07:54 <ntat> Is any ifnormation on webpage about trouble in rosetta@home?

08:05 *** wdsmia_w has joined #boinc

08:51 <Tetsuo55_2> ntat : seems i can download, compute and upload new stuff, but the old upload is still stuck

08:51 <Tetsuo55_2> does anyone do climateprediction?

08:54 <Tetsuo55_2> seems to take 240h on average on my system

08:54 <Tetsuo55_2> maybe my system isnt the best choice for helping them

08:55 *** ntat has quit IRC

09:02 <ELGono> Tetsuo55_2 : climate prediction can take real long

09:02 <ELGono> don't worry about it

09:04 <Tetsuo55_2> i usually only have 72 hours a week for boinc

09:04 <Tetsuo55_2> in real clock time

09:16 <ELGono> there are statistik updates meanwhile

09:22 <ELGono> so just keep an eye on the deadline ... if you don't run too much projects in parallel, 72h/week should be enough to crunch a climate unit within time

11:46 <Marcofe> hi guys

11:47 <Marcofe> have anyone written an algorithm with boinc api?

12:05 *** Tetsuo55_2 is now known as tetsuo55

12:05 *** tetsuo55 has joined #boinc

12:25 *** lolzie has joined #boinc

12:25 <lolzie> Hey guys

12:26 <lolzie> I'm looking to contribute some processing resources (albeit not great) to a BOINC-based project, any recommendations?

12:27 <lolzie> I've looked at climateprediction.net for example, but I'd like to see something with an actual timeline/goal, so I can see I'm working towards something... these projects don't ever seem to have a x% complete or anything

12:27 <lolzie> (And I'm not talking about completion of workunits, but the overall project)

12:29 <PovAddict> most projects suck that way

12:29 <PovAddict> last month I got an email from Orbit@Home

12:30 <PovAddict> they talked too much about workunits and computation time and too little about orbits and asteroids

12:31 <lolzie> Yeah

12:31 <lolzie> It seems as though most of these projects are only interested in telling people about the bare necessities that they need to know about computation etc.

12:31 <lolzie> But I'm sure most would want to know what tangible results are being found!

12:32 <PovAddict> they're interested in keeping the BOINC nerds and credit whores informed about when they'll get work and stuff like that

12:32 <PovAddict> no wonder there's few new "outside" users

12:32 <efc> seti@home gives out some pretty good info. You have to dig for it sometimes.

12:34 <lolzie> efc: trying to find some results/reports for SETI right now, site doesn't seem to be making it easy tho!

12:34 <efc> http://home.earthlink.net/~cottongim/skymap.png

12:35 <efc> thats where my WUs fell as of a year ago or so

12:36 <lolzie> Well, I'm trying to work out how close SETI has actually came to finding life, is there anything describing that?

12:36 <lolzie> Like I say, I wish some of these projects actually gave a bit of a macroscopic overview of progress..

12:36 <efc> They are a bit more guarded with the candidate lists

12:36 <efc> I think they did put out a 10 best hits list a few years ago

12:37 <efc> which they tried to follow up, but didn't find anything

12:38 <lolzie> My only trouble with SETI in comparison to others such as folding@home is that I'm not even sure that it's based on correct premises

12:38 <lolzie> Radio signals might not even be an effective way to find life - radio *could* be something idiosyncratic to humanity

12:38 <PovAddict> I only contribute to SETI to bump my RAC just enough to let me post on their forum

12:41 <lolzie> Bah.  My only problem with them (which demotivates me greatly), is that I'll be subscribing my processor to one of these things, and never really hear much about it again

12:42 <tetsuo55> the world processing grid seems the most update stable

12:42 <tetsuo55> and rosetta@home

12:42 <tetsuo55> the former seems to force all participants to post updates twice a years

12:43 <tetsuo55> and rossetta seems to post quite regularly

12:43 <tetsuo55> and they have released many research papers

12:43 <tetsuo55> wcg

12:44 <tetsuo55> i mean this one http://www.worldcommunitygrid.org/

12:44 <Romulus> Title: World Community Grid - Home (at www.worldcommunitygrid.org)

12:44 <PovAddict> David Anderson, complaining about web ads, said "C'mon, make my day - sell me something, I dare you."

