00:31 <PovAddict> this gets more boring every year
00:32 <efc> I got the pairs some good things this time, I think.
00:34 <PovAddict> maybe next year I should stay out of this BS citing religious reasons or something (not like most other people actually care about the religious aspects of christmas, but anyway)

00:42 <PovAddict> "Christmas is a holiday which commerates the birth of Jesus Christ, wherein the baby Jesus hopped on his sleigh and delivered presents to all the children in the world."
00:50 <efc> I'll take the Gold please. You can keep the perfumes.
00:53 <PovAddict> if you compare price by volume or by weight, it wouldn't surprise me to find perfumes more expensive than gold
01:03 <efc> I think we should switch to a currency backed up by inkjet cartridges.
01:08 <PovAddict> :)
01:08 <PovAddict> seriously speaking, someone predicted the electricity kWh could become international currency in the future
01:09 <PovAddict> sounds plausible
01:10 <efc> Interesting idea.
01:10 <efc> Kind of hard to move it internationally, though.

14:50 <Migi32> hi all
14:50 <Migi32> how is this happening:
14:50 <Migi32> is it cheating or something?
14:51 <Migi32> it's the same model CPU as I have, only 700x more RAC
14:52 <PovAddict> WUProp@Home doesn't give credits for CPU usage, since it barely uses any CPU
14:53 <PovAddict> just forget that it's even possible to compare "total" credits, compare only within same project, and you'll stay sane
14:54 <Migi32> really? That's a sad thing because many people crunch for those credits and actually choose projects because they give more credits
14:56 <PovAddict> yes, and BOINC devs try to fix that by making complicated credit-granting systems that try to make all projects give the same amount of credits, but that's fundamentally impossible
14:57 <PovAddict> if a project doesn't do any CPU processing, it only does network activity, how many credits should it give? based on time, or based on bandwidth usage?
14:58 <Migi32> I would say, based on the scientific value of a processed WU
14:58 <Migi32> but that's hard to measure in credits :P
14:59 <PovAddict> that's impossible to measure objectively :P
14:59 <yoyo[RKN]> the only problem is, that some stats pages combine the credits of different projects just by summarizing them
15:00 <Migi32> however, if we at least did an attempt then silly projects like DNETC@HOME and Collatz wouldn't be #2 and #4 in the rankings
15:00 <PovAddict> Migi32: those are to blame on GPUs
15:00 * yoyo[RKN] should change the credits in yoyos projects to 1mio per hour
15:01 <PovAddict> basically there's complicated stuff to make projects give the same credits per CPU usage, and no such effort for parity per GPU usage, so the credits you get are related to how much faster their GPU app is compared to their CPU app
15:02 <PovAddict> if you think about it hard enough, you realize that the *slower* their CPU app is, the more credits they can give you for GPU work
15:02 <PovAddict> afaik no project is *intentionally* abusing that fact, but...
15:05 <Migi32> PovAddict, well ok, but there are also useful projects using a GPUGrid, which is only #9
15:05 <Migi32> projects like* GPUGrid
15:05 <Migi32> using a GPU
15:05 <PovAddict> does GPUGrid have a CPU app at all?
15:05 <Migi32> no
15:06 <Migi32> ah ok wait
15:06 <Migi32> I see what you were saying
15:09 <Migi32> does BOINC actually have control over which projects a BOINC client can connect to?
15:09 <PovAddict> as much as xchat developers have control over which IRC servers you can connect to
15:09 <PovAddict> there are many projects that the BOINC devs aren't even aware of
15:09 <PovAddict> such as ChristmasCoder's in-house financial simulations (IIRC)
15:10 <Migi32> ok, so they can't enforce any credit-giving policy
15:10 <yoyo[RKN]> no
15:10 <yoyo[RKN]> the stats pages are the problem, they just summarize credits
15:11 <PovAddict> Migi32: well, they might, but not directly
15:12 <yoyo[RKN]> they must normalize the different projects, e.g. as dc-vaults makes it
15:12 <PovAddict> Migi32: for example, I think the devs once asked a project to reduce their credits, and when they didn't do it, they threatened to ask stats sites to divide the displayed credits of that project by a factor
15:14 <Migi32> well perhaps they should normalise every project's credits by a factor that can be downloaded from boinc.berkeley.edu (so they could change that factor later)
15:15 <yoyo[RKN]> no factor
15:16 <yoyo[RKN]> project A has in total given 1000 credits and project B 10000
15:16 <yoyo[RKN]> and you have 10 in each project
15:16 <PovAddict> Migi32: please tell me what the right factor would be :P
15:16 <yoyo[RKN]> than you are ranked 10/1000 in A and 10/10000 in B
15:17 <yoyo[RKN]> and than you can add both
15:17 <yoyo[RKN]> hmm
15:17 <yoyo[RKN]> something like this
15:19 <PovAddict> that would encourage people to contribute to projects with the fewest users
15:19 <Migi32> PovAddict, that would be up for the higher-ups to decide, on a per-project basis
15:20 <yoyo[RKN]> was just an adhoc idea
15:20 <PovAddict> Migi32: but *how* would you decide?
