Oh, you are right! I didn't notice it! It seems to be indeed BIOS bug. numactl shows the same information. Luckily, [root@ibm-js22-vios-02-lp2 hwloc-1.0.1]# lstopo --ignore numanode a.xml [root@ibm-js22-vios-02-lp2 hwloc-1.0.1]# hwloc-distrib --xml a.xml --single 4 can be used to WA the issue. I'm looking forward to have --ignore switch available in hwloc-distrib once hwloc 1.1 is released. Thanks Jirka
