Hi Samuel,
thanks for looking into it! I'm using hwloc_distribute to distribute parallel
jobs on multi-socket systems.
Usually, it gives nice results: running
hwloc-distrib --single
on box with sockets will ditrbitute one job per socket. This is what I
want.
hwloc-distrib --single <2*N>

Hi Brice,
I had hold an internal presentation on hwloc. It was success, people has liked
it. One colleague has tried it on 8 socket box and we have found that memory
was installed in the wrong slots resulting in very strange NUMA configuration.
There was some discussion about hwloc-distrib
