Sounds good, will take that part to private email.

I added printf()'s to the PLPA init(),
PLPA_NAME(sched_getaffinity)() and
PLPA_NAME(sched_setaffinity)() functions to see where
they are getting called to try and clarify what's up.

I do see init() and PLPA_NAME(sched_getaffinity)() getting
called, but never PLPA_NAME(sched_getaffinity)().

This is on my home box (quad core) not our production
clusters, but the basics should be the same..

cheers,
Chris
