To be future-proof (so that your code works both with current hwloc 1.x
and upcoming 2.0), the best check for non-NUMA machines is
hwloc_get_nbobjs_by_type(topology, HWLOC_OBJ_NODE) <= 1
Otherwise, yes. Infinite/full nodeset means no NUMA. To actually check
whether a nodeset is infinite, use hw
Thanks Brice for the detailed info.
So, can I say that if obj->nodeset is all 1s, it is a no NUMA mode setup?
Thanks,

Hello
If there's no NUMA node object in your hwloc topology, it means your
machine isn't NUMA (there's a single NUMA node), or your system doesn't
report NUMA information at all (missing NUMA support in the kernel, etc).
This is an old design choice that is not convenient. So we'll change
that in
Hi All,
I have recently started using hwloc and stuck with a case where there are
no NUMA nodes. I see that when i run "lscpu" command, it shows me there is
1 Numa Node and all the PUs are in this node.
But when i try reading the nodeset for my object using
hwloc_get_non_io_ancestor_obj(..), I see
