16:54 <efc> Hey, we have a generator! You find all sorts of stuff rooting around the basement

16:54 <efc> 3550 watts. I'm ready for the apocalypse suckas!

17:07 <Tank_Master> can power 3 crunchers during the apocalypse!

17:07 <MTughan> As long as the fuel holds out, that is...

17:07 <Tank_Master> maybe its solar or nuclear?

17:09 <jasong> Help me out here, there's Sun java and there's ... Java

17:10 <jasong> What's the other one?

17:10 <MTughan> Microsoft Java?

17:10 <PovAddict> 'other one'? there are dozens of implementations

17:10 <Tank_Master> java script?

17:10 <jasong> Oh, god ,no

17:10 <MTughan> Microsoft did make their own Java earlier.

17:10 <jasong> Sun java is screwing up my computer, but I used one that worked

17:10 <Tank_Master> fuched up, overbloated java?

17:10 <MTughan> Oh, wouldn't be Microsoft then.

17:10 <Tank_Master> oh wait, thats sunjava

17:11 <jasong> Yeah, I have no choice if I want to play a certain game

17:11 <MTughan> I don't think they've made Java for a couple years.

17:11 *** Eythan has joined #boinc

17:11 <PovAddict> there's OpenJDK (open source version of Sun's), IBM Java, GNU Classpath + any free JVM like Kaffe...

17:11 <Tank_Master> ms cant make java anymore, for they took what sun had and made it to good

17:12 <Tank_Master> sun complained

17:12 <jasong> maybe openjdk is what I'm looking for

17:12 <jasong> thanks

17:12 <PovAddict> "too good"? they added proprietary Windows-only extensions and didn't implement the full Java spec (so some Java apps didn't work on it)

17:13 <Tank_Master> yeah, but it didnt suck when running on windows

17:13 <Tank_Master> like sun's did

17:14 <jasong> Java has the most God-awful mascot ever

17:15 <jasong> It's worse than those Olympic ones a while back

19:42 <zombie67> silly pi

19:42 <MTughan> Small WUs?

19:42 <PovAddict> silly indeed

19:43 * PovAddict watches zombie67 overload him with uploads

19:45 <zombie67> I have only two machines crunching it, I think

19:45 <PovAddict> set NNW when you think you "can't take it anymore"...

19:45 <PovAddict> ready-to-report WUs accumulate

19:45 <PovAddict> I'm trying to simulate a DD@H situation here :)

19:46 <zombie67> oh

19:46 <zombie67> in what way?

19:46 <Romulus> I guess in what way is that WAY better than what I already have, zombie67

19:46 <zombie67> you want me to build up a coupel thousand WUs and then try to return them?

19:46 <Ageless93> couple hundred should already choke the scheduler

19:46 <zombie67> I have RRI turned on

19:47 <Ageless93> which will fail if the scheduler is choked...

19:47 <Ageless93> RRI, I mean

19:47 <PovAddict> zombie67: go look at one of those machines crunching it...

19:47 <zombie67> I have about 20 ready to report

19:48 <PovAddict> I'm sure one of your machines has been uploading tons of upload files

19:48 <zombie67> could be

19:48 <PovAddict> (can't tell which from here, but it's 64-bit Windows 6.6.23)

19:48 <zombie67> yeah, they all are

19:49 <PovAddict> I set the server to do something weird: ignores returned results, so acks don't get sent, so they accumulate in the client

19:49 <zombie67> ah, you defeat my RRI

19:49 <PovAddict> at some point, I'll remove that hack, and I'll get people reporting hundreds :P

19:49 <MTughan> RRI?

19:49 <PovAddict> RRI makes your client report tasks immediately; but they fail to report now

19:50 <PovAddict> &learn RRI as Report Results Immediately

19:50 <Romulus> PovAddict: The operation succeeded.

19:50 <zombie67> return results immediately

19:50 <MTughan> Ah...

19:50 <MTughan> &whatis RRI

19:50 <Romulus> MTughan: "RRI" could be Report Results Immediately

19:50 <zombie67> rri?

19:50 <zombie67> RRI?

19:50 <PovAddict> only works "explicitly"

19:50 <MTughan> RRI is Report Results Immediately.

19:50 <MTughan> That might pick it up...

19:50 <MTughan> RRI?

19:50 <Romulus> I guess RRI is Report Results Immediately, MTughan

19:50 <MTughan> :D

19:51 <PovAddict> yes that other plugin is annoying

19:51 <PovAddict> yes that other plugin?

