12:18 <RomW> Working on 6.8, with a projected turn around time of end of next month

12:19 <MTughan> How's ATI support coming along?

12:20 <RomW> Right now, it is on-hold...  ATI sent us a faulty card...  Or at least the SDK wouldn't install on the machine

13:02 <Nickuwo> Hey Tank

13:02 <Nickuwo> how are things

13:02 <Tank_Master> great

13:03 <Tank_Master> just ordered the parts for my i7 comp

13:03 <Nickuwo> good

13:03 <Tank_Master> though they didnt have the dvd RW avalible, its on backorder

13:04 <Nickuwo> ahh bummer

13:04 <Tank_Master> ehh, I have a spare DVD reader

13:04 <Nickuwo> what kinda vid card u gettin?

13:04 <Tank_Master> so ill used that for the time being

13:04 <Tank_Master> geforce 250

13:04 <Nickuwo> right on

13:04 <Nickuwo> nice

13:05 <Tank_Master> the 1GB version

13:06 <Tank_Master> i1 920, ASUS P6T mobo, 6GB ram, 2 300GB raptors, 120mm fan on the heatsink, 700w PS...

13:06 <Tank_Master> i7*

13:07 <Nickuwo> how much is that settin ya back?

13:07 <Tank_Master> the raptors were on sell for $200 each...

13:07 <Tank_Master> the mobo/CPU was about $525

13:07 <Tank_Master> and the rest is about $435

13:08 <Tank_Master> (reusing my case, all other parts are new)

13:08 <Nickuwo> not bad

13:08 <Tank_Master> the PS I got was 88% power efficent, so it costed a bit

13:08 <Tank_Master> about $175 right there

13:08 <Nickuwo> ya, ps aren't cheap

13:09 <Tank_Master> esp the highly efecent ones

13:09 <Tank_Master> but it should run a lot cooler and not consume as much at the wall

13:09 <Nickuwo> well when ya get it buy left 4 dead and lets kill zombies

13:13 <Nickuwo> nice

13:21 <PovAddict> my mouse wheel feels like it's gonna break

13:21 <PovAddict> I threw out a mouse because of it already

13:22 *** Rebirther has quit IRC

13:23 <Nickuwo> can you designate a WU to be GPU-only or CPU-only? or should you just use a different <application> name in the wu template?

13:24 *** Tank_Master has joined #boinc

13:27 <Nickuwo> this GPU jazz is really confusing...

13:27 <Tank_Master> :)

13:27 <Tank_Master> phun stuff

13:28 <Nickuwo> eh

13:28 <Nickuwo> :)

13:28 <MTughan> Depends on what you call fun.

13:28 <Tank_Master> p0rn

13:29 <MTughan> Or phun, as the phunny phrase goes.

13:29 <Nickuwo> hmm, nothing about GPU-only WUs in the wiki

13:31 <Tank_Master> suprised?

13:32 <Nickuwo> let down :(

13:34 <PovAddict> ...Never gonna give you up, never gonna let you down...

13:36 <Nickuwo> ...

13:36 <Romulus> <http://tinyurl.com/c6de45> (at encyclopediadramatica.com)

13:51 <RomW> Nickuwo: I think the assumtion is that if you want that configuration you assign the workunits to an app version where the only configuration for that app version is a GPU app

13:51 <RomW> configuration = app plan

13:51 <Nickuwo> ahh right on

14:01 <Nickuwo> it's all starting to make sense now...

14:32 *** stux|RC has joined #boinc

14:40 <Nickuwo> so why cant you describe boinc as "open source"? is it b/c you can't redistribute it?

14:40 <Nickuwo> or b/c David controls the code?

14:42 <RomW> I guess it all depends on how you define Open Source, as far as licenses are concerned it is Open Source

14:48 <PovAddict> Nickuwo: who says it's not?

14:49 <Nickuwo> thought I saw someone in here mention it wasn't. also wikipedia doesn't mention it as "open source" :)

14:49 <RomW> lol, I think he is mentioning your quote Pov, about removing the 'O' in BOINC

14:49 *** Aeternus has quit IRC

14:50 <PovAddict> &quotegrabs search BINC

14:50 <Romulus> PovAddict: #15: Isn't it about time we start referring to...

14:50 <Nickuwo> there does seem to be a "volunteers can freely contribute to code" stipulation that may or may not describe boinc....

14:50 <PovAddict> &quotegrabs get 15

14:50 <Romulus> PovAddict: <jasong> Isn't it about time we start referring to the program as BINC, since David Anderson seems to be making a joke of the word the O stands for? (Said by: jasong!n=jason@24.144.38.145; grabbed by PovAddict!n=nicolas@nicolas17-1-pt.tunnel.tserv3.fmt2.ipv6.he.net at 04:32 PM, March 11, 2009)

14:50 <PovAddict> well that's quite debatable

14:51 <PovAddict> as far as technicalities go, it's open source and it's free software

14:51 <Nickuwo> but anyway, I just didnt want to piss anyone off b/c im describing it that way in a paper im writing

14:51 <Nickuwo> good enough for me

14:51 <PovAddict> Nickuwo: you'll piss someone off if you say it's *not* open source

14:51 <Nickuwo> ill prly piss someone off either way

14:51 <Nickuwo> hehe

14:57 *** [B^S]renemayer has joined #boinc

15:09 <RomW> I think the one underlying truth about FOSS software that applies to all projects is that it is run by those with commit access in the source tree.

