Our Spectrum MPI and JSM teams at IBM regularly use hwloc with and without
Open MPI on a variety of ppc64le hardware including the AC922 systems. I've
personally tested the 1.11 and 2.0 series and it is working well for me on
those systems.
Let us know if you encounter any issues.

In src rpm version 4.0.1 if building with --define
'build_all_in_one_rpm 0' the grep -v _mandir docs.files is empty.
The simple workaround is to follow earlier pattern and pipe to
/bin/true, as the spec doesn't really care if the file is empty.
I'm wonderi

Hi Prentice,
We are using OpenMPI and HWLOC on POWER9 servers. The topology information
looks good from our initial use.
Let me know if you need anything specifically.

OpenMPI Users,
Are any of you using hwloc on Power9 hardware, specifically the IBM
AC922 servers? If so, have you encountered any issues? I checked the
documentation for the latest version (2.03), and found this:
Since it uses standard Operating System information, hwloc's support

Hi Tim,
it helps, up to four processes. But it has two drawbacks. 1) Using more
cores/threads than the machine provides (so the actual
over-subscription) is still not possible. 2) it still requires an
additional command line argument.
What I'd like to see is that a call of mpirun with an arbitr
Hi Steffen,
I'm not sure if this will help you (I'm by far no expert) but the mailing
group pointed by to using:
mpirun --use-hwthread-cpus
to solve something similar.
Kind regards,
Tim

Hi everyone,
on my 2 cores/4 threads development platform I want to start programs
via mpirun with over-subscription enabled by default. I have some
external packages which have tests that use more than 2 processes. They
all fail because Open MPI refuses them to run due to over-subscription.
I kno
