Hello, Oops, sorry, this sentence is obsolete, I am removing it from the doc right now.
We don't support the assembly of multiple machines in a single hwloc topology anymore. For the record, this feature was a very small corner case and it had important limitations (you couldn't bind things or use cpusets unless you were very careful about which host you were talking about), and it made the core hwloc code much more complex. Thanks for the report Brice Le 05/02/2018 à 23:02, Madhu, Kavitha Tiptur a écrit : > Hi > > I have a question on topology query.
