Cyril would know better but he's currently on vacation. I don't think
the required scotch release is already officially publicly available online.
I am not sure what problem you're trying to solve here. This feature
isn't really useful if you only have two nodes. It was rather designed

I tried to configure hwloc with scotch, but I still haven't success with
that case. I read Chapter 18 in doxygen and chapters about Netloc and
installation, but not found about anything about Scotch configure.
So, Scotch installed in /opt/scotch-6/ folder, and I want to install hwloc

Inside the tarball that you downloaded, there's a
doc/doxygen-doc/hwloc-a4.pdf with chapter 18 about Netloc with Scotch.
Beware that this code is still under development.

The only publicly-installed netloc API is currently specific to the
scotch partitioner for process placement. It takes a network topology
and a communication pattern between a set of process and it generates a
topology-aware placement for these processes.
This API only gets installed if you have sc
Hi again!
Can I ask you, how can I use netloc API for my C programs?
I configured hwloc only with --prefix=/opt/hwloc option. So, there are no
netloc header files in /opt/hwloc/include directory. Also, I didn't
understand how to use netloc_draw.html, because I found it only in
extracted tarball. M
Please run "hwloc-gather-topology --io foo" on the head node 'Use the
gather-topology script that comes with the hwloc nightly snapshot).
The output tarball will likely be large, so feel free to send it to me
directly.
My guess is that your very old kernel may miss some files that we need

I ran ibstat on head node it gives information in attach.

For some reason, lstopo didn't find any InfiniBand information on the
head node. I guess running lstopo won't show any "mlx4_0" or "ib0"
object. Is the InfiniBand service really running on that machine?

Please copy-paste the exact command line of your "netloc_ib_gather_raw"
and all the messages it printed. And also send the output of the hwloc

Hello
As identicated on the netloc webpages, the netloc development now occurs
inside the hwloc git tree. netloc v0.5 is obsolete even if hwloc 2.0
isn't released yet.
If you want to use a development snapshot, take hwloc nightly tarballs
from https://ci.inria.fr/hwloc/job/master-0-tarball/ or

Hi,
What version did you use?
I pushed some commits on master on ompi repository. With this version it
seems to work.
You have two machines because you tried netloc on these two?
Cyril.
