Re: [linux-audio-dev] latency and P4 hyperthreading?

2003-06-04 Thread Taybin Rutkin
How does the P4 machine compare against itself with hyperthreading turned off? I'm not surprised that hyperthreading is slower than a true dual CPU setup. Two CPUs sharing their cache? That's got to increase cache misses. Taybin ---Original Message--- From: Fernando Pablo

[linux-audio-dev] MVC again

2003-06-04 Thread Juhana Sadeharju
Hello. It is still quite unclear to me how I actually would code the MVC type software. Can anyone give practical hints? Practical examples taken from existing software would be fine too. What open source software uses MVC? Most open source software seems to manipulate the model data in the GUI

How does the P4 machine compare against itself with hyperthreading turned off? The latency is fine (when booting into a up kernel). I did not run generic benchmarks for testing speed. There is a gain but it is not that much (from benchmarks I've seen on the web). I'm not surprised that

Linux' readiness for pro audio (was Re: [linux-audio-dev] HartmanNeuron)

2003-06-04 Thread Jay Vaughan
Knowing that you know the APIs of Mac OS X too, do you still see some things lacking in the current Linux APIs ? I think that the low-latency work being done in the kernel, the latest LADSPA work, and Jack work by Paul D, pretty much levels the playing field technology-wise. Same with driver

Well, theres the chameleon (sp?), but that isn;t a card, so wont lett you accelerate just inner loops. Its very nice, and it's rack mountable, which is a big plus. I just have to say that the Chameleon is a rack-hackers tool of choice and if any of you audio/Linux guys haven't had a chance to