15:09 <MTughan> True.

15:10 <PovAddict> in distributed version control, everybody has commit access ;)

15:10 <RomW> to the source tree

15:10 <RomW> ops

15:11 <RomW> But, even then, the project leader is the only one that is concidered to have the authentic source

15:11 <PovAddict> yeah

21:35 <FreeLarry58> good for you RomW

21:35 <FreeLarry58> was down around Orlando around 1978/9 for schooling

21:36 * PovAddict has been to Disney

21:36 <FreeLarry58> was there when it first opened -- and got locked inside the park one friday night

21:37 <FreeLarry58> and yes some of the rides are so automated at that time they continued to operate even when park closed

21:47 <Nickuwo> hmm, i need to program a function f(x) that = 1 iff x = 1, and is 0 otherwise.... without if statements...

21:48 <Nickuwo> o wait nm

21:52 <Nickuwo> I find it remarkable that you seem to be able to do anything you can do with and if statement using boolean operators. thats cool

21:52 <Nickuwo> an if statement that is

21:53 <PovAddict> well, all an if statement does is execute what's inside if what's between the parenthesis is non-zero

21:54 <Nickuwo> right, just never thought of programming without them...

21:54 <PovAddict> all the comparison stuff is done by the operators

21:57 <Nickuwo> now if I could only get rid of for statements...

21:59 <PovAddict> o_o

22:00 <PovAddict> what are you doing?

22:00 <Nickuwo> writing a CUDA kernel

22:00 <PovAddict> to get rid of fors you need something fundamentally different

22:00 <Nickuwo> o ya?

22:00 <PovAddict> since you'd usually do all the iterations of the loop *at the same time*, in different GPU cores

22:01 <Nickuwo> hmm

22:01 <Nickuwo> not sure thats gonna fly here... lemme think

22:01 <Nickuwo> be messy

22:01 <PovAddict> otherwise you won't gain much performance from the GPU...

22:02 <Nickuwo> I think it'll be easier just to make sure all cores do the loop the same amount of times, just that some of them do nothing sometimes

22:02 <Nickuwo> ya, that should work..

22:03 <Nickuwo> this logic is getting complicated...

22:04 <PovAddict> http://en.wikipedia.org/wiki/Stream_processing

22:04 <Romulus> Title: Stream processing - Wikipedia, the free encyclopedia (at en.wikipedia.org)

22:06 <Nickuwo> all this if and for-quashing seems like something you could teach a compiler to do

22:07 <PovAddict> not really

22:07 <PovAddict> if all you do is remove all branching and looping, I doubt it's any faster than on a CPU

22:07 <Nickuwo> y

22:08 <PovAddict> because stream processors work in a different way

22:08 <PovAddict> in a CPU you have for(i=0; i<total_items; i++) { /* some code that processes array[i] */ }

22:09 <Nickuwo> ya

22:09 <PovAddict> in a GPU you make a kernel that processes a single item, then you tell the GPU to run it for every element of the array

22:09 <Nickuwo> right...

22:09 <PovAddict> and it would do hundreds of array elements at the same time

22:10 <PovAddict> if processing of one element depends on the result of the previous calculation, the algorithm is just not suited to GPUs

22:10 <Nickuwo> right, and the only reason it would crap out and do them sequentially is bc of divergence

22:11 <Nickuwo> ahh yes, i spose you cant teach a compiler about that easily

22:11 <Nickuwo> but rewriting ifs and fors seems like a different story

22:11 <Nickuwo> instead of if(x){do y}

22:12 <Nickuwo> if y is an assignment do y = y*x + y*!x

22:12 <Nickuwo> well

22:13 <Nickuwo> hopefully u get the point

22:13 <Nickuwo> mangled example :)

22:13 <XioNYC> Q: Are you repeating the same process upon every member of an array, or are you applying the same process to the set?

22:14 <Nickuwo> im repeating the same process on every member, although the member in this case is an array itself

22:16 <Nickuwo> every member takes a different amount of processing... but if I do this correctly, it should only take as long as the longest member... right?

22:16 <XioNYC> Not necessarily.

22:16 <PovAddict> gpu programming isn't easy

22:17 <Nickuwo> thats true

22:17 <Nickuwo> and if im misunderstanding something, please correct me... this stuff is interesting

22:17 <PovAddict> #cuda

22:17 <Nickuwo> im in there already, just thought you guys might know something i dont

22:18 <XioNYC> We know plenty that you don't.  It's just that what we know might isn't necessarily relevant.

22:18 <Nickuwo> okay...

22:18 <FreeLarry58> dang i was sure i save the winzip activation code i got a couple of years ago - but don't see it in the saved messages

22:19 <XioNYC> Reading between the lines somewhat, it might be more beneficial to switch languages/paradims.

22:19 <PovAddict> and you *can* use ifs in kernels, apparently
