Does anyone know of any multiprocessing programming tutorials using either ObjC or Java?

Thanks,

I think if you just run things as threads then they will be multiprocessor aware by default. I'm not entirely sure though.

Yes, Java uses native threads, and takes advantage of MP machines automatically. Sun has several tutorials on threads at http://java.sun.com, though they don't discuss MP specifically.

Actually, I was hoping to find some code specifically geared towards the G4 MP using OSX. I have done thread programming before, so the theory is understood.

Like Angus and JavaMac are saying, if you write multithreaded code the OS can schedule different threads on different CPUs without you having to do anything else. So what kind of information are you looking for for G4's specifically?

The assembly level coordination instructions (unnecessary if you use a higher level like Java, mutexes, NSLock)? Specifics about G4 cache coherency / cache size / etc to try to optimize your app to avoid cache aliasing during multiprocessing? Altivec code, maybe?