15:21 <Migi32> no, for most projects the factor would be 1, but say a project decides to give 10x more credits than it should, you could set the factor at 0.1
15:21 <Migi32> how? let it crunch 10 WU's, then see how many credits you got for the CPU cycles spent
15:21 <yoyo[RKN]> the problem is already in one project. I have a workunit which can run on CPU@linux and on PS3 and grants 10 credits. But it needs 10h on cpu and 1h on PS3
15:21 <Migi32> well in that case there's nothing BOINC can do, it's up to the project to fix that
15:22 <Migi32> no, wait, there's nothing wrong with that. PS3's are far more powerful than CPU's
15:22 <Migi32> they shouldn't get the same credits for the same time
15:23 <PovAddict> Migi32: they should get the same credits for the same workunit
15:23 <Migi32> and in yoyo's example they do
15:23 <Romulus> Title: Foo@home's PS3 app is 3 times faster than its CPU (at pastebin.com)
15:24 <Migi32> ok, let me start again. Here's the algorithm:
15:25 <Migi32> 1. pick a computer with 1,000 double-precision MIPS based on the Whetstone benchmark (or close to it)
15:25 <Migi32> 2. crunch one day of work of a certain project
15:25 <Migi32> 3. see how many credits you got
15:26 <PovAddict> that's a simplistic view of computers
15:26 <Migi32> 4. the actual credits should be: 100 cobblestones / given credits
15:27 <Migi32> no, sorry: 4. 100*100 cobblestones / given credits
15:27 <Migi32> PovAddict, it's how credits are *defined*
15:27 <PovAddict> nope, guess what
15:28 <PovAddict> a few years ago, SETI@Home switched from benchmark-based credits to adding code to the app to estimate how many floating-point operations it did
15:28 <PovAddict> and then devs insisted other projects should give similar credits/day than SETI
15:29 <PovAddict> years later it was found that SETI had been granting twice the credits it should, because it was using flops+iops (addition) instead of (flops+iops)/2 (average)
15:30 <PovAddict> so BOINC devs quietly *changed the definition of credits* -> http://boinc.berkeley.edu/w/?title=Computation_credit&diff=2818&oldid=1126
15:31 <Migi32> heh
15:31 <Migi32> didn't know that
15:31 <Migi32> we should edit the wikipedia page then
15:31 <PovAddict> it wasn't widely announced, they wouldn't want to openly admit they were insisting other projects to adjust to something that was wrong :P
15:33 *** Caterpillar has joined #boinc
15:33 <PovAddict> either way, that definition is useless with modern computers
15:33 <Migi32> yea, I know
15:35 <Migi32> well there's probably no good solution as long as people crunch for credit
15:35 <PovAddict> I think the only way is to stop pretending cross-project credit parity is possible
15:37 <PovAddict> it works for games... I have 164,550 points in Bejeweled, and 108,424 points in Tetris, yet I don't claim I have 272,974 points total, or play the game that gives the most credits per minute played
15:37 <Migi32> maybe we should just send a mail to collatz and the like saying "dudes, you've checked 2,682,561,764,939,817,403 numbers so far, the chance you will find a counterexample is rather low and even if you do it's not a big deal. Please lower your credits/WU a little so people that go for credits actually go for something more useful."
15:38 <Migi32> PovAddict, I don't crunch for credits either, but I know there are people who do. And not just one or two guys here and there, there's a lot.
15:38 <PovAddict> people play games for points too
15:39 <PovAddict> but they know points between different games are not comparable
15:39 <Migi32> yea with "crunch for credits" I meant "crunch the project that gives the most credits"
15:42 <Migi32> btw I crunch Simap whenever I can, it doesn't give many credits and is only available a couple of days per month, but it's one of the few projects that publishes directly useful results
