Is anyone aware of any implementations (or even research) for accurate cpu controllers on SMP systems?
I'd like to be able to control the cpu allocated to classes (aka resource groups) with long-term (1-minute) accuracy better than .1%, and short-term (2-second) accuracy of .6% or so. I want to set the guarantees on a per-cpu basis. I need to handle the case where there are fewer tasks in a class than there are cpus--the performance hit of forced load balancing and task migration is less important than cpu share accuracy. Anyone have any pointers? Research papers? We've got the older version of ckrm working reasonably well on UP, but it pretty much fell apart on SMP.
