compilation ?)
my guess is raspbian gcc 4.6 is not able to compile for armv7, even
with some extra flags.
can you try
sudo apt-get install gcc-4.8 g++-4.8
and configure with CC=gcc48 CXX=g++48

Gilles,
Yes I can. I tried a simple C code ("hello world") and it compiled
and ran correctly.
Thanks!

The output from "make" is below. It died when it tried to compile
atomic-local. It says the processor doesn't support ARM mode "dmb".
Thanks!

Good afternoon,
I'm working with some AMD Interlagos nodes (16-core, 4-socket),
and I want to bind processes to cores in specific layouts. These
may not be in logical order so I need to be able to my MPI app

core ordering is the same

TIA!

Good morning,
I think I sent this out last week but I did some "experimentation"
and kind-of/sort-of got my OpenMPI application to run. But I do
have a weird problem.
I can get the application (build with OpenMPI-1.3.2 with gcc and
the app is built with Intel 10.2) to run on the IB network (not
I've got some more information (after rebuilding Open MPI and the
application a few times). I put

I get the following information back (warning - it's long).

Good morning,
I just built 1.3.2 on a ROCKS 4.something system. I built my code
(CFL3D) with the Intel 10.1 compilers. I also linked in the
OpenMPI libs and the Intel libraries to make sure I had the paths
correct. When I try running my code, I get the following,
error: executing task of job 29
I'm still looking for the new "-11" option that will allow OpenMPI compiled
code to run even faster. I'm hoping that option makes it in soon (isn't it part
of the 11.7 MPI standard?)
