Brice, We don't actually care if it is a graph or a different API. We'll anyway simply parse the graph and create our own internal structures that we can map to our internal algorithms. We simply need some model (any model) to retrieve the network topology. That's it. We'll take care of

I'm also interested in re-igniting the discussion, if others are also interested. I'm curious about the current state of netloc, and what we all want it to look like. Maybe we should move the discussion to the devel list or have a teleconf or something to kick things off? On Wed, Apr 4, 2018 at

If you really want the old netloc API now, you could try hwloc 2.x with the old netloc. But that's certainly not maintained anymore, and that only works for IB while the new netloc should have OPA and Cray support soon. The plan should rather be to tell us what you need from netloc so that we can

Brice, We want to use both hwloc and netloc in mpich. What are our options here? Move back to hwloc-1.x? That’d be a bummer because we already invested a lot of effort to migrate to hwloc-2.x. — Pavan Sent from my iPhone > On Apr 3, 2018, at 6:19 PM, Brice Goglin

It's not possible now but that would certainly be considered whenever people start using the API and linking against libnetloc. Brice Le 03/04/2018 à 21:34, Madhu, Kavitha Tiptur a écrit : > Hi > A follow up question, is it possible to build netloc along with hwloc in > embedded mode? > > >>

Hello In 2.0, netloc is still highly experimental. Hopefully, a large rework will be merged in git master next month for being released in hwloc 2.1. Most of the API from the old standalone netloc was made private when integrated in hwloc because there wasn't any actual user. The API was quite
