[01:10] <freinhard> hi!
[01:11] <freinhard> 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
[12:41] <mohanohi> hi..
[12:42] <mohanohi> is it possible to make a quad core processor work as combined single core ?/
[12:42] <mohanohi> my software runs only using single core.. it is not built for multi core..
[12:51] <amitk> it shouldn't make a difference, the app should just work
[12:51] <mohanohi> speed..
[12:51] <mohanohi> my each core is off 900mghz
[12:52] <mohanohi> it only uses 900 :(
[12:52] <amitk> you'd have to change your app to use threading for that
[12:53] <mohanohi> i am using aqsis, an open source renderman renderer.
[12:53] <mohanohi> its the only one .. :(
[12:54] <mohanohi> you think it is not possible at kernel level to make the entire operating system think quad core as one processor?
[12:54] <mohanohi> i think, its crazy idea..
[12:55] <alex_joni> mohanohi: no you can't
[12:56] <mohanohi> alex_joni: oh ok.. thanx for the info :)
[12:56] <alex_joni> if there's only one process, that runs on one processor
[12:56] <alex_joni> if you have 4 processors (cores), then you need a multi-threaded app to take advantage of that
[12:57] <mohanohi> ok..
[12:57] <mohanohi> i think i have to submit the job 4 times..
[13:04] <amitk> submitting the job 4 times will start 4 _different_ processes that don't share the data
[13:05] <amitk> mohanohi: to share data, the app needs to be multi-threaded
[13:05] <mohanohi> amitk: its not like that..
[13:06] <mohanohi> rendering a batch of 10 frames x 4
[13:06] <mohanohi> yeah shading of data is not done.. but it utilizes my all cores..
[13:06] <mohanohi> hope the developer makes it multi-threaded..
[16:24] <tom3p> hello, i read that many usb devices are flawed and that kernel 2.6.8 has fixed this (worked around it). 
[16:24] <tom3p> ﻿Where can I find more information.
[16:24] <tom3p> ﻿I hope to patch 2.6.4-16-rtai to allow same fix.
[17:56] <ivoks> there are rumors that 2.6.32 has ext4 bug/issue that impacts postgresql and apache performance
[17:56] <ivoks> this is the commit:
[17:56] <ivoks> http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=5f3481e9a80c240f169b36ea886e2325b9aeb745
[17:57] <ivoks> (haven't tested it yet)
[18:55] <mcgrof> anyone aware of upstart changes which would prevent booting older kernels?
[18:55]  * mcgrof pokes at code
[19:04] <johanbr> mcgrof, not sure about upstart, but newer udev won't work with older kernels
[19:07] <mcgrof> johanbr: oh I see thanks
[19:07] <mcgrof> yeah the upstart README indicatest kernels >= Linux 2.6.24 are supported
[19:07] <mcgrof> johanbr: what about udev is screwy with older kernels
[19:08] <johanbr> I don't remember the details, unfortunately...
[19:19] <mcgrof> johanbr: ok thanks though I'll ask Mr google