12:44 <PovAddict> I paraphrase that to "C'mon BOINC projects, convince me you deserve my CPU time, I dare you"

12:44 <tetsuo55> yes indeed

12:45 <tetsuo55> projects that dont post updates often scare me

12:45 <tetsuo55> its like they are wasting my cpu cycles instead of using them

12:45 <lolzie> Well yeah as far as I'm concerned, if I don't see any results, it's a waste

12:46 <lolzie> My intention isn't to create a load of data to be stored in some datacenter and put to no good use

12:46 <PovAddict> tetsuo55: I know of one or two projects that are genuinely wasting CPU cycles

12:46 <tetsuo55> PovAddict: which ones?

12:47 *** Aeternus has joined #boinc

12:47 <PovAddict> Goldbach's Conjecture Project

12:48 <PovAddict> it has wasted 416 years of CPU time running the BOINC sample app

12:48 <lolzie> Project CPU time*: 416 years, 201 days, 17 hours, 24 minutes.

12:48 <tetsuo55> only for testing?

12:48 <tetsuo55> insane

12:48 <lolzie> What are you saying, that the actual computation it is meant to have done only constitutes 201 days of CPU time? lol :p

12:49 <PovAddict> lolzie: there is no real app yet

12:49 <lolzie> ..ooooh.

12:49 <PovAddict> the server just keeps generating workunits for the sample do-nothing-useful app

12:49 <tetsuo55> we're not 1 inch ncloser to the proving the conjecture

12:49 <PovAddict> and ignorant users keep processing

12:49 <tetsuo55> abc feels pointless too

12:50 <tetsuo55> there are infinite possibilities

12:50 <lolzie> No sign of that at all on his site, this is exactly my point, you don't know what these projects are really doing (well, I don't)

12:50 <Marcofe> hey guy

12:50 <Marcofe> guys

12:50 <PovAddict> yeha+

12:50 <PovAddict> yeah

12:50 <Marcofe> anyone do you use boinc api?

12:50 <tetsuo55> i do not

12:50 <PovAddict> lolzie: you only notice if you go see posts in the forum written by people with a clue

12:51 <PovAddict> lolzie: or http://goldbach.pl/apps.php

12:51 <Romulus> Title: Applications (at goldbach.pl)

12:51 <tetsuo55> the only one im absolutely sure about is rosetta, because they publish research docs all the time

12:51 <lolzie> PovAddict: I can't see anything relevant on that apps.php page

12:52 <tetsuo55> and i saw a documentary where dr baker explained what they are doing

12:52 <PovAddict> lolzie: yep, unless you know what "upperCASE" is

12:52 <lolzie> PovAddict: that is EXACTLY what I just Googled :p

12:53 <lolzie> What actually is it?  Even that isn't easy to find out about.  Man, information on a lot of this BOINC-related stuff is hard to come across

12:53 *** licensed has quit IRC

12:53 <lolzie> A lot of this very much seems stuck in the 90s, the way things work

12:53 <PovAddict> lolzie: uppercase is an example application for new project admins to know how to make a BOINC app

12:54 <lolzie> Ya I gathered that much, does it actually do *anything* though?

12:54 <PovAddict> lolzie: it reads input file, converts it to uppercase, writes it to output file, then spends a few minutes doing useless maths to make the app take longer

12:54 <lolzie> ...hahaha

12:55 <lolzie> By the way, a question: don't the graphics that show computation significantly reduce actual computation speed if they're fairly in-depth?