19:51 <Romulus> I guess yes that other plugin is annoying, PovAddict

19:51 <MTughan> lol

19:51 <Ageless93> but if the scheduler is choked, rri is defeated as well. I noticed that on DD last week. on both my machines I had to report manually at times.

19:51 <Ageless93> and even then I couldn't get through.

19:52 <zombie67> server is slow....

19:52 <PovAddict> Ageless93: well yes, it won't send acks back either :)

19:52 <PovAddict> zombie67: either I'm getting overloaded with uploads, or my sister finally got Shareaza to work

19:52 <zombie67> anyone else but me playing?

19:53 <PovAddict> lol look what I just got

19:53 <PovAddict> sáb 16 may 2009 20:47:45 ART|Silly Pi Calculation|Message from server: (reached daily quota of 400 results)

19:55 <zombie67> if I change my resource share, will the clients be able to see the change?

19:56 <PovAddict> yes

19:56 <zombie67> heh.  can't get the site to repond

19:57 <Ageless93> another one...

19:57 <zombie67> this problem with many tiny tasks reminds me of the nightmare of SciLINK

19:57 <PovAddict> remember hashclash?

19:58 <PovAddict> hashclash never got crashes for running out of memory, but it had a similar problem: the server took *too much time* to process so many reported tasks

19:58 <zombie67> I never was able to crunch for hashclash

19:58 *** quinq is now known as qzqy

19:59 <PovAddict> if I could make the file upload handler run as FastCGI, this would be a nice chance to benchmark it

19:59 <Ageless93> I must be on the right side of the connection jam. I can still get to Pov's site, be it by IP address or normal address. :)

20:00 <zombie67> the page displays after about 5 min

20:00 <PovAddict> zombie67: you sure it's not *your* connection that is slow? :)

20:00 <zombie67> yeah

20:00 <zombie67> odd, all the freehal tasks just errored out on that machine

20:01 <PovAddict> I hacked my client so it makes one less request on each upload

20:01 <PovAddict> and changed cc_config.xml to upload 8 files at a time

20:01 <PovAddict> uploads happen so much faster

20:03 <Ageless93> hmm, if I were Coca Cola I would've sent a different brand to do the music festival at the Indy 500 test and qualifying days.

20:04 <Ageless93> they've now got the Coke Zero Music festival... really bad name.

20:05 <zombie67> bbib

20:05 <PovAddict> zero music?

20:06 <PovAddict> :)

20:06 <Ageless93> they also have a Zero Stage for the DJs. ;)

20:06 <MTughan> lol

20:06 <Ageless93> so I think they clamp themselves on whatever else there's available.

20:06 <PovAddict> ok, now I did reach my daily quota, and I won't increase it further

20:07 *** infinisoft has joined #boinc

20:07 <Ageless93> less than 1100 to go

20:08 <PovAddict> still 1100?! lol

20:08 <PovAddict> I imagine when I open the floodgates for reports, I'll get four or five scheduler instances (one for each user) all trying to allocate 500 results and *boom*

20:09 <Ageless93> you're going to run the scheduler on 64MB vm?

20:09 <PovAddict> not a bad idea :)

20:09 <Ageless93> and are we even allowed to discuss that here? last time I got pointed to the door. ;)

20:10 <PovAddict> hmm ulimit

20:10 <PovAddict> I could limit how much memory each process can allocate

20:11 <Ageless93> well, you certainly know what it will do without any vm

20:11 <PovAddict> I have 2GB physical anyway :)

20:11 <zombie67> back

20:12 <zombie67> how hard to you want me to push this?

20:12 <PovAddict> heh

20:12 <PovAddict> daily quota is currently 250 per CPU

20:14 <zombie67> here we go

20:14 <zombie67> suspended everything else

20:14 <zombie67> one quad and one ocho

20:15 <PovAddict> I'm indeed getting tons of uploads from you

20:16 <zombie67> do you want me to add some more machines?

20:16 <zombie67> k

20:17 <PovAddict> whoa what a flood

20:17 <zombie67> from me?

20:17 <PovAddict> a screenful of log every 30 seconds

20:17 <PovAddict> or so

20:17 <PovAddict> http://stuff.povaddict.com.ar/nicolas/access-log.png

20:18 <zombie67> no work sent

20:18 <Romulus> <http://tinyurl.com/p4ytnm> (at stuff.povaddict.com.ar)

20:18 <zombie67> got 0 tasks

20:19 <zombie67> there we go.

20:19 <zombie67> got some this time

20:19 <zombie67> 20 tasks per request is not enough to keep my ocho fed

20:20 <PovAddict> now set to 6 second backoff between requests (was 60)

20:22 <PovAddict> now it's seriously a screenful of log every 20 seconds

20:22 <zombie67> each now has about 150 tasks

20:22 <zombie67> how high are you going to take this?

