Re: [hwloc-users] Multi-Node Topologies in hwloc 2.0+
Thanks Brice for the confirmation. Best, Stephen --- Hello Stephen There's no equivalent in hwloc 2.x unfortunately, even with netloc. "custom" caused too many issues for core maintenance (mostly because of cpusets being different between machines) while use cases were very rare.

[hwloc-users] Multi-Node Topologies in hwloc 2.0+
Hi, I assume with the removal of `hwloc-assembler` and `hwloc_topology_set_custom` in 2.0+ that multi-node topology support has been relegated to netloc, but I figured I would run my use-case by you all just in case. Essentially I want to do what `hwloc-assembler` did (i.e., combine multiple single-node topologies into one big one) with the 2.0+ API. No need for any complex network connections/topologies, a simple flat `system:1 machine:X core:Y PU:Z` topology will do. With that topology, I'd like to do two things: 1) print out a human readable summary equivalent to what you get with `lstopo-no-graphics` and 2) visualize the topology with `lstopo`. Is multi-node topology like this feasible with hwloc 2.0+? If so, are there any examples or documentation on how to achieve that?
