04:02:58 #corewars: < bvowk_> hrm
04:03:09 #corewars: < pkhuong-> ?
04:03:33 #corewars: < bvowk_> hey pk
04:03:35 #corewars: < bvowk_> how's it going?
04:03:42 #corewars: < pkhuong-> btw, for cache performance, is it better to separate code (indirect calls) and data (pointers)?
04:03:50 #corewars: < pkhuong-> working on some vulgarisation articles
04:09:21 #corewars: < bvowk_> pk: not sure, I generally don't have a choice, either my code is way too big to put near my data, or my data is massive and my code is very small
04:09:30 #corewars: < bvowk_> so either way my cache is mostly useless
04:10:07 #corewars: < pkhuong-> lol k
04:10:23 #corewars: < pkhuong-> and if i'm going to change the pointers often, does it make a difference?
04:11:16 #corewars: < pkhuong-> i'm thinking that at least if the modified data is away fromt he constant code, (I) cache misses will be a bit less frequent.
04:11:16 #corewars: < bvowk_> prolly not
04:12:11 #corewars: < bvowk_> if you can prefetch, you might want to apply that
04:12:26 #corewars: < bvowk_> it makes a big difference with some of my data intense code
04:12:30 #corewars: < pkhuong-> how do i do that on x86?
04:12:37 #corewars: < pkhuong-> and "prefetch?"
04:12:46 #corewars: < bvowk_> read the amd optimization guide
04:12:54 #corewars: < pkhuong-> amd only?
04:12:56 #corewars: < bvowk_> they've got some nice examples and rules of thumb
04:12:59 #corewars: < pkhuong-> k
04:13:09 #corewars: < bvowk_> I've only ever used it on AMD, but doubt its only amd :)
04:13:52 #corewars: < pkhuong-> the modified data is usually modified just before being used, so i guess modifying -> prefetch -> execution would be good.
04:14:00 #corewars: < pkhuong-> *adds to todo list*
04:23:46 #corewars: < bvowk_> I'm getting new boards :)
04:23:57 #corewars: < bvowk_> they're going to be asus boards with sysconnect gige

10:57:14 #corewars: < Torquay1> No CW?
10:57:46 #corewars: < Mizcu> so far no
10:57:54 #corewars: < Torquay1> Hmmm... stupid Usenet.

10:58:21 #corewars: < Mizcu> whee
10:59:56 #corewars: < Torquay1> Anything new?
11:01:26 #corewars: < Mizcu> mmm..    CW89!
11:01:42 #corewars: < Torquay1> Gotta go.

23:38:27 #corewars: < Roy> hi
23:38:57 #corewars: < joonas> hi roy
23:39:50 #corewars: < Roy> just got my gridwars t-shirt :) yay
23:40:05 #corewars: < joonas> cool.
23:40:12 #corewars: < joonas> how did the competition go in the end?
23:41:15 #corewars: < Roy> I was eliminated the first round, in the last round the 2 best warriors where facing eachother, one was GA optimized and one was pure nonGA, the GA optimized was much much better and made a quick end
23:41:43 #corewars: < joonas> how did Paul Kline do?

23:43:15 #corewars: < Roy> Paul got second place with his nonGA warrior
23:44:04 #corewars: < joonas> you'll appreciate this: http://treefern.apana.org.au/~foobar/Revenge-Of-Mouse.gif
23:44:13 #corewars: < joonas> wow.
23:44:51 #corewars: < Roy> Robert Macrea faced Marks warriors in the first round, so was soon out of the comp
23:45:19 #corewars: < Roy> Mark was the winner with his GA optimized warrior, using a lot of communication, very hightec
23:45:33 #corewars: < joonas> sounds interesting
23:46:08 #corewars: < Roy> It IS very intresting :) I don't know why other cw programmers joined in
23:46:26 #corewars: < Roy> *didn't
23:46:34 #corewars: < joonas> sorry to hear about Robert.  why didn't they do round-robin like everyone knows is best?
23:47:07 #corewars: < joonas> after all, they're donating an HP cluster so it can't be lack of computah powah
23:47:21 #corewars: < Roy> The first rounds are group battles (multiwarrior) and it is now indeed VERY unfair
23:47:53 #corewars: < Roy> Better mixed groupwarriors would be more fun yes, they are discussing ways to do that on the forum
23:47:55 #corewars: < joonas> yes, you mentioned the MW thing before and it does sound a bit odd to have two very different envs.
23:48:47 #corewars: < Roy> They also run ONE round, the third/fourth place was a very very lucky hit for the nr. 3, the next 100 times that same match was run the other warrior won
23:49:05 #corewars: < Roy> So that guy feels a bit stolen..
23:49:07 #corewars: < joonas> This is a funny one: www.mentalsoup.com/foobar/images/FooBar13.jpg
23:49:14 #corewars: < joonas> ONE ROUND?
23:49:20 #corewars: < joonas> yeach
23:49:22 #corewars: < Roy> Yup... :(
23:49:51 #corewars: < joonas> even the first CW tournament had, IIRC, 5 rounds.
23:50:51 #corewars: < joonas> sorry, I meant: http://www.mentalsoup.com/foobar/
23:50:52 #corewars: < Roy> Heh, thats why I'm currently pointing everything I say to Corewars, hopefully some of those good guys will pick up CW too :)
23:51:35 #corewars: < Roy> Foo Bar :)
23:51:43 #corewars: < joonas> be sure to point out the difference from walter's corewars thing.
23:52:02 #corewars: < joonas> mental soup too
23:52:07 #corewars: < Roy> Walters Corewars..?
23:52:09 #corewars: < joonas> :)
23:52:19 #corewars: < Roy> you mean the FORK thingy..?
23:52:20 #corewars: < joonas> uhm... corewars.sourceforge.net
23:52:32 #corewars: < Roy> Ah yes, no, I pointed them to Fizmo's page and koth.org
23:53:57 #corewars:  * joonas has been compressing images all day
23:54:10 #corewars: < Roy> Heh...why?? :)
23:54:26 #corewars:  * Roy has been programming in Java whole day...bleh
23:54:36 #corewars: < joonas> bleh
23:54:42 #corewars: < joonas> what were you programming?
23:54:58 #corewars: < Roy> I have to create a ordersystem...in one week :(
23:55:05 #corewars: < joonas> what's that?
23:55:07 #corewars: < Roy> (For school)
23:55:30 #corewars: < joonas> I mean what does an ordersystem do?
23:55:38 #corewars: < Roy> Just a program where a company call fill in Orders and then create management information
23:55:49 #corewars: < joonas> ah
23:56:24 #corewars: < Roy> Putting all the orders in a database etc...but there are a few hard things to program
23:56:54 #corewars: < joonas> there always is :(
23:57:05 #corewars: < Roy> Big SQL queries, allowing people to edit order information, making it print, etc etc
23:58:59 #corewars: < joonas> I have a new hobby for the times when I'm waiting for some long job to finish:  
23:59:09 #corewars: < joonas> random googling using images.google.com
23:59:15 #corewars: < Roy> heh
23:59:40 #corewars: < Roy> www.b3ta.com -> My favourite time consuming page (see the forum)
23:59:41 #corewars: < joonas> their "moderate safe search" is pretty effective even.
