Hi Brice,
thanks for the info, but it means mbind() function could does not works in
some cases?

No it just means that valgrind could properly check how hwloc uses mbind. But I
checked the hwloc code again, things look ok, and the kernel is happy with our
mbind parameters.

If I understand well,
there are parameters mismatch between mbind manual and kernel
implementation. It means that if I use mbind() directly and not by hwloc, I
could pass it wrong parameters.. or not?

No, valgrind just checks the arguments, it does not change the system
call behavior, so it should just work as usual.

Hello,
I'm having the problem that my Magny Cours system is being identified (via
hwloc-ls) as sharing an L3 cache between the NUMAnodes on a single socket. I
know that this is not actually true, and I don't know how to begin debugging
hwloc to see why it thinks that about the L3 cache. Thought
