OpenFOAM should definitely be built against the system MPI (and, in
general, you should avoid bundled libraries wherever possible

The deprecated forms *will* disappear in a future version of Open MPI.
Please update to the new syntax.

I think Dave has probably hit the problem - that node may well not have a

I have a shared memory system, I run on the machine I build the stuff.

So, unless you turned off the default binding -- to socket? check the
mpirun man page -- it worked, but the "numa" level failed

Your Open MPI build looks good -- it seems to have found all the right libnuma

The error message you're seeing indicates that the embedded hwloc is telling

I guess the problem is not having hwloc/libnuma1 on the compute host, as

If your hwloc was built without libnuma support, you will get the
following error:

Some days ago I installed hwloc and observed "libnuma memory support:

If you're compiling Open MPI from source, you need the -devel package so that
the libnuma header files are installed (and therefore Open MPI [i.e., the hwloc
embedded in Open MPI] can include those header files and then compile support
for libnuma).
Can I also test the numa capability via a

By comparing to a similar system I found that for my 4 sockets Opteron
system it is necessary to run mpi with -bind-to numa option.
