I'm already using these:-)
I have also seen you recent change:
==========================
--list <type|depth>
and replaces
--nodelist with --list numanode (still supported but undocumented)
It should work for core and socket as well.
==========================
I have downloaded hwloc-1.1a1r2290.tar.bz2 but apparently the modification is
not there yet. If I get right you have implemented following, right?
===========================================
hwloc-calc --list numanode --physical proc:0
=> Should give NUMAnode to which proc:0 belongs.
hwloc-calc --list socket --physical proc:0
=> Should give Socket to which proc:0 belongs.
hwloc-calc --list core --physical proc:0
=> Should give Socket to which proc:0 belongs.
==============================================
That's would be terrific! Please let me know in which nightly build will it be
included.
I have few suggestions regarding error handling in hwloc-calc 1.0.1:
=====================================================
hwloc-calc --nodelist --physical proc:0
=> gives nothing back on systems without NUMA. I would expect some sort of
error message on stderr.
hwloc-calc --nodelist --physical proc:120
=>gives nothing back. On that system, there is NUMA but only 64 processors. I
would expect error message "proc:120 does not exist" reported on stderr.
=====================================================
Thanks a lot!
