I may upload hwloc-gather-topology information to somewhere (about 600
kByte, which is too big to attach it to emails to your mail server)

about are these OO method names, which I
had to invent them myself. If there is some need to synchronize these
with the python binding, we may agree about them. Backwards
compatibility of the Perl binding is not a real problem, since there may
be many aliases for a function in the base XS code.

Hallo,
I'm using hwloc-1.1 on Linux 2.6.32.19 (x86_64) on a machine that has
several NUMA nodes. It seems to me that there are unwanted bits left in
the nodeset "set", when calling hwloc_get_membind_nodeset(topo,
set, ...) after a successful hwloc_set_membind() or
hwloc_set_membind_nodeset().
time. The problem is
nearly the same like having no HWLOC_API_VERSION in hwloc-0.9.

Dear all,
the Perl module Sys::Hwloc is available via CPAN, see
http://search.cpan.org/~bka/Sys-Hwloc-0.04/
Comments are welcome.

These were my ideas. Comments are welcome. Note that we have very big
machines with complicated topologies. Executing lstopo (pure C API)
takes up to a second there. It made no sense to me to slow this down
more.

of 1st Group3, 2nd task on 1st CPU of 3rd Group3 (which is the
lonely one), 3rd task on 1st CPU of 2nd Group3. Having in mind that an
MPI application that got all CPUs of this topology may start only 3
tasks and each task allocates a lot of memory far beyond than what a
single NUMA node has directly at
the
hwloc_topology_ignore_all_keep_structure approach.
