Yes, Rethinking Scheduler Design http://summit.openstack.org/cfp/details/34 is not the same as the performance issue that Boris raised. I think the former would be a natural consequence of moving to an optimization-based joint decision-making framework, because such a thing necessarily takes a "good enough" attitude. The issue Boris raised is more efficient tracking of the true state of resources, and I am interested in that issue too. A holistic scheduler needs such tracking, in addition to the needs of the individual services. Having multiple consumers makes the issue more interesting :-) Regards, Mike -------------- next part -------------- An HTML attachment was scrubbed...
