[tuned] #47: Create new plugin for process scheduling/priority tuning

#47: Create new plugin for process scheduling/priority tuning --------------------------+-------------------- Reporter: jeder | Owner: Type: enhancement | Status: new Priority: major | Component: daemon Version: 2.0 | Keywords: Blocked By: | Blocking: --------------------------+-------------------- We have an init-based service now that, upon boot, applies some scheduler tuning to regexes matching threads. Below is an example: # Format is: <groupname>:<sched>:<prio>:affinity:<regex> kthreads:*:1:*:\[.*\]$ watchdog:f:99:*:\[watchdog.*\] migration:f:99:*:\[migration\/.*\] softirq:f:70:*:\[.*(softirq|sirq).*\] softirq-net-tx:f:75:*:\[(softirq|sirq)-net-tx.*\] softirq-net-rx:f:75:*:\[(softirq|sirq)-net-rx.*\] softirq-sched:f:1:*:\[(softirq|sirq)-sched\/.*\] rpciod:f:65:*:\[rpciod.*\] lockd:f:65:*:\[lockd.*\] nfsd:f:65:*:\[nfsd.*\] hardirq:f:85:*:\[(irq|IRQ)[\-_/].*\] We would like to move this functionality from the init system to a tuned profile, but it doesn't seem possible with the current tuned capabilities/plugins. In addition to one-shot tuning during profile load, there is also a use- case for monitoring new processes that are created, and applying this tuning. This could be a watchdog/scanning behavior in tuned daemon (not preferred because it creates background noise), or something more clever using perf events or even LD_PRELOAD of exec function call. -- Ticket URL: <https://fedorahosted.org/tuned/ticket/47> tuned <https://fedorahosted.org/tuned/> A daemon that performs monitoring and adaptive configuration of devices in the system.

RE: power-management Digest, Vol 28, Issue 2

Hi Jaroslav Thank you for your commit. I will create a patch by "git format-patch" if I submit in the next time. I understand that intel_pstate has only "performance" or "powersave" governor, and balanced profile and powersave profile don't work as expected(These profiles use ondemand or conservative governor.) So, I set "intel_pstate=disable" to boot parameter in my server. I think that intel_pstate isn't suitable for auto-tuning of P-State.

[patch] balanced: used conservative CPU governor
by Hase, Jin 22 Jul '14

22 Jul '14

I have an idea which improves balanced profile in tuned. This is the first time that I submit patch, so please point out if my procedure is wrong. --- balanced: used conservative CPU governor In my testing, balanced profile's efficiency is almost as same(*1) as powersave profile on my server using Xeon-E5. I think tuned should make difference between balanced profile and powersave profile. IOW, balanced profile should show better performance and worse power consumption than powersave profile. One of root causes is that detailed settings of P-State and C-State are almost same between balanced profile and powersave profile. This patch proposes that making "balanced"'s CPU governer to be conservative. This will make difference between balanced and powersave(*2).
