00:11 *** abumaia has joined #boinc

00:12 <abumaia> I am running the 32bit version of Ubuntu 9.10, on a Core2 Duo system with 2.9G RAM.  Would I be well-served to switch to the 64bit version, since I run BOINC nearly 24/7?

00:45 <abumaia> well, I suppose everyone must be asleep.  I'll ask again later once somebody manages to find a cup of coffee.

06:55 <yoyo[RKN]> moin

06:56 * KathrynM waves

06:56 <yoyo[RKN]> for 1 wu I have 3 results completed in the mysql, all 3 are waiting for validation. Why they are not cached by the validator?

06:57 <yoyo[RKN]> what is the condition for the validator to validate them?

06:57 <yoyo[RKN]> example:

06:57 <Romulus> <> (at

07:40 *** KathrynM has quit IRC

08:05 <proton23> yoyo[RKN]: There is a function compare_results() in the validator, which does the magic

08:06 <proton23> but in the example it returns NULL anyway so

08:06 <proton23> I guess it's no reason there to stop

08:07 <proton23> which project are you chrunching on?

08:11 <yoyo[RKN]> I know the inside of the validator. It's my own project The question is why the validator do not un for this workunit

08:12 <yoyo[RKN]> I think the validator depends on workunit.trans_time, which is in the future for above example.

09:40 <proton23> yoyo[RKN]: How come it's in the future?

09:45 <yoyo[RKN]> that is the question

10:05 <proton23> yoyo[RKN]: where is the transition_time computed?

10:08 <proton23> yoyo[RKN]: I took a look at this

10:08 <Romulus> Title: The Logic of Backend Programs - Unofficial BOINC Wiki (at

10:08 <proton23> don't know what the Transitioner is for

10:31 <proton23> yoyo[RKN]: Where do you see the transition_time is in the future?

10:36 <yoyo[RKN]> in the workunit table

12:45 <abumaia> ah, people are awake....

12:46 <abumaia> I am running the 32bit version of Ubuntu 9.10, on a Core2 Duo system with 2.9G RAM.  Would I be well-served to switch to the 64bit version, since I run BOINC nearly 24/7?

12:52 <PovAddict> running 32-bit OS on 64-bit CPU = driving with the handbrake on

12:52 <miha> PovAddict does it matter? :D

12:52 * miha 32 bit ubuntu 9.10 on core2 too

12:55 <abumaia> or could I just run the 64bit version of BOINC?

12:55 <PovAddict> you can't run any 64-bit program on a 32-bit OS

12:58 <abumaia> do you think I'll see a definite performance boost, or not so much?

12:59 <PovAddict> it depends on the project

12:59 <PovAddict> I mean *really* depends

12:59 <PovAddict> some projects don't have 64-bit apps, so they'll just run the 32-bit app and there will be no performance difference

12:59 <PovAddict> some projects have a 64-bit app and it's 2% faster

12:59 <abumaia> seti, rosetta, docking, cpdn

12:59 <PovAddict> some projects have a 64-bit app and it's *three times* faster than 32-bit

13:01 <abumaia> so I should check each of them out, see what their 64bit stats are before committing

13:01 <PovAddict> what is sure is that going 64-bit won't make anything slower :P

13:01 <PovAddict> some programs may use a bit more RAM, but that's it

13:02 <abumaia> some people were saying to not use 64 unless you have more than 4g of ram

13:03 <Tank_Master> theres no harm that i have seen from running 64bit on systems with less than 4GB ram

13:04 <PovAddict> abumaia: not quite...

13:04 <PovAddict> if you have more than 4G of ram, you *need* 64-bit

13:04 <PovAddict> if you have less than 4G of ram, 64-bit is probably still good

13:04 <Tank_Master> hoever, if you have more than 3GB, then yes, you must have a 64bit OS to see all 4

13:05 <Tank_Master> a 32bit OS will typically see only up to 3.2-3.3GB of ram

13:05 <PovAddict> I think individual apps on 32-bit Windows can only see 2GB

13:06 <Tank_Master> yeah

13:06 <Tank_Master> but is that limited to just windows?

