I've wondered how to implement topology changes indeed. AIX does

Maybe there's a inotify way to get such changes in Linux.
There is usually no inotify support for virtual files. I've
just tested that it doesn't work for /sys/bus/usb/devices for
instance. We'll have to ask kernel developers for it.
ok just as information osx has such a callback if possible it would
be
nice to have such functionality abstracted away...
Do you know how it is called?
I have looked for it, and was not able to find the documentation
again, I suppose that registering for power management changes and
check if for example hw.activecpu changed should do the trick, but I
cannot track down the place where I had read something about it...
(problem with macosx is that it doesn't support processor binding
anyway...)
yes it is possible just to group threads that should stay together...
