Jake Moilanen had a genetic algorithm autotuner for Zaphod at one time which I believe he ported over to PlugSched (as he said he was going to). However, I remove the per run queue statistics that he used to use some time ago and he hasn't complained so I've assumed that he's given up on it. I've CC'd him on this mail so he may tell you what's happening.
I could generate a patch to gather the statistic again and make them available via /proc if you would like to try a user space version of Jake's work (his was in kernel).
Peter PS The reason that I removed the stats gathering is that they add overhead which is undesirable if they're not being used so if I put them back it would probably be as a build configurable option. -- Peter Williams pwil3058@bigpond.net.au
