20150628 07:09:41 * monsieur_max (~maxime@anon) has joined #jogamp
20150628 08:27:27 <xranby_GTX580> good morning
20150628 08:54:31 * elect (~elect@anon) has joined #jogamp
20150628 10:38:30 * Eclesia (~eclesia@anon) has joined #jogamp
20150628 10:38:41 <Eclesia> plop
20150628 10:41:40 <xranby_GTX580> Eclesia: plip!
20150628 10:41:50 <Eclesia> hi
20150628 10:43:09 <Eclesia> I think my gc is half-dead, start seeing artifacts, psychedelic squares and lines when running 3d apps like blender :x
20150628 10:43:25 <xranby_GTX580> Eclesia: gc as in graphics card or garbage collector?
20150628 10:44:13 <Eclesia> does garbage collector produce psychedelic squares on the screen ?
20150628 10:44:23 <Eclesia> graphic card of course ...
20150628 10:45:18 <xranby_GTX580> Eclesia: this reminds me, deep learning neural networks can halucinate very nice psychedelic effects!
20150628 10:46:08 <xranby_GTX580> i also recall that if I use the latest nvidia drivers on a system running an older version of xorg i also see a lot of interesting lines
20150628 10:46:16 <Eclesia> xranby_GTX580: do you have the specification for brain-shaders ?
20150628 10:47:14 <xranby_GTX580> Eclesia: the closest implementation of a GPU optimized brain is http://vision.princeton.edu/pvt/GoogLeNet/
20150628 10:48:11 <xranby_GTX580> i have not seen a "shader" implementation
20150628 10:49:07 <xranby_GTX580> to summarize: about a week ago research was published how to run a trained neural network backwards to make it over interpret images
20150628 10:49:36 <xranby_GTX580> http://googleresearch.blogspot.se/2015/06/inceptionism-going-deeper-into-neural.html
20150628 10:50:10 <xranby_GTX580> a new word was coined "inceptionism"
20150628 10:52:10 <xranby_GTX580> http://www.twitch.tv/317070 <- a week later some people created a T live twitch stream that reproduced the research ->plays Large Scale Deep neural net (users can shout suggestions what the net should dream about)
20150628 10:53:28 <xranby_GTX580> this blog describe the work to create the live version seen in the twitch stream http://317070.github.io/LSD/
20150628 11:18:01 <elect> xrandy, let me guess
20150628 11:18:09 <elect> gxt580 on your pc? ^
20150628 11:18:11 <elect> ^^
20150628 11:33:10 <xranby_GTX580> yes GTX580 is a quite high performance nvidia card from 2011
20150628 11:33:50 <xranby_GTX580> that you can obtain for 100$ on second hand market today
20150628 11:34:45 <elect> what did you have before
20150628 11:34:50 <elect> ?
20150628 11:35:19 <xranby_GTX580> only arm SoC chips and an old AMD HD 4800
20150628 11:35:38 <xranby_GTX580> i swim in low end GPU's
20150628 11:36:10 <xranby_GTX580> i am a fan of making the most out of the low end tail of hardware
20150628 11:36:25 <elect> me too
20150628 11:36:28 <elect> I have a 680
20150628 11:36:45 <elect> not that old but also not that new
20150628 11:41:02 <Eclesia> I have the oldest then : gtx 460 ^^
20150628 11:42:54 <xranby_GTX580> Eclesia: which driver do you use and in combination with which xorg?
20150628 11:43:27 <xranby_GTX580> i think the psycadelic effect may be explained if you use the latest nvidia drivers, they have dropped support for older gtx cards
20150628 11:43:43 <Eclesia> I didn't update
20150628 11:44:22 <xranby_GTX580> lets see... .. .. 460 should still be supported
20150628 11:44:26 <Eclesia> driver 340.76
20150628 11:44:57 <xranby_GTX580> which xorg?
20150628 11:45:00 <Eclesia> 1.17.1
20150628 11:49:40 <xranby_GTX580> Eclesia: can you screenshot the psycadelic effects that you experience?
20150628 11:51:40 <Eclesia> nope, crash shortly after
20150628 11:54:11 <Eclesia> looks like this : http://i.ytimg.com/vi/qVkE04C61Ys/maxresdefault.jpg
20150628 11:57:00 <xranby_GTX580> some bugreports points finger at the Compiz compositor -> https://bugs.launchpad.net/compiz/+bug/1288747 -> "Being an upstream maintainer of Compiz, I would absolutely love to accept the patch. However, somehow Compiz falls under the CLA and we are still trying to get Nvidia (who provided the patch) to agree to it. Trust me when I say there have been ongoing discussions to get this in. We are dealing with glacial p
20150628 11:58:02 <xranby_GTX580> so nvidia has provided a patch for compiz but compiz cant accept the patch due to how they run their project and require people to sign contributor agreements
20150628 11:58:16 <xranby_GTX580> can someone please fork compiz :)
20150628 12:02:43 <Eclesia> forget about compiz, rewrite xorg in public domain

20150628 15:44:24 <eclesiaSafeMode> pfiu, finaly found something that doesn't crash in a few minutes :/
20150628 15:45:05 * rmk0 pokes it with a stick
20150628 15:46:02 <eclesiaSafeMode> so, are there any spirv gc already sold ? ^^
20150628 15:48:19 <rmk0> all of them!
