Hi Samuel,

I have installed rc3 and hwloc-distrib --single 8
will now distribute the jobs among sockets ignoring NUMA asymmetry.

./hwloc-calc --input ../../hp-dl980g7-01 --po --li --proclist $(hwloc-distrib
--input ../../hp-dl980g7-01 --single 8)
0,16,24,32,40,48,56,8

This is great! Thanks.

However, I was wondering if there is some way to get the old way, i.e to
distribute the jobs among NUMA nodes. I DO NOT use this mode but I don't want
anybody else to be harmed.

I have tried
--at numa
and
--to numa
to replicate the old behavior but without success...

Thanks
Jirka
