16:59 <obiwan_> hi people

16:59 <obiwan_> look, somebody told me i could limit my cpu usage with the override xml in etc

17:01 <obiwan_> i edited cpu_usage_limit from 100 to 30

17:02 <obiwan_> and it's sure that my cpu stopped working at 100% all the time, but yet i don't have 30% either. I got a _really_ variable usage. I'll post the graph

17:08 <obiwan_> here

17:08 <obiwan_> http://imagebin.org/90373

17:08 <Romulus> Title: Imagebin - A place to slap up your images. (at imagebin.org)

17:09 <obiwan_> i got continuously this

17:09 <obiwan_> when i used cpulimit -p $(pidof boinc) -l 30 which limits to 30% i had a constant 30%

17:10 <obiwan_> now it's crazy, if this is a bug i'll have to keep using cpulimit instead of editing the xml config

17:16 <DerMeister> not a bug. boinc suspends the computation for some time, then resumes, then suspends, etc... on average you get your 30% cpu-usage

17:16 <ELGono> well i don't know for sure, but i bet, in xml you just set to 30% of cpu time usage.... wich can also be 30%time of 100% usage

17:16 <DerMeister> cpulimit probably does the same but with a higher frequency - which results in more overhead, by the way...

17:17 <ELGono> cpulimit is a simple program that attempts to limit the cpu usage of a process (expressed in percentage, not in cpu time)

17:17 <ELGono> first sentence from cpulimit website

17:18 *** Saenger has quit IRC

17:19 <wdsmia> re-hi

17:19 <obiwan_> ok so i think it's better cpulimit isn't it?

17:19 <obiwan_> hi wdsmia

17:19 <ELGono> lo wdsmia

17:19 <obiwan_> i mean, with cpulimit i got a constant 30% usage of my cpu, nothing more. With 30% in xml i got sometimes my cpu running at full power, which is worse for my computer

17:20 <ELGono> why is it worse?

17:21 <obiwan_> cause it's working at full power

17:22 <ELGono> in average it should be around 30% too

17:22 <obiwan_> what's better for a car engine, running at 95 mph or at 150? :P

17:22 <ELGono> depends on gear ;)

17:23 <obiwan_> that's it, my system is a macbook

17:23 <obiwan_> which gets to 90 Celsius at 100%

17:23 <ELGono> best for computer is always running boinc at 100%

17:23 <obiwan_> yeah but that's not good for my comp xD

17:23 <ELGono> cause you have less voltage drops when cpu is switching between idle and full power

17:23 <obiwan_> and no computer, no boinc xD which is worse in the end hah ^_^

17:24 <obiwan_> cpulimit limits it to constant 30%

17:24 <obiwan_> there are no drops that way

17:24 <obiwan_> i'll set that , my cpu is happy at just 70 C and my boinc runs fine

17:25 *** DerMeister has quit IRC

17:25 <ELGono> i agree to DerMeister ... cpulimit probably uses a higher frequency for limiting than boinc

17:25 <ELGono> 70C with 30%

17:25 <ELGono> that sounds hot

17:28 <ELGono> infact you have a dualcore, right?

17:28 <ELGono> why not just limiting to run on just one cpu

17:29 <ELGono> so you have just 50% usage and no extra cycles for throttling down

17:35 <obiwan_> yeah i have ELGono

17:35 <obiwan_> cause then it'd use 100% of 1 core and 0% of the other core

17:35 <obiwan_> i preffer to use 30% in each one

17:35 <obiwan_> that makes 60%

17:36 <obiwan_> heck, cpulimit doesn't work this time

17:36 <obiwan_> i got two separate processes from setiathome

17:39 *** Aeternus has joined #boinc

17:47 <PovAddict> obiwan_: there is no such thing as constant 30%

17:47 <PovAddict> either the CPU is processing or it's not

17:48 <PovAddict> so cpulimit is just switching it on and off faster than BOINC does :)

17:59 *** ELGono has quit IRC

18:17 <PovAddict> ugh

18:17 <PovAddict> David Anderson is making a complete mess with the new credit system but I have no energy to argue

18:18 <PovAddict> :/

18:18 <Tank_Master> lol

21:16 <obiwan_> sry PovAddict i had swap problems and forgot about our talk

21:17 <obiwan_> anyway ill keep using this program i like my cpu at 60 degrees ;)

21:17 <PovAddict> I have mine at 51°C

21:17 <obiwan_> thats great

21:17 <PovAddict> 100% usage

21:17 <obiwan_> wow

21:18 <obiwan_> desktop ?

