01:59 <dublisk> Is boinc meant for apps wriiten in languages such as C++ or Java? If I have some script that uses say matlab, can that be used with boinc?

02:03 <PovAddict> I don't think anyone has tried Java in BOINC yet

02:03 <PovAddict> at least on a public project

02:03 <PovAddict> &google matlab

02:03 <Romulus> PovAddict: Error: Error connecting to Google.com.

02:03 <efc> moo

02:04 <dublisk> hum, but any command line app can be run?

02:04 <PovAddict> I forget, is matlab free?

02:04 <dublisk> no

02:05 <PovAddict> would this be a "private" project?

02:06 <dublisk> yes

02:07 <dublisk> basically we want to setup a distributed computing system on our blade servers

02:10 <dublisk> but you can run any executable with the wrapper right?

02:13 <PovAddict> yes

02:13 <PovAddict> as long as it doesn't fork further subprocesses

02:14 <dublisk> so whats the advantage of actually compiling it against the boinc library

02:14 *** Masterx831 has quit IRC

02:15 <PovAddict> stability (having one process monitoring the other is a bit fragile), progress reporting, startup performance (no need to *copy* files into slot)

02:16 <PovAddict> http://thread.gmane.org/gmane.comp.distributed.boinc.user/1444

02:16 <Romulus> <http://tinyurl.com/yzby4sh> (at thread.gmane.org)

02:16 <dublisk> do you know about the condor project? I'm trying to understand what major differences there might be

02:17 <PovAddict> I only know two things about condor

02:17 <PovAddict> - it exists

02:17 <PovAddict> - it can run BOINC as "backfill" when it has nothing to do

02:18 <PovAddict> but I'm sure there must be some "Condor vs BOINC" paper somewhere

02:24 <dublisk> "BOINC does redundant computing to try and avoid cheating..." is this true?

02:24 <dublisk> http://www.fatbat.dk/downloads/boincThesis.pdf   page 21

02:25 <PovAddict> if you configure it that way...

02:25 <dublisk> 2.3.5

02:25 <dublisk> okay but for a private organization you can turn that off

02:25 <PovAddict> runs same task on N computers owned by different users and compares results

02:25 <dublisk> yeah thats not needed

02:26 <PovAddict> you say how much is N and what 'compare' means

16:01 <quail> 'morning all

16:01 *** rodrigoflores has joined #boinc

16:04 <rodrigoflores> I'm having a problem

16:04 <rodrigoflores> My client generates an output

16:05 <rodrigoflores> and it says that upload the output

16:05 <rodrigoflores> but I can't find the files in the server

16:05 <rodrigoflores> any hints?

16:05 <PovAddict> workflow:

16:05 <PovAddict> client processes task

16:05 <PovAddict> client uploads file to server

16:06 <PovAddict> client reports task completion

16:06 <PovAddict> on the server, the validator checks the task validity, possibly by reading output file

16:06 <PovAddict> then the assimilator does something with the validated result, like adding it to a database

16:07 <PovAddict> finally, the file_deleter deletes the output file from the server

16:07 <quail> and then the process starts again :-P

16:07 <rodrigoflores> right

16:08 <PovAddict> so you aren't supposed to "find the files in the server" at any point afterwards; you have to write an assimilator that does something with the files

16:12 <rodrigoflores> Why we have an output directory?

16:13 <PovAddict> output?

16:13 <rodrigoflores> yeap

16:14 <rodrigoflores> in the boinc project root

16:14 <PovAddict> you may want to look at the sample assimilator code

16:14 <PovAddict> do you currently have the sample assimilator enabled for your app, in config.xml?

