09:06 <rodrigoflores> Hi

09:06 <rodrigoflores> I submitted a job using boinc_submit

09:07 <rodrigoflores> and aborted it using boinc_submit --abort jobID

09:07 <rodrigoflores> but in my client, it still runs...

09:07 *** ELGono has quit IRC

09:08 <rodrigoflores> I have to do anything else to stop a job?

09:20 <Nickuwo> rodrigoflores: was it running already when you did -abort?

09:21 <rodrigoflores> Nickuwo, yes

09:22 <Nickuwo> okay, -abort wont stop a task on a client if im not mistaken. it'll only prevent the job from being sent out again.

09:22 <Nickuwo> the client might stop the job if you force it to connect to the server again, but im not exactly sure

17:05 <ring0> hi, i'm running boinc-client version 6.4.5 on linux with everything working fine, even my nvidia gpu has been recognised as coprocessor. but somehow when clicking on a button like your results under websites in boinc-manager, it opens the website in w3m (a terminal browser) not in firefox, which is set as default browser. can i configure boinc-manager to use firefox?

17:12 *** DerMeister has quit IRC

17:16 <PovAddict> ring0: that's messed up in all operating systems

17:16 <PovAddict> not BOINC, I mean the operating systems are messed up

17:16 <PovAddict> a dozen different places saying what your preferred browser is and they're rarely in sync

17:16 <PovAddict> do you use gnome?

17:16 <ring0> yes

17:16 <MTughan_Birthday> Except on OS X, where the process is already defined. (Disclaimer: I'm an OS X dev)

17:17 <ring0> it appears to work with all apps i use except for boinc-manager

17:20 <PovAddict> it seems to use the "www-browser" symlink from the "alternatives" system

17:20 <PovAddict> in my computer, there are three browsers registered as alternatives for www-browser

17:21 <PovAddict> all three are console mode :/

17:21 <ring0> how can i figure out which alternatives are set on my machine?

17:22 <PovAddict> ah there is a different alternative called x-www-browser, for graphical browsers

17:22 * PovAddict looks in wxWidgets source code

17:23 *** mweltin has left #boinc

17:23 <ring0> ok, i see

17:24 <PovAddict> do you have "xdg-open"?

17:24 <ring0> yes, but i've never used it

17:25 <PovAddict> did you get the manager from website?

17:25 <PovAddict> or from some distro-specific package?

17:25 <ring0> from the website

17:25 <jackygrahamez_> hi

17:26 <PovAddict> RomW: what version of wxWidgets do you use for the official mgr package?

17:27 <ring0> 2.6.3

17:27 <PovAddict> 2.6? that's old... (where did you get that info btw?)

17:27 <PovAddict> ring0: run this in a terminal: gconftool-2 --get /desktop/gnome/applications/browser/exec

17:28 <ring0> i clicked Help - About Boinc Manager in the manager itself

17:28 <PovAddict> ah, didn't know wx version was there

17:29 <ring0> xdg-open worked from the terminal

17:29 <PovAddict> yeah but wxWidgets 2.6 doesn't use that anyway, I just checked... seems to be quite new

17:34 <PovAddict> ok, yeah...

17:36 <ring0> can we teach him a bit?

17:36 <PovAddict> by upgrading :P

17:36 <ring0> :)

17:36 <PovAddict> or

17:36 <PovAddict> the BROWSER environment variable

17:37 <PovAddict> try from shell: env BROWSER=/usr/bin/firefox ./run_manager

17:37 <PovAddict> see if buttons open firefox

17:39 <ring0> env: ./run_manager: No such file or directory

17:40 <PovAddict> well, run it where you installed boinc :P

17:40 <ring0> worth a shot :)

17:46 <ring0> find returns no file named run_manager on my system

17:46 <ring0> could it be boincmgr?

17:48 <ring0> alright, boincmgr worked, as did the buttons with opening the links in firefox

17:51 <ring0> could i just add "env BROWSER=/usr/bin/firefox" in front of the launcher command?

