If you are using the "Job to Core Binding" feature in SGE and running
SGE on newer hardware, then please give the new hwloc enabled
loadcheck a try.


The current hardware topology discovery library (Portable Linux
Processor Affinity - PLPA) used by SGE was deprecated in 2009, and new
hardware topology may not be detected correctly by PLPA.

If you are running SGE on AMD Magny-Cours servers, please post your
loadcheck output, as it is known to be wrong when handled by PLPA.

The Open Grid Scheduler is migrating to hwloc -- we will ship hwloc
support in later releases of Grid Engine / Grid Scheduler.
