Indeed, there's a big cgroup crash in 1.6. Can you verify that 1.6.1rc2 works fine?
cessenat_at_[hidden] a Ã©crit :
When updating from 1.5.1 to 1.6 I get a segfault when inside a
cgroup/cpuset in collect_proc_cpuset, file topology.c line 1074.
It appears that an HWLOC_OBJ_CORE has a son who is it's HWLOC_OBJ_GROUP's father !
$ cat /proc/self/cgroup
2: cpuset: /slurm/test
1: freezer: /
$ lssubsys -m cpuset
$ cat /cgroup/cpuset/slurm/test/cpuset.cpus
Segmentation fault (core dumped)
Program terminated with signal 11, Segmentation fault.

The machine is made of bullx super-node S6010 (CEA Tera 100).
Thanks for your help,
