I'd be against hwloc automatically spreading across multiple machines. I think
there are plenty of tools to do that already.
That being said, having better support for being able to aggregate data from
multiple hwloc instances (e.g., lstopo) on multiple machines into a single,
cohesive map,
Hello Seb,
Hwloc only looks at the local machine, there's no support for multinode
topology detection so far. We are considering adding it but we don't know yet
what users want to do with it, if it should be in the core or not, automatic or
nor. Your feedback is welcome.