13:06 <Tank_Master> i thought that was a hardware limitation

13:06 <Tank_Master> but im not positive on that

13:07 <PovAddict> it's limited to Windows; in fact, you can even configure Windows to allow 3GB instead

13:07 <Tank_Master> i knew that last part

13:08 <Tank_Master> though the app itself needs to also support that configuration in order to not crash

13:08 <Tank_Master> when going above 2GB

13:16 <abumaia> well, I checked the projects, seti is down for the moment, rosetta and docking don't have 64bit native apps, cpdn probably does, but it looks like not enough do to justifiy the switch

13:21 <abumaia> ah, cpdn runs 32 on 64, like rosetta and docking.  only one I'm not sure on is seti

13:28 *** abumaia has left #boinc

13:31 <Tank_Master> ABC has a native 64bit app

13:31 <Tank_Master> as does primgrid

13:31 <Tank_Master> and aqua

13:33 <Tank_Master> i cant recall any others right off with a native 64bit app

13:33 <PovAddict> ABC is the one with most speedup afaik

13:33 <Tank_Master> primgrid has at least one app that is similer

13:34 <Tank_Master> but 64bit aqua has the highest credit per day of all of them

13:34 <Tank_Master> oh, right, collatz and milkway do as well

13:42 *** DerMeister has joined #boinc

13:46 <Tank_Master> huh, aqua has some of the 256 WUs out finally

13:46 <Tank_Master> 70h to complete 1 WU on an i7 :P

18:17 <xcamel> good enough, mate

18:24 <PovAddict> rain made a *total* mess out of buenos aires

18:28 <xcamel> another city that "makes it's own gravy"

18:29 <PovAddict> there were underground car parkings with a meter or two of water

18:31 <xcamel> yeah, that would suck.

18:32 <PovAddict> there are a few areas that still have no electricity (over 24hs now)

22:29 <efc> moo Q

22:30 <PovAddict> I just spent half an hour to print 1 page

22:30 <quail> meep meep efc

22:30 <quail> does this look little sus to peeps => BATT_HD_POWERMGMT=1 <= that what in my laptop-mode.conf file, hdd on battery should be => BATT_HD_POWERMGMT=128 ?

22:30 <efc> Write faster, Pov

22:31 <PovAddict> refused to print my black-only document for lack of magenta ink

22:31 <efc> Been there, got screwed by that

22:31 <efc> Q: Don't really know what the numbers would mean

22:32 <PovAddict> so I changed the magenta cartridge (I buy in advance because I got screwed by that situation way too many times)

22:32 <PovAddict> and it seemed to be making fun of me

22:32 <PovAddict> I told it to print, it started blinking the power led (means "busy")

22:32 <PovAddict> moved the print head around a bit

22:32 <PovAddict> and went idle again

22:32 <efc> *BURP* need more money

22:32 <quail> o.0

22:33 <quail> efc: ditto

22:33 <quail> hehe

22:33 <PovAddict> so I gave up with network print

22:33 <PovAddict> saved as PDF and printed directly from the computer with the printer

22:34 <PovAddict> using a pendrive to transfer, because file sharing over LAN is also something that always works, except when it doesn't (= when you most need it)

22:34 <efc> our lexmark does that with the magenta, f'ing piece of junk

22:34 <PovAddict> Adobe also thought it was the *perfect* moment to ask me if i wanted to upgrade Acrobat Reader

22:35 <efc> $80 to replace the black cart, then it immediately runs out of magenta, wants another $80

22:35 <PovAddict> gee, *you think I'm in the mood for that?*

22:35 <efc> Its got two other colors carts too that I assume will run out. We don't know whether to blow $240 to make it work or not.

22:36 <efc> carts are only a 1k page yield

22:36 <PovAddict> 1k? that's a lot :p

22:36 <PovAddict> my printer is like my cellphone

22:36 <PovAddict> I rarely use it

22:36 <PovAddict> when I need it, it doesn't work

22:36 <efc> our old one was $200 for 15k pages.

22:36 <efc> These carts are simply boxes of toner, too.

22:37 <PovAddict> with my prepaid phone the problem is the expiration of credits

22:37 <PovAddict> you load money into it, and if you don't use it all in a month, whatever you have left goes "poof"

22:37 <efc> I might mention that it uses magenta even on B/W prints so you WILL run out eventually.

22:38 <PovAddict> and following Murphy's law, when I need to make a call, turns out it expired

22:39 <PovAddict> do laser printers have a better lifetime when idle?

22:39 <PovAddict> I assume the problem with inkjets is the ink dries up if you don't use the printer for weeks/months

22:40 *** XioNYC has quit IRC

22:40 <PovAddict> or maybe an artificial "make user buy N cartridges per year" limitation :P

22:49 <efc> Yeah, lasers can sit idle a long time. Nothing dries out.

22:49 <PovAddict> I think my $/page goes up just because I don't print often

22:49 <PovAddict> so I get to print less pages before the printer starts complaining about ink

22:51 <efc> Just print out a test page once a week

22:52 <PovAddict> or I might just get a laser

23:12 <efc> i just tried printing on my inkjet

23:12 <efc> black has totally failed

23:12 <efc> its printed like two pages, last week
