Looking at a couple of the things you ran across, I think you've already discovered some of the basic tradeoffs. Dual processor systems are often slightly slower clock speeds than the fastest single core processors. I've never been sure why this is, but I suspect it's amount of testing that goes in to development along with the additional complexity of dual (or more cores.) And your trouble with video doesn't surpise me a lot. I've got an early athlon MP system with a server motherboard (Tyan.) The video options never seem to be as complete on server systems. Also, I saw some commments in your Anandtech thread about video options. Note that even the nvidia cards with series numbers in the x200 (5200 for example) are rather poor performers. I would not bother making a special effort to get a x200 nvidia card working for OpenGL. If a pci-x card with a x600 or x800 number (6600, 6800, or 7800 on up) could be made to work, then it might be worth it. Otherwise I would not bother trying to get the OpenGL support setup for cinelerra. One comment on performance: In my recent builds and testing on AMD X2 64bit suse 10.2, I found that optimizing the cinelerra build was of no benefit, and sometimes was a penalty. If you are building cin yourself, and have used any of the additional optimization flags we've covered here before, you may get better performance bt removing them from your build on FC6. -- Kevin ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
Re: [CinCVS] Cinelerra performance on new quad-core xeon box
Vale, Thanks for the input. You'll have to renderfarm them and let us know how your performance is! :) Right now, sad to say I'm using the motherboard video of 16MB. It's ugly. This server class machine is picky about video cards and I can't use the NVidia card I bought for it. So right now and maybe for the future, I am going to forego OpenGL. Though surprisingly, I still get 30fps in the compositor on HDV content (without effects present). And cinelerra seems very stable. I will put it through its paces with my current project and let the list know how I do. The one nagging issue I do have is that Cinelerra does not seem to be utilizing the processors to 100% at all times..hangs around 30% mostly. I will work through this project and write up an analysis after I am done. But yes, life is good! :) scott On Sun, 2007-09-30 at 14:32 +0200, Valentina Messeri wrote: > "Scott C.

Hi Kevin, Thanks for the comments! On Sun, 2007-09-30 at 11:56 -0400, Kevin Brosius wrote: > rather poor performers.

However, after thinking about it awhile, OpenGL really only effects playback performance, which already seems pretty good on the octo-core, even with only 16MB video memory. What I might do is purchase a VisionTek Radeon x1550, which is known to work with the motherboard. That will give me back my dual monitors at least! :) > One comment on performance: In my recent builds and testing on AMD X2 > 64bit suse 10.2, I found that optimizing the cinelerra build was of no > benefit, and sometimes was a penalty.

I have been building cin from CVS source myself; however, I did not tweak any of the optimization flags. I just let ./configure do its thing. I have the whole configure/make/compile chain output, if interested. I guess my first question would be: Though I see that Cinelerra is not using 100% of the processors while editing or rendering, is this really an issue? I tend to think it is, and Graham and I talked about possible memory or front side bus bottlenecks. If it is, do you know where I might look to diagnose such an issue? In the meantime, I will do some googling to find any relevant procedures. looking forward to your opinion, scott ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
[CinCVS] What Does Cinelerra-CVS Need?
I will be going to an internal Open Source summit here at Sun in a few weeks. I plan on telling people about my podcasts and Cinelerra is surely going to come up. IF (no promises here) I get the chance to ask for help for Cinelerra what should I ask for? What does this community need that open source developers and community members at Sun could provide? -- Thanks, Aaron Newcomb http://www.thesourceshow.org http://www.opennewsshow.org ___ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
[CinCVS] More Tracking
hSince we are talking about tracking and stabilisation, I will add an extra layer: the mjpeg tools have a y4mstabilizer that is working nicely for me. However it needs a color sampling of 444 which may not be available to everybody. I use it before importing in Cinelerra. Cheers E