20:23 <PovAddict> I'm saving client requests in files

20:23 <PovAddict> (built-in feature of the scheduler)

20:23 <PovAddict> I just picked a random file that had 388 attempted reports :D

20:24 <PovAddict> seems to be the biggest one, actually

20:25 <PovAddict> during this test I noticed other gross inefficiencies in the server

20:25 <Ageless93> &taskmem 388

20:25 <Romulus> 388 tasks need at least 121.82131958 MB

20:25 <PovAddict> like doing four DB transactions per task sent to the client

20:26 *** Aeternus has quit IRC

20:26 <zombie67> up to 230 now on the ocho

20:28 <zombie67> test server....no exported stats

20:28 <Romulus> Title: Silly Pi Calculation (at stuff.povaddict.com.ar:8080)

20:28 <Ageless93> be quick

20:28 <PovAddict> quick before zombie67 runs it out

20:28 <Ageless93> only 289 to go

20:29 <zombie67> 250 tasks

20:29 <Ageless93> 237

20:29 <PovAddict> lol

20:29 <Ageless93> 220

20:29 <Ageless93> by the time TM is attached it's 15 ;)

20:29 * PovAddict gets network statistics

20:31 <PovAddict> I'd love a tool to get better DB stats here

20:31 <Ageless93> build it and they'll come

20:32 <Ageless93> 82

20:32 <Ageless93> and stuck at 81

20:32 <Ageless93> going once... going twice... Sold to the person in the grey Volvo

20:33 <zombie67> my quad now has 303

20:34 <zombie67> my ocho has 303

20:34 <zombie67> er, 312

20:34 <Ageless93> and we're at zero

20:34 <zombie67> "project has no jobs available"

20:35 <zombie67> now what?

20:35 <Romulus> now what is I doing before having to go for biology, zombie67

20:35 <Ageless93> now you pick your nose, of course. :)

20:35 <zombie67> is there going to be any more work issued?  If not, lemme know so I can un-suspend the other projects

20:35 <PovAddict> no plans to generate more

20:37 <PovAddict> many people are still uploading files

20:38 <Tank_Master> my host keept trying to report the same tasks

20:38 <PovAddict> Tank_Master: yep :)

20:38 <Tank_Master> and isnt requsting new work

20:38 <PovAddict> there isn't any work to send now

20:38 <Tank_Master> should still request for it

20:38 <PovAddict> once the uploads quiet down, I'll allow reports to work

20:38 <zombie67> POV is trying to duplicate DD problem

20:39 <zombie67> where hosts with many tasks cannot report

20:39 <Tank_Master> my manager never locked up

20:39 <zombie67> not your manager, it is the server that breaks

20:39 <Tank_Master> like it does with freehall

20:39 <PovAddict> zombie67: http://stuff.povaddict.com.ar/nicolas/boincmgr-expose.png

20:39 <Romulus> <http://tinyurl.com/of8qyu> (at stuff.povaddict.com.ar)

20:40 <PovAddict> boinc manager stretched across two desktops a la Mac Spaces and there's still a scrollbar :D

20:40 <Tank_Master> and why was it in high priority mode the entire time

20:40 <PovAddict> most tasks had 6-hour deadline

20:40 <PovAddict> only a few (that took like 1 minute to crunch instead of 3 seconds) had 1-hour deadlines

20:41 <Tank_Master> 13 sec was the shortest on my stom

20:41 <zombie67> neat!

20:41 <Tank_Master> atom

20:41 <zombie67> TM:  Freehal is non-CPU, silly Pi is CPU

20:42 <Tank_Master> yeah well, it still lockes up and then

20:42 <Tank_Master> I get:

20:42 <Tank_Master> 5/16/2009 5:02:46 PM|FreeHAL@home|Task newFreeHAL_45026784979-spl-de-wikipedia-wave-8--acod-5770-1-14_0 exited with a DLL initialization error.

20:42 <Tank_Master> 5/16/2009 5:02:46 PM|FreeHAL@home|If this happens repeatedly you may need to reboot your computer.

20:42 <PovAddict> zombie67: I might do a synecdoche-only run of tiny tasks at some point, if Didactylos starts working on manager improvements, would help test manager performance

20:43 <zombie67> TM, i get that sometimes.  maybe a bad bacth

20:43 <zombie67> pov, let me know if you want help testing syn(whatever)

20:44 *** sigmund_ has joined #boinc

20:48 <PovAddict> okay, I see few uploads now

20:53 <PovAddict> hmm let's set an address space of 64MB :)

20:55 *** sigmund has quit IRC

21:01 <zombie67> dinner

21:01 <PovAddict> okay, time to allow reports!

