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!
