Hi all,

I would like to ask you some questions:
I am trying to use the cbs algorithm [1] over separated runqueues,
providing soft guarantees on the cpu bandwidth reserved to each group,
in the form of q ns every p ns. A snapshot of my work is at:

http://feanor.sssup.it/~fabio/server_patches/

It is not working on smp and with incomplete interface (please, do not
even consider it.) Before going on, as I've seen that I'm doing some
duplicate work, and that it seems there is no agreement in the
community on the approach to take, in your opinion is what I am doing
of some interest ? Is it worth working on it (completing it and
eventually integrating with more general approaches to task grouping) ?

I cannot see any way of introducing guarantees on the current linux
scheduler, without losing its main features (O(1) complexity, POSIX
compliance, etc.) am I wrong ? Has anyone tried to do so ?

Thank you in advance,
Fabio