20150628 15:48:31 <rmk0> don't think anyone has a driver that consumes spir-v yet, though
20150628 15:55:42 <eclesiaSafeMode> ouch ddr2 is pretty expensive :/
20150628 15:56:21 <rmk0> yep
20150628 15:56:54 <eclesiaSafeMode> I'll stay with 4go until I upgrade the motherboard then...
20150628 15:58:01 <rmk0> imagine people will be moving to DDR4 by next year
20150628 15:59:41 <eclesiaSafeMode> thing is most of the time you always have to upgrade motherboard+cpu+ram
20150628 16:01:26 <rmk0> urhur
20150628 16:07:20 <rmk0> i need to replace my desktop for the same reason as you... bad gpu
20150628 16:07:30 <rmk0> got green dots all over the screen
20150628 16:08:06 <rmk0> hesitant to buy any hardware now as i don't want to buy intel and amd don't make anything consistently faster than the i7 i have
20150628 16:08:54 <rmk0> the motherboard is also almost dead... goes insane when any usb device is plugged in
20150628 16:09:13 <rmk0> can't replace the motherboard for a reasonable price as noone produces any with the right socket type now
20150628 16:09:59 <eclesiaSafeMode> rmk0: I don't need more cpu power for what I do (phenomII x4 3.2Ghz). the gpu was ok too until yesterday (gtx460). just the ram which is a bit low (4go)
20150628 16:10:23 <rmk0> oh, it's not that i need more, i just don't want to spend money on something that's "worse" than what i already have
20150628 16:11:00 <eclesiaSafeMode> rmk0: it would be cool if they start selling correct performance barebones with arm cores
20150628 16:11:06 <rmk0> seriously dislike intel's "let's create a new socket type once a month"
20150628 16:14:35 <eclesiaSafeMode> unlike the latest amd fx8000+ which are still compatible with my 5years old AM3 socket
20150628 16:16:00 <rmk0> think i'll wait for this: https://en.wikipedia.org/wiki/Zen_(microarchitecture)
20150628 16:33:23 <eclesiaSafeMode> pci express 3.0 works on 2.0 if I'm right ?
20150628 16:35:26 <rmk0> you can put a pci express 3.0 device into a 2.0 socket
20150628 16:35:56 <rmk0> hehe, i've seen "guides" online where people saw the teeth off graphics cards to get them to fit into tiny x16 slots
20150628 16:36:02 <rmk0> they still work, just horrendously slowly
20150628 16:36:10 <eclesiaSafeMode> ^^
20150628 16:40:03 * elect (~elect@anon) has joined #jogamp
20150628 16:44:56 <eclesiaSafeMode> is 4go mem on a gc really that usefull ?
20150628 16:45:54 <rmk0> if you've got 4gb of meshes and textures!
20150628 16:47:32 <eclesiaSafeMode> I don't even have 4gb of mesh on disk !
20150628 16:47:40 <rmk0> hehe
20150628 16:48:01 <rmk0> don't forget to count framebuffers
20150628 16:53:24 <eclesiaSafeMode> well here goes : gtx960(2gb) 200€ , gtx770(4gb) 270€ gtx970(4gb) 340€
20150628 16:55:41 <eclesiaSafeMode> hard choice ...
20150628 17:01:23 <eclesiaSafeMode> rmk0: what would you choose ?
20150628 17:02:25 <eclesiaSafeMode> and don't answer Intel IGP :p
20150628 17:43:54 <eclesiaSafeMode> rmk0: and one short version of a gtx970 on the way ^^
20150628 17:49:26 <elect> dont get 970
20150628 17:49:32 <elect> it has a mem problem
20150628 17:51:36 <eclesiaSafeMode> you mean the 3500memory limit ?
20150628 17:52:26 <eclesiaSafeMode> elect ?
20150628 17:53:46 <rmk0> i don't know much about nvidia hardware
20150628 17:54:12 <rmk0> given their obsolete stance on "preserving their intellectual property", i've not bought any of their hardware
20150628 17:54:37 <rmk0> i owned one nvidia card once, and then they revoked the drivers and made it more or less useless overnight
20150628 17:55:36 <rmk0> i probably would have gone for the 970 too
20150628 17:56:00 <eclesiaSafeMode> hm I never had issues in the past, geforce 256, geforce 2, mx400, ti, gtx 460. so far so good they all lasted several years
20150628 17:56:34 <rmk0> you won't have an issue until they decide it's time to upgrade
20150628 17:56:44 <rmk0> they'll be less able to do that as nouveau improves

20150628 18:15:26 <eclesiaSafeMode> the gtx970 memory seems to be really a corner case :http://www.extremetech.com/extreme/198223-investigating-the-gtx-970-does-nvidias-penultimate-gpu-have-a-memory-problem
20150628 18:15:39 <eclesiaSafeMode> no big worries here
