multicore settings ?

[tanabarbier]

Hi everybody

I'm starting to work with usine, and I really enjoy this incredible software.

Here's my beginner question : what should I choose on the CPU setting that is in "setup" to optimize the use of my i7 cpu ?

I tried 4 cores and 8cores, but when I look at the performances with the "gestionnaire des taches windows" only 4 seem to be used by usine.

How could I make usine use all of the cores ?

thanks in advance !

try this for a bit more insight http://www.sensomusic.com/wiki/doku.php ... &s[]=cores

I set my i7 to 8 cores and for threads I'm still a bit confused, it seems to work most efficiently when I have the same number of threads as tracks, but I am honestly still confused about this setting.
In general, each track will use a separate core so I find it most efficient to to use as many tracks as I have cores (8)
About only 4 cores being used in the task manager, I noticed the same thing recently on one project but haven't taken the time to look any further. It's been awhile I haven't been deeply immersed...

(edit, minor typo)

Ok, thanks for the advices, I'll try this right away !

for info, This point will be simplified in the next major release (5.50)

When reading the updated manual there is one thing it does not say explicitly... Which thread processes the graphics engine? Is it always the same thread that runs the main process, or is it distributed among the threads also doing the tracks?
The reason I'm asking is that in the older versions one could choose where the graphics engine should be processed, and I can only get clean sound on my core 2 quad if the graphics engine is not processed by any of the cores also doing audio/tracks.
I hope it is kept alongside the main process. (I haven't updated yet so I haven't tried it)

And one more question: If I invest in a 6 core cpu and make a setup with 5 tracks, I guess setting nb-threads=6 will keep one core for the main process (and graphics?) and the other 5 cores for processing each track individually?

hello,

i will let senso answer more precisely , but yes the process is really simplified for the user in the last releases

And btw, remember you can have several version of Usine on your computer so feel free to test and tell us how it is for you..?
