Multi Core optimization
Olivier Tristan
I'm trying to thread on multiple cores the rendering done in a CoreAudio
callback (high/realtime priority thread) in a c++ application
First I tried using Intel TBB task_group which worked fine on Windows
but it had terrible performance on OSX with lots of switch_pri mentioned
in Instruments. (maybe related to the calling thread priority)
So I tried Grand Central Dispatch and it was a bit better but not
marvelous so I was wondering if there are some flag that are better
suited than DISPATCH_QUEUE_PRIORITY_HIGH
when used in a real time thread.
Or if there is a better solution to my problem :)
Thanks !