21:01 <PovAddict> I'll go down to a 32MB limit, though

21:06 <Ageless93> thunderstorms are closing in on my position. I'm closing down with the last 8 notes of the Wilhelmus. Night all.

21:06 *** Ageless93 has quit IRC

21:31 <zombie67> back

21:33 <zombie67> so...when will we try to report all these tasks?

21:37 <PovAddict> looks like there were errored tasks that got reported at some point

21:37 <PovAddict> and thus got resent ;)

21:37 <PovAddict> oh

21:37 <PovAddict> no

21:37 <PovAddict> crap

21:38 <PovAddict> there was a set of tasks that had a deadline set to 1 hour

21:38 <zombie67> so?

21:38 <Romulus> hmm... so is the company that uses the solar panels green, zombie67

21:38 <PovAddict> *those* got just resent because they didn't get reported within an hour

21:38 <PovAddict> didn't get reported for obvious reasons :)

21:38 <zombie67> ah

21:39 <zombie67> unless you accept reports, it wil keep happening until it hits the max

21:39 <PovAddict> I hadn't noticed this would happen... I guess I have to hurry and do any debugging *today*

21:39 <PovAddict> by tomorrow, the 6-hour-deadline tasks would all expire

21:40 <zombie67> you could just accpept them, and then re-issue again tomorrow

21:42 <PovAddict> now accepting reports, but with memory artificially limited; big amounts of reports will crash server

21:42 <PovAddict> = DD@H :)

21:43 <zombie67> here comes my quad

21:43 <zombie67> http:  internal error

21:43 <zombie67> 309 tasks

21:43 * PovAddict loads core dump

21:44 *** jasong has quit IRC

21:45 <PovAddict> bah, core dump seems to be truncated...

21:45 <PovAddict> limit 32MB, I need more than that

21:46 <zombie67> lemme know when to try again

21:47 <PovAddict> ugh, this may take a while

21:48 *** jasong has joined #boinc

21:51 <PovAddict> wow, it was getting truncated by like 200KB

21:51 <PovAddict> I now increased the crash dump limit to 256MB, shouldn't be a problem

21:54 <zombie67> want me to try again?

21:56 <PovAddict> wtf

21:56 <PovAddict> file_upload_handler just crashed

22:02 <MTughan> rofl... http://www.wolframalpha.com/input/?i=200+cups+of+lard

22:02 <Romulus> <http://tinyurl.com/psjfd4> (at www.wolframalpha.com)

22:02 <MTughan> Apparently, 200 cups of lard provides 63,000% of your daily fat needs.

22:08 <zombie67> yeah but that way, you just eat it once every two years.

22:28 <zombie67> dum de dum

22:30 <MTughan> &format te%s st

22:30 <Romulus> MTughan: test

22:30 <MTughan> Okay, it works...

22:30 <MTughan> &alias add wolfram "format http://www.wolframalpha.com/input/?i=%s [urlquote $*]"

22:30 <Romulus> MTughan: The operation succeeded.

22:30 <MTughan> &wolfram Neptune

22:30 <Romulus> MTughan: http://www.wolframalpha.com/input/?i=Neptune

22:30 <MTughan> Server overload ATM... But the link does work.

22:31 <PovAddict> oops I have 741MB of core dumps now >.<

22:33 <PovAddict> due to the error500s, users who have lots of tasks to report are now very backed off

22:52 <zombie67> back

22:52 <zombie67> want me to try again?

22:52 <zombie67> pov

22:56 <zombie67> same HTTP error on my side

22:57 <PovAddict> should be working now

22:57 <PovAddict> I removed the memory limit, so unless your request needs 2GB of RAM...

22:57 <zombie67> trying again

22:57 <zombie67> Ding!

22:58 <zombie67> that was 309

22:58 <zombie67> trying my other machine now

22:58 <PovAddict> yeah, without the limit it should just go

22:58 <zombie67> ah, that one had already uploaded

22:59 <zombie67> so, we know the solution?  DD can get back to work now?

22:59 <PovAddict> well, the patch I gave Jack should work to lower memory usage

23:00 <zombie67> how much memory was needed pre-patch?  and after?

23:00 <PovAddict> but the max_reports parameter maybe has to be lowered further

23:00 <PovAddict> zombie67: well, David Anderson added a setting to limit how many task reports are accepted in one request

23:01 <PovAddict> however, it's implemented stupidly: first it loads the tasks into memory, then it truncates the list according to the setting!

