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
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

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?

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 netloc v0.5 is obsolete even if hwloc 2.0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

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?