21:18 <Romulus> Rumor has it desktop is running hot, but a bit more ventilation has fixed that, obiwan_

21:18 <PovAddict> yep

21:18 <obiwan_> nice hehe

21:18 <PovAddict> my old PowerBook G4 needs some cleaning

21:18 <PovAddict> I think it's overheating too easily

21:18 <obiwan_> this laptop goes like 90 for hours while compiling, i get afraid every time i complie haha

21:18 <PovAddict> fan goes full power when merely running a word processor

21:18 <obiwan_> nope, it's a hardware fault

21:19 <obiwan_> every single macbook gets this temps easily

21:19 <PovAddict> well, I think it didn't use to

21:19 <obiwan_> they say that this high temps are normal and we shouldn't get afraid but i do, and so i try not to reach them too frequently, just when really necessary

21:20 <PovAddict> just put the laptop on a block of ice

21:20 <PovAddict> :)

21:20 <obiwan_> hahahha ;P

21:20 <obiwan_> oh btw

21:21 <PovAddict> heh I bet if you have a giant ice cube (1m²) and put the BOINCing laptop on top, it'll melt all the way to the bottom pretty fast

21:21 <obiwan_> ahahah

21:21 <obiwan_> yeah i bet it will haha

21:21 <PovAddict> although with no way for the melted water to drain, more likely you'll have a floating laptop

21:22 <obiwan_> or liquid refrigeration ahahah

21:23 <obiwan_> hey man i got a new question xP

21:24 <PovAddict> just ask :)

21:24 <obiwan_> i got a pm in my boinc account off a user who i don't know, who invited me to join his team. I don't know how he knew about me, nor do i know why he wants me to join his team

21:25 <PovAddict> what project,user,team?

21:25 <obiwan_> do you know if there are massive requests of some users?

21:30 <obiwan_> it's a spanish team, i am from spain. but i accessed the spanish database and my name isn't in the last pages, so i don't know how he knew i had just joined

21:31 <obiwan_> maybe it's just a friendly message, it looks like that. but how did he know about me?

21:31 <PovAddict> did you post to the forum?

21:32 <PovAddict> PMs to ask for team membership could be considered spam

21:33 <obiwan_> nobody of my friends know that i'm usin boinc, i'm considered freak enough for them, as to top it confessing i'm using part of my cpu to find ufos hahah

21:33 <obiwan_> i didn't PovAddict

21:33 <obiwan_> the only place i talked about boinc is here, and nobody is called like that user here

21:34 <obiwan_> and i don't think i had said before i was spanish

21:34 *** zukeprime has quit IRC

21:34 <PovAddict> well if you set your country in your account, that's public info

21:35 <obiwan_> the thing is the message was in spanish, and the only thing i can think about is he knew i was spanish and asked me. but there are like thousands of spanish people in the profiles list. And i'm not in the last pages, nor in the first ones. So the only option is he pm the whole list, which sounds ridiculuous, he wouldn't last much time in boinc hehe

21:36 <PovAddict> what project? SETI?

21:36 <obiwan_> yeah

21:38 <PovAddict> can you give me a link to the profile of the user who sent it?

21:42 <obiwan_> of course

21:42 *** zukeprime has joined #boinc

21:43 <obiwan_> PovAddict: may i pm u here ?

21:43 <PovAddict> yes

21:43 <obiwan_> thx

21:43 <obiwan_> that's the user

21:45 <obiwan_> the message isn't aggresive, it just says (in spanish) "hi, wanna join my team" ?