12:56 <lolzie> Graphics seem nice, but my instinct is just to disable them completely

12:56 <PovAddict> back when there were like 4 projects, people actually used the screensaver :P

12:57 <PovAddict> and graphics often let you know what the app was actually doing right now

12:57 <PovAddict> nowadays there's few projects with any graphics

12:57 <lolzie> Oh okay

12:57 <lolzie> I'm very much a minimalist/reductionist in many ways, a bit of descriptive text will do me

12:58 <tetsuo55> PovAddict:  so which projects do you endorse most?

12:58 <tetsuo55> you dont crunch right?

12:59 <PovAddict> currently I'm running none at all because of the Evil Summer

12:59 *** Aeternus has quit IRC

13:00 <lolzie> Evil Summer?

13:01 *** Aeternus has joined #boinc

13:01 <PovAddict> lolzie: room temperature currently 28C, CPU fan at 3443RPM even with case side off and idle CPU

13:01 <lolzie> oh hehe

13:03 <lolzie> I've heard having a case side off can make it warmer (no 'refrigerator effect') - is that a load of rubbish?

13:03 <PovAddict> depends on the case

13:04 <PovAddict> sometimes the case is carefully designed to direct air flow properly, and removing the case side screws that up

13:04 <PovAddict> zombie67 said it could make other motherboard components overheat

13:04 <tetsuo55> mine are like that, but i specifically bought them for that effect

13:05 <tetsuo55> if i open the case stuff that doesnt its own cooler rises a few C

13:05 <tetsuo55> but my old crappy case

13:05 <tetsuo55> it would crash from overheating with the lid on

13:05 <tetsuo55> airflow sucked

13:06 <PovAddict> in mine, the case side has a tube covering the CPU heatsink and directing its air flow directly outside

13:06 <PovAddict> like this: http://xabbott.files.wordpress.com/2008/10/11-119-068-11.jpg

13:06 <Romulus> <http://tinyurl.com/4npsb4y> (at xabbott.files.wordpress.com)

13:06 <PovAddict> but the metal holes at the end of the tube aren't big enough, so it doesn't let enough air get out!

13:07 <tetsuo55> wow thats oldfashioned

13:07 <tetsuo55> hehe

13:07 <PovAddict> that photo is old yeah :P

13:08 *** lolzie has quit IRC

13:08 <PovAddict> just took something similar enough from Google Images :P

13:08 <tetsuo55> my case is compartmentalized

13:09 <tetsuo55> everything has its own comparement, and fans are positioned so that they blow air on misc other parts besides just the really hot ones

13:09 <tetsuo55> each comparment has an in and and out (usually fans on both sides)

13:09 <tetsuo55> so everything is very cool, even on hot summer days, although it can not be cooler than ambient

13:10 <tetsuo55> my room has natural airco so ambient is around 20c all year long

19:02 <Muligan> anybody have a boinc client installed on their *nix router?

19:03 <PovAddict> I have an off-the-shelf router, not easily hackable afaik

19:05 <Muligan> PovAddict, i'm talking about linux based servers using regular x86 equipment, aka pfsense, untangle, etc.

19:06 <PovAddict> ah

19:06 <PovAddict> what would be the problem in doing that?

19:06 <Muligan> i wouldn't see any really, except for the fact that i don't know how to administer *nix boxes all that well

19:06 <Muligan> :D

19:07 <PovAddict> it would be harder if you had an embedded but hackable router with a MIPS CPU (like a Linksys) and you wanted to run BOINC on it

19:08 <Muligan> very true

19:08 <Muligan> it's just that i have ~60 machines that i could throw a client on the crunch some further numbers on

19:13 <efc> you'd think that a lot of the emdedded machines wouldn't have much FPU but maybe they do now

19:14 <PovAddict> I wonder how much power you can get out of an iPhone CPU and GPU

19:14 <PovAddict> (although you'd have to do old-fashioned tricks to do general computation in the GPU; no CUDA or anything)
