Subject: [hwloc-devel] hwloc-1.0.2 on SLES11SP2 does not honor cpuset constraints
From: Bernd Kallies (kallies_at_[hidden])

Hallo,

when I create a cpuset manually according to cpuset(7), configuring a
subset of cpus and mems of the machine for it, bind the current shell to
this cpuset, and execute lstopo, then I expect that the listed topology
shows only the resources of the cpuset. This corresponds to the default
setting of flags of the topology context (without
HWLOC_TOPOLOGY_FLAG_WHOLE_SYSTEM).

This works as expected on a machine running SLES10SP3.

Repeating the same procedure on a similar machine running SLES11SP1
fails. lstopo always lists the resources of the whole machine, and
ignores the cpuset constraint. Other things like e.g. numatools report
the expected constraint.

Please let me know how I can assist you in alayzing the problem.

Sincerely BK
