[01:10] hi! [01:11] did the most recent kernel published for karmic contain changes in the dvb susbsystem? just reinstalled some external, not yet in the main tree, driver for my dvb-s device and /dev/dvb/ is gone but /dev/dvb0.* is there instead === asac_ is now known as asac === corge is now known as Guest56801 === Daviey__ is now known as Daviey [12:41] hi.. [12:42] is it possible to make a quad core processor work as combined single core ?/ [12:42] my software runs only using single core.. it is not built for multi core.. [12:51] it shouldn't make a difference, the app should just work [12:51] speed.. [12:51] my each core is off 900mghz [12:52] it only uses 900 :( [12:52] you'd have to change your app to use threading for that [12:53] i am using aqsis, an open source renderman renderer. [12:53] its the only one .. :( [12:54] you think it is not possible at kernel level to make the entire operating system think quad core as one processor? [12:54] i think, its crazy idea.. [12:55] mohanohi: no you can't [12:56] alex_joni: oh ok.. thanx for the info :) [12:56] if there's only one process, that runs on one processor [12:56] if you have 4 processors (cores), then you need a multi-threaded app to take advantage of that [12:57] ok.. [12:57] i think i have to submit the job 4 times.. [13:04] submitting the job 4 times will start 4 _different_ processes that don't share the data [13:05] mohanohi: to share data, the app needs to be multi-threaded [13:05] amitk: its not like that.. [13:06] rendering a batch of 10 frames x 4 [13:06] yeah shading of data is not done.. but it utilizes my all cores.. [13:06] hope the developer makes it multi-threaded.. === MTeck-engaged is now known as MTecknology === yofel_ is now known as yofel [16:24] hello, i read that many usb devices are flawed and that kernel 2.6.8 has fixed this (worked around it). [16:24] Where can I find more information. [16:24] I hope to patch 2.6.4-16-rtai to allow same fix. [17:56] there are rumors that 2.6.32 has ext4 bug/issue that impacts postgresql and apache performance [17:56] this is the commit: [17:56] http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5f3481e9a80c240f169b36ea886e2325b9aeb745 [17:57] (haven't tested it yet) [18:55] anyone aware of upstart changes which would prevent booting older kernels? [18:55] * mcgrof pokes at code [19:04] mcgrof, not sure about upstart, but newer udev won't work with older kernels [19:07] johanbr: oh I see thanks [19:07] yeah the upstart README indicatest kernels >= Linux 2.6.24 are supported [19:07] johanbr: what about udev is screwy with older kernels [19:08] I don't remember the details, unfortunately...