16:15 <rodrigoflores> Let me try it

16:16 <quail> &wx ypad

16:16 <Romulus> quail: Temperature: 50°F / 10°C | Humidity: 58% | Pressure: 30.24in / 1024hPa | Conditions: Clear | Wind Direction: ENE | Wind Speed: 10mph / 17km/h | Updated: 6:30 AM CST; Unknown. High:51 F.; Scattered Clouds. Low:46 F.; Scattered Clouds. High:69 F.; Scattered Clouds. Low:51 F.; Scattered Clouds. High:77 F.; Chance of Rain. Low:55 F.;

16:17 <rodrigoflores> PovAddict, sorry, the directory is "upload" not "output"

16:17 <PovAddict> files are uploaded directly into "upload"

16:18 <PovAddict> but after the assimilator does something with them (or not!), the file deleter will delete them from there

16:18 <PovAddict> you need an assimilator that *at least* copies them somewhere else

16:18 <rodrigoflores> right

16:18 <rodrigoflores> I've put the sample assimilar

16:18 <rodrigoflores> I've put the sample assimilator

16:18 <rodrigoflores> It should put the files in the sample_results directory?

16:18 <PovAddict> yep

16:22 <rodrigoflores> It should put the output files there when the wu finishes ? Or it do the task periodically?

16:22 <PovAddict> after the WU finishes, and it's uploaded and *reported*, then it may take a few seconds

16:23 <PovAddict> technically it's a periodic task

16:23 <PovAddict> but it runs every 5 seconds, so...

16:30 <rodrigoflores> Is there any way to see in the client if my application is generating the correct output ?

16:31 <PovAddict> disable network activity :)

16:31 <PovAddict> so it's not uploaded, and you can see it in the client

16:53 *** rodrigoflores has quit IRC

17:16 *** rodrigoflores has joined #boinc

17:17 <rodrigoflores> PovAddict, I think I find my problem

17:17 <rodrigoflores> Once the legacy application is not finishing ok, the wrapper exits with errors and no output appears

17:19 <rodrigoflores> Can I run the wrapper only in the client?

17:19 <rodrigoflores> only to certify it is ok

17:19 <rodrigoflores> ?

17:19 <PovAddict> you can run the wrapper in standalone mode

17:21 <rodrigoflores> what is standalone mode?

17:21 <PovAddict> just run a science app (like the wrapper) without a client controlling it

17:22 <rodrigoflores> ok

18:09 <efc> Is it just me or is firefox getting worse at loading pages with scripts..

18:12 <PovAddict> no it's getting faster

18:13 <efc> Slashdot doesn't work very well anymore

18:13 <efc> I often get a "script taking too long" message

18:13 <efc> Could be their site I suppose

18:55 * quail does not recommend doing xforwarding on a 3G wireless connection, it so damn slow even with compression turned on, hehe

18:55 <PovAddict> lol

19:16 <quail> yeah I have to learn how to use mutt and fetchmail

19:17 <quail> xforwarding icedove is little heavy on a 3G wireless connection

19:18 <quail> but it ok when home on one my networks tho

21:40 <yomshleeshee> :-/

21:40 <yomshleeshee> not much

21:40 <yomshleeshee> I read about it

21:40 <yomshleeshee> but I wasn't sure when/where I'd use it

21:40 <yomshleeshee> certainly seemed like an interesting concept

21:42 <yomshleeshee> indeed

21:43 <yomshleeshee> and I'm getting read for comprehensive exams :-(

21:43 * yomshleeshee has no life right now

21:45 <wdsmia> enjoy it now it only gets worse once you get a career

21:47 <yomshleeshee> untill you get tenure o.O

21:48 <yomshleeshee> until*

21:48 <wdsmia> tenure is fine till you find yourself out on your ass

21:49 <wdsmia> it happens

21:49 <yomshleeshee> for some with tenure. not easily enough...

21:51 <efc> Not sure where you're from, but we don't generally have much tenure in the US

21:53 * yomshleeshee is from the US too

21:53 <yomshleeshee> yeah, I'd say it's limited to universities

21:54 <yomshleeshee> which is probably where I'll stay (unless I can't find a job o.O  )

22:00 <yomshleeshee> least we can agree on something :-D
