Segei,
can you run :
ibhosts
ibstat
ibdiagnet
Lord help me for being so naive, but do you have a subnet manager running?

Hi John !
I'm experimenting now with a head node and single compute node, all the
rest of cluster is switched off.
can you run :

Yes, I saw too that RDMA CM requires IP, but in my case OpenMPI reports
that UD CM can't be used too.
Is it also require IPoIB?
Is it pos

That's useful. Thank you.
It sounds like, as long as the component exists for OpenMPI already, it's
just a matter of compiling OpenMPI on a machine that has the headers and
libraries (with appropriate configure flags), and grabbing the individual
component from there.

Thanks for the responses, and it's great to know that you found the OMPIP
bug in 2.x for dynamic process management. I tried some of the other MPI
libraries for my project as well, but Open MPI seemed to be by far the best
in terms of being bug-free for my code!
Lisandro, I will subscribe and che
Let's try to coerce OMPI to dump all modules that are still loaded after
MPI_Init. We are still having a superset of the needed modules, but at
least everything unnecessary in your particular environment has been
trimmed as during a normal OMPI run.

To close the thread here… I got the following information:
Looking at SLURM_CPU_BIND is the right idea, but there are quite a few more
options. It misses map_cpu, rank, plus the NUMA-based options:
rank_ldom, map_ldom, and mask_ldom. See the srun man pages for documentation.

UDCM does not require IPoIB. It should be working for you. Can you build Open
MPI with --enable-debug and run with -mca btl_base_verbose 100 and create a
gist with the output.

Ah crumby!! We already solved this on master, but it cannot be backported to
the 1.10 series without considerable pain. For some reason, the support for it
has been removed from the 2.x series as well. I’ll try to resolve that issue
and get the support reinstated there (probably not until 2.1).
HI George,
Thanks for reply,
By that above script ,how can i reduce* libmpi.so* size.

Did you strip the libraries already ?
the script will show the list of frameworks and components used by MPI
helloworld.
from that, you can deduce a list of components that are not required,
exclude them via the configure command line, and rebuild a trimmed Open MPI.