22:49 <PovAddict> his final question is

22:49 <PovAddict> "What have other projects done to avoid this kind of disaster?  Can we somehow feasibly renormalize the credit given out?  Is there any hope?"

23:00 <PovAddict> efc: CPU cache misses

23:00 <efc> I mean floating point operation counts

23:00 <efc> How many adds, multiplies, etc

23:01 <PovAddict> memory-heavy apps take longer, users *deserve* more credits for running those

23:01 <PovAddict> also, optimized apps... you do the same science with less instructions and get less credits?

23:01 <PovAddict> quoting Joel Spolsky, in the above link (who was talking about IE8 and web standards, but this seems fitting):

23:01 <PovAddict> "There is no solution. Each solution is terribly wrong. [...] It’s not a fine line. It’s a line of negative width. There is no place to walk. They are damned if they do and damned if they don’t."

23:03 <efc> It seems a decent compromise.

23:11 <zombie67> sup?

23:11 <PovAddict> know anything about AQUA, specifically, credits?

23:11 <zombie67> hah!

23:11 <zombie67> yeah

23:11 <PovAddict> or forum drama?

23:11 <zombie67> mucho drama

23:11 <PovAddict> please fill us in

23:12 <zombie67> they have a MT and GPU app

23:12 <zombie67> both seem to calculate improperly with the stock BOINC method

23:12 <zombie67> WAY too much or too small

23:13 <zombie67> anyway, so they were bullied into implementing fixed credits IMMEDIATELY

23:13 <zombie67> and messed it up

23:14 <zombie67> with the stock method, LAF was able to claim 500M credits with a single task

23:14 <zombie67> anyway, I am sure it will all get worked out eventually

23:14 <zombie67> BUT

23:14 <PovAddict> did the admin take credits off people who got too much?

23:15 <zombie67> for those couple of tasks?  sure

23:15 <PovAddict> I see someone with a RAC of thirty-five million O_O

23:15 <zombie67> but then this weekend, another fiasco

23:15 <zombie67> using fixed credits

23:15 <zombie67> anyway, this is the REAL problem

23:16 <zombie67> the technical aspect of running a project are relativly easey

23:16 <zombie67> it is the CREDIT aspect, and how it all relates to OTHER projects that keeps killing new project admins

23:16 <zombie67> there is no training for that

23:17 <zombie67> their hearts are in the right place, but they just have no experience or perspective

23:18 <zombie67> and I am sure they are now wondering if BOINC is worth the trouble

23:18 <zombie67> less pain to ask for a grant for dedicated resources

23:18 <PovAddict> I think MT and GPU isn't worth the trouble; better to stick to the normal stuff

23:19 <zombie67> that is another thing

23:19 <zombie67> the MT for win is wicked fast compared to GPU

23:19 <zombie67> which is odd

23:20 <zombie67> but the effeciency of the code and compilers for each are not similar

23:20 <PovAddict> faster than multiplied by number of cores?

23:20 <PovAddict> that is, faster than 2x when using two threads?

23:20 <zombie67> MT does it in about 8 hours

23:20 <zombie67> GPU CUDA in hundreds

23:21 <PovAddict> and "normal"?

23:21 <zombie67> and then THAT gets back to how do you award credits when you make an app so much faster?

23:21 <zombie67> what is "normal"?

23:21 <PovAddict> exactly!

23:21 <PovAddict> CPU non-MT

23:21 <PovAddict> isn't there one?

23:21 <zombie67> not any more

23:21 <zombie67> only MT and CUDA

23:22 <zombie67> CUDA and non-win MT are MT is many times faster

23:22 <zombie67> probably due to compiler

23:22 <zombie67> intel vs gcc

23:22 <zombie67> brb

23:24 <zombie67> the only way is to try to count transactions, which is also voodoo

23:25 <zombie67> which is what aqua tried to do with fixed credits, but that blew up too.

23:26 <zombie67> anyway, that is the all-too-familiar story for aqua

23:28 <zombie67> between all the message board bitching, and DA, I am sure the credit situation will drop down to a dull roar

23:29 <PovAddict> zombie67: Neil posted a scream for help in boinc_projects

23:29 <PovAddict> subject is "Catastrophe is looming; desperately need advice"

23:29 <PovAddict> 'nuff said, I guess...

