mac pro with final cut pro

Hi everyone,
I just got a 12 core mac pro. I installed and started using final cut pro. I noticed that final cut is only using 2 out of the 12 cores. I am wondering if this is a software problem. Final Cut pro isn't capable of using all available cores. Last time final cut pro was updated it was built for dual core computers. Any thoughts? thanks,

Scott

mac pro, Mac OS X (10.6.4)

How can you tell how many cores it's using?

That's a good question. In the activity monitor I see that final cut pro is using 200% of cpu. I would think that means it is using 100% of core 1 and 100% of core 2. I might be wrong here. Thanks for the reply. I am very interested in finding out what is happening here.

I noticed that the other apps in final cut studio is doing the same thing. It looks like the apps aren't using all the cores.

And that is what I keep reading:

Apple's math is 100% per core rather than say 15% of system resources.

That it isn't not highly optimized at all for multicore world.

And, a core using 100% rather than being efficient is actually a sign of the opposite. The optimizations that worked in the past (pre-Nehalem) get in the way now, and even then it wasn't ideal (running in circles, thrashing a core, constantly asking, even having to wait to get code and data in/out of Ln caches.

Also, sometimes HT isn't really useful, but then you can't can you prioritize an app rather to use less threads and cores the way Task Manager will.

Did anyone try to use Premier CS5 on new Mac pro?
