Yes. Most of locality info comes from /sys/... on Linux.

Thanks for the quick response, yes lstopo -l does make the numbers
contiguous.
Another question I had was, how does hwloc populate the information that
certain cpus share a particular cache?
is it form sys/.../cache/index*/shared_cpu_list?
Thanks

Hi,
I was trying to use HWLOC on Ivybridge. I found that there is some
inconsistency in the core numbering.
In the attached image (generated from running lstopo (hwloc - 1.9.1), we
can see that cores 6,7 do not exist although, PU#6 and PU#7 does exist.
Could you have a look and let me know?