23:30 <zombie67> wow, lemme read

23:30 <PovAddict> I'm about to reply with the two credit scenarios I told you about

23:31 <PovAddict> 1. optimized apps, and 2. how it gets even more hairy when other kinds of processors (GPUs) are involved

23:32 <zombie67> the first problem is with BOINC itself

23:32 <zombie67> the GPU credits are based on CPU time.  How messed up is that?

23:32 <zombie67> Also, I think there is a problem with the way MT tasks claim

23:33 <zombie67> if they MT task uses (say) 4 cores, I don't think it takes the number of cores used into consideration.

23:33 <zombie67> Still, that leaves open the cheating problem

23:42 <efc> Actual operation counts.. embrace it.

23:43 <PovAddict> how do you count them?

23:43 <efc> Some algorithms you could figure it out by the size of the problem, others you'd have to approximate

23:43 <efc> I'd say within 10% is pretty good

23:44 <efc> Of course there are other problems, like you have to agree on a weighting to the operations

23:44 <efc> an FMUL is worth 1.5 FADDs, etc

23:45 <efc> And no, it doesn't give much incentive to optimize if all you care about is credits

23:45 <efc> I guess it would actually incentivize to UNoptimize, but then if you're cheating, just go ahead and cheat

23:47 <zombie67> cheating by who?  The project or the contributors?

23:48 <efc> rogue recompilers

23:48 <PovAddict> no, it would give incentive to optimize...

23:48 <zombie67> ah!  evil admins!

23:48 <PovAddict> if you make the app do the same job with less instructions, you won't get proportionately less credits... how would BOINC / the project / the admins / anyone know how many instructions you managed to remove?

23:49 <efc> Like I said, if you can recompile, and you want to cheat, there are easier ways to cheat than that

23:50 <efc> You're saying they could optimize the app, making it take less instructions, but report the old, higher count?

23:50 <zombie67> like I said, cheaters tend to be on the client end, not the admin end

23:50 <zombie67> admins tend to want speed

23:50 <PovAddict> efc: well, if the app itself reports how many instructions it has, then you don't need to optimize at all

23:51 <PovAddict> just make it report a hundred times more :P

23:51 <efc> Yeah. Well, the s@h cobblestone count is basically a fudged instruction count. You could cheat easily, but the other clients would hopefully catch you.

23:52 <PovAddict> there's a Spanish expression that's like... "made the law, made the cheat"

23:52 <PovAddict> there's probably a proper English version of it

23:52 <zombie67> clients doing the policing??

23:53 <PovAddict> zombie67: well, it would be harder to cheat than with benchmark-based credits, but just as possible

23:53 <efc> thats what the confirmation/verification stage is doing (can't remember the name)

23:54 <zombie67> my point:  efc said that the clients would be looking out for cheating codes from the projects.  WTF??

23:54 <efc> No, the server does it

23:54 <efc> Now

23:54 <efc> Validation I think they call it?

23:54 <PovAddict> zombie67: no, the app would, like it always does, claim some number of credits

23:55 <PovAddict> validation would compare to other apps to make sure it's not an insane number

23:55 <zombie67> EFC:  You could cheat easily, but the other clients would hopefully catch you.

23:55 <PovAddict> everyone running FreeHAL is cheating, nobody caught them

23:56 <zombie67> pov, you are talking about comparing tasks from the samw WU, which does not exist for projects like AQUA

23:56 <PovAddict> ahaa! that's a problem :)

23:58 <efc> sorry, i didn't word it very well.

23:58 <zombie67> not a "problem".  It is a "typical situation"

23:58 <PovAddict> using no validation?

23:58 <PovAddict> well, no replication

23:58 <zombie67> using no comparison for validation

23:59 <efc> no replication... i think you're hosed.

23:59 <zombie67> no replication means you can't use the stoopid boinc credit method

23:59 <PovAddict> good projects waste 50% of the CPU time by using replication, and get 10x more users by giving good credits, managing the project well, etc :)