23:01 <PovAddict> by then, it already ran out of memory!

23:01 <PovAddict> it *might* help if the crash was when filling another DB-related list later, though

23:01 <zombie67> *snort*

23:02 <PovAddict> my patch makes the server start ignoring <result> tags in the request once the list size reaches the limit in the setting

23:02 <PovAddict> I sent it to Jack, and apparently he's still seeing crashes

23:02 <PovAddict> maybe max_reports needs lowering

23:03 <PovAddict> however, according to Jord, he "went off to see Star Trek, so don't expect him to be in here at any normal time."

23:03 <PovAddict> so we'll see tomorrow or on Monday :)

23:04 <zombie67> ah

23:08 <zombie67> seriously though, how much memory was needed pre fix?

23:08 <PovAddict> for 300 tasks?

23:08 <zombie67> sure

23:08 <PovAddict> &tasksmem 300

23:08 <Romulus> PovAddict: Are you daft?

23:08 <PovAddict> &taskmem 300

23:08 <Romulus> 300 tasks need at least 94.1917419434 MB

23:09 <zombie67> 94mb?  that's nothing

23:09 <PovAddict> note that's just how much RAM two specific arrays needed

23:09 <PovAddict> add to that all the "normal" memory usage of the program :)

23:09 <zombie67> let me ask it another way...if the server had 16gb, would that be enough?

23:10 <zombie67> 160gb?

23:10 <PovAddict> of RAM? definitely :P

23:10 <zombie67> so how small was DD memory footprint?

23:10 <PovAddict> the server has 1GB of physical RAM and no swap

23:11 <PovAddict> according to server status, they currently have 700MB used

23:11 <MTughan> No swap? That's a bad situation...

23:11 <PovAddict> oh, misread, 700 is the available :D

23:11 <zombie67> mercy....that seems foolish...even for a simple desktop

23:11 <MTughan> Even if swap is slow, it prevents out of memory errors.

23:12 <PovAddict> lots of things use their memory rarely enough that it's worth having in swap

23:12 <MTughan> That too.

23:12 <PovAddict> instead of using space in physical memory that could be used by useful things :)

23:12 <zombie67> a gig of ram costs less than $10

23:12 <zombie67> WTF?

23:13 <MTughan> I got 8GB of fast DDR2 RAM for about $170 USD.

23:13 <PovAddict> http://en.wikipedia.org/wiki/Virtual_private_server

23:13 <Romulus> <http://tinyurl.com/9tsjp> (at en.wikipedia.org)

23:13 <PovAddict> it's probably eg. a server with 32GB of RAM running 32 virtual machines one for each customer

23:13 <MTughan> Even with that, I'd still recommend about 2-4GB of swap.

23:14 <PovAddict> and the VM's RAM might end up going to the host's swap

23:15 <PovAddict> but anyway, you see it as if it was a physical machine

23:16 <zombie67> seriously, the first step is to build a reasonable box...THEN worry about the SW

23:16 <PovAddict> Jack was thinking about moving it to the H2 server

23:16 <MTughan> Is the H2 server dedicated?

23:16 <PovAddict> I think using 300 kilobytes of memory per task is ridiculous

23:16 <zombie67> heh...I think I donated to the H2 server

23:17 <MTughan> 4GB of RAM for the H2 server.

23:17 <PovAddict> a scheduling server with 128MB of RAM should be able to process thousands of reported tasks at once (as long as the DB is in a "real" server :D)

23:18 <zombie67> yeah, $100 for H2

23:18 <PovAddict> could even do DB queries while reading the request instead of reading the list of tasks into memory first

23:18 <PovAddict> O(1) memory usage

23:18 <PovAddict> but *that* would need major restructuring

23:19 <PovAddict> of the code

23:19 <MTughan> Synecdoche could be used for that.

23:20 <PovAddict> MTughan: I think it will be better if server and client forks are maintained separately; would force us to use proper specs to keep compatible

23:20 <MTughan> Yep.

23:20 <PovAddict> instead of DA's way: add code to client, add code to server

23:20 <MTughan> The problem is the currently borked XML code.

23:20 <PovAddict> nope, add code to client, post a protocol spec for the server developers to add the matching piece

23:24 <zombie67> brb

23:29 *** jasong has quit IRC

23:29 *** jasong1 has quit IRC

23:34 *** efc has joined #boinc

23:41 <zombie67> back

23:47 <efc> moo

23:52 <zombie67> oom

23:58 <zombie67> had to shut down my machines for a couple hours today.  I do that when it gets over 90F

23:58 <MTughan> Ambient or CPU?
