Yes, I would need such option! Please check hp-dl980g7-01.tar.bz2 attached to
my previous e-mail for an example of strange topology (uneven NUMA
distribution).
The problem is that neither --among nor --ignore works for me. Perhaps I'm
using it in a wrong way? It seems also that --among does not check if the
input is valid. Try
hwloc-distrib --single --among blabla 4
Thanks!
