[slurm-users] Wrong hwloc detected?

[Diego Zuccato]

Hello all.

Some users are reporting this error:

slurmstepd-str957-mtx-01: error: hwloc_get_obj_below_by_type() failing, 
task/affinity plugin may be required to address bug fixed in HWLOC 
version 1.11.5
slurmstepd-str957-mtx-01: error: task[0] unable to set taskset '0x0'

I checked on that node and hwloc is newer:
diego.zuccato at str957-mtx-01:~$ hwloc-info --version
hwloc-info 2.4.1

How can Slurm detect such an old HWLOC version?

BTW I'm using
  TaskPlugin=task/cgroup
in slurm.conf, and cgroup.conf contains:
  CgroupMountpoint=/sys/fs/cgroup
  ConstrainCores=yes
  TaskAffinity=yes
  ConstrainRAMSpace=yes
  ConstrainSwapSpace=yes
  MemorySwappiness=0
  MaxSwapPercent=0
  AllowedSwapSpace=0

Any ideas?

Tks.
