SLES12 with Performance Suite has changed behaviour with respect to SLES11 on SGI-class NUMA machines.
When we use the cpuset MoM, we build a list of vnodes in PBSvnodedefs using a script called sgigenvnodelist.awk called by our init.d script.
In SLES12, though, the cpuset controller is mounted first by the cgroup infrastructure (in /sys/fs/cgroup/cpuset, and only then in /dev/cpuset. Since the first mount usually doesn't specify the "noprefix" option, what used to be the "cpus" and "mems" files in /dev/cpuset are now called "cpuset.cpus" and "cpuset.mems".
This isn't tolerated by our script.
