By the way, lstopo shows distance information, but it does not change it
depending on -l/-p. We may want to fix this.
Thanks for the hint, I din't know it.
Actually, Linux only uses the number of hops on one specific MIPS
architecture (SGI IP27 Origin 200/2000). In other cases, it uses the
cpu-to-memory latency (usually reported by ACPI or so).
Well, this is interesting. numactl --hardware shows the number of hops, regarding to the information from that private BZ. Where does hwloc takes the distance information? Is it stored with
script? If yes, could me send me the output of hwloc-gather-topology for some NUMA box? I don't have access to any NUMA running a recent version of kernel.
This bug is private unfortunately.

OK, I will try to implement it as time permits.
