20150413 07:39:43 <eclesia> good morning
20150413 08:38:20 <bruce-> hello!
20150413 08:39:09 <bruce-> I have an interesting problem with a dual quadro k2000/mosaic setup
20150413 08:40:10 <monsieur_max> nice setup you got there :)
20150413 08:40:12 <bruce-> I currently have a program running in 3840x2160 with an opengl2 context on it
20150413 08:40:19 <bruce-> it runs perfect
20150413 08:40:48 <bruce-> now I upgraded all the rendering code to opengl3, it works fine on everything I tested it on
20150413 08:41:02 <bruce-> except for the dual quadro setup
20150413 08:41:35 <bruce-> it is really slow (as in seconds per frame)
20150413 08:42:17 <bruce-> has anyone run into similar problems?
20150413 08:42:59 <bruce-> it is a bit problematic that I don't have the setup at the studio
20150413 08:44:03 <bruce-> I did manage to get my hands on a machine with a single quadro graphics adapter but I have not tested if I have similar problems on that machine
20150413 08:47:56 <bruce-> (remind me to always spec backup machines for big projects like this)

20150413 09:14:27 <zubzub> dual quadro?
20150413 09:14:36 <zubzub> as in sli stuff?
20150413 09:14:44 <zubzub> windows or linux?
20150413 09:15:13 <zubzub> afaik linux doesnt have sli support
20150413 09:15:20 <zubzub> but that knowledge might b outdated
20150413 09:20:00 <bruce-> windows
20150413 09:20:25 <bruce-> I really wouldn't dare touching linux for these kind of setups
20150413 10:43:39 <bruce-> ah, it is also messed up on a single board setup
20150413 10:44:05 <bruce-> turns out it is caused by a second thread that is used for asynchronous image loading
20150413 10:48:43 <bruce-> that thread also performs texture unloading, for that to work on Intel HD4000 I have to issue glClear(). there is no call to sleep() in that thread so it was a bit agressive
20150413 10:49:19 <bruce-> still, it works on all other setups I have without problems
