| 02:29.54 | IriX64 | Maloeran, I wasn't really kidding about that don't start the thread bit, if it gives you hassle incorporate the code into whatever thinks it needs to start a thread. |
| 02:30.44 | IriX64 | forr what its worth :) |
| 02:34.24 | Maloeran | Threads shouldn't be avoided, they are used to distribute the work over multiple processors |
| 02:35.24 | IriX64 | not saying avoid them bit if one particular piece of code is giving you grief why fight it. |
| 02:38.11 | Maloeran | It's fine, just OSX doing things a bit differently, no big deal |
| 02:41.43 | ``Erik | heh |
| 02:48.04 | louipc | what's the ideology behind that feature? |
| 02:49.42 | Maloeran | That ia32's largest data type is "double", which is 8 bytes, therefore stacks only require 8 bytes alignment |
| 02:50.51 | Maloeran | Then SSE arrived, which required 16 bytes. The glibc and kernel crowd kept putting the blame on the other camp, I think it got fixed at some point |
| 02:52.25 | Maloeran | Compilers like Intel would align the stack of every function dynamically whenever SSE was used to work around that issue |
| 02:59.15 | louipc | wowzers this processor mumbo jumbo is beyond me |

| 23:22.29 | IriX64 | btw my little x works very well. |
| 23:22.52 | IriX64 | has to or i would not be able to run BRL-CAD. |
| 23:23.47 | IriX64 | wonders too. |
| 23:24.33 | ``Erik | ok |
| 23:24.38 | ``Erik | run on ppc. |
| 23:24.43 | ``Erik | or rs6k. |
| 23:24.45 | ``Erik | or h9k |
| 23:24.55 | ``Erik | or vax or pdp11 or m68k or ... |
| 23:25.12 | IriX64 | now you're speaking my langugae |
| 23:25.27 | IriX64 | pdp8s best machine ever. |
| 23:26.03 | ``Erik | or support hundreds of concurrent users |
| 23:26.11 | IriX64 | doing a no debugging build want to see how fast havoc photon maps. |
| 23:26.30 | ``Erik | or provide services to the internet with no antivirus software chewing cycles and not get infected or cracked |
| 23:26.43 | IriX64 | huh? |
| 23:27.19 | IriX64 | ``Erik i respect you're opinion no matter how wrong you may be ;) |
| 23:27.34 | ``Erik | <-- doens't think he's all that wrong O:-) |
| 23:27.50 | IriX64 | heh neither do i :) |
| 23:28.43 | ``Erik | and photon mapping is a two phase operation... it raytraces as fast as it does with no lighting... and the photo map pass totally depends on how many photons you specify and a few other parameters |
| 23:29.10 | ``Erik | path tracing seems a bit more interesting, though... have you managed to get adrt to build? it has something in it called "rise" which is pretty neat |
| 23:29.16 | IriX64 | sure but you can get a guesstimate if you leave all the settings the same. |
| 23:29.34 | IriX64 | missing sdl gotta tend to that. |
| 23:29.40 | ``Erik | libsdl.org |
| 23:29.44 | IriX64 | ty |
| 23:33.19 | IriX64 | yum thanks ``Erik i'll let you know if I ever get it going btw is it fraught? |
| 23:34.26 | IriX64 | you're supposed to say "there's just no arguing with a word like fraught" :) |
| 23:35.25 | IriX64 | python is also needed. |
| 23:36.38 | ``Erik | ... yes, sdl and python are (sorta) needed, though I think rise itself doesn't use either |
| 23:36.58 | IriX64 | getting python 2.5 now. |
| 23:37.36 | ``Erik | n/m, rise observer uses sdl |
| 23:37.44 | IriX64 | ah |
