[Bf-committers] openmp

[Jeroen Bakker]

Hi Rafael,

please be aware that there is a project that makes the whole compositor 
multi-processor (and multi-device) aware. Any development with the 
purpose to submit it back to trunk would not be worth the investment.
The compositor project is located on 
http://ocl.atmind.nl/doku.php?id=design:proposal:compositor-redesign
Here you can find details about what the ideas are. If you want to learn 
more about the project, you can contact me.

I have did some tests with openmp on the old compositor, but the 
speed-gain was limitted due to system behaviour.

Greetings,
Jeroen
