Dear rhc, to make it more clear what I try to achieve, I collected some examples for several combinations of command line options. Would be great if you find time to look to these below. The most promise one is example "4".
I'd like to have 4 MPI jobs starting 1 OpenMP job each with 10 threads, running
on 2 nodes, each having 2 sockets, with 10 cores & 10 hwthreads. Only 10 cores
(no hwthreads) should be used on each socket.
4 MPI -> 1 OpenMP with 10 thread (i.e. 4x10 threads)
2 nodes, 2 sockets each, 10 cores & 10 hwthreads each
1. mpirun -np 4 --map-by ppr:2:node --mca plm_rsh_agent "qrsh" -report-bindings

I get this warning:
WARNING: a request was made to bind a process. While the system
supports binding the process itself, at least one node does NOT
support binding memory to the process location.
Node: pascal-1-05
Open MPI uses the "hwloc" library to perform process and memory
binding. This error message means that hwloc has indicated that
processor binding support is not available on this machine.
On OS X, processor and memory binding is not available at all (i.e.,
the OS does not expose this functionality).
On Linux, lack of the functionality can mean that you are on a
platform where processor and memory affinity is not supported in Linux
itself, or that hwloc was built without NUMA and/or processor affinity
support. When building hwloc (which, depending on your Open MPI
installation, may be embedded in Open MPI itself), it is important to
have the libnuma header and library files available. Different linux
distributions package these files under different names; look for
packages with the word "numa" in them. You may also need a developer
version of the package (e.g., with "dev" or "devel" in the name) to
obtain the relevant header files.
If you are getting this message on a non-OS X, non-Linux platform,
then hwloc does not support processor / memory affinity on this
platform. If the OS/platform does actually support processor / memory
affinity, then you should contact the hwloc maintainers:
https://github.com/open-mpi/hwloc.
This is a warning only; your job will continue, though performance may
be degraded.

I get a warning again:
WARNING: a request was made to bind a process. While the system
supports binding the process itself, at least one node does NOT
support binding memory to the process location.
Node: pascal-1-03
Open MPI uses the "hwloc" library to perform process and memory
binding. This error message means that hwloc has indicated that
processor binding support is not available on this machine.
On OS X, processor and memory binding is not available at all (i.e.,
the OS does not expose this functionality).
On Linux, lack of the functionality can mean that you are on a
platform where processor and memory affinity is not supported in Linux
itself, or that hwloc was built without NUMA and/or processor affinity
support. When building hwloc (which, depending on your Open MPI
installation, may be embedded in Open MPI itself), it is important to
have the libnuma header and library files available. Different linux
distributions package these files under different names; look for
packages with the word "numa" in them. You may also need a developer
version of the package (e.g., with "dev" or "devel" in the name) to
obtain the relevant header files.
If you are getting this message on a non-OS X, non-Linux platform,
then hwloc does not support processor / memory affinity on this
platform. If the OS/platform does actually support processor / memory
affinity, then you should contact the hwloc maintainers:
https://github.com/open-mpi/hwloc.
This is a warning only; your job will continue, though performance may
be degraded.

This distribution looks very well with this combination of options "--map-by
ppr:2:node --use-hwthread-cpus", with one exception: looking at "MPI Instance
0002", you'll find that "MP thread #0001" is executed on CPU 031, and "MP
thread #0005" is executed on CPU 011. 011/031 are the same physical core.
All others are real perfect! Is this error due to my fault or might their be
a small remaining binding problem in OpenMPI?
I'd appreciate any hint very much!
Kind regards,
Ado
