What will happen to threads and multiprocessing in OS X? I assume the
Thread Manager will remain around as Carbon, but will other (UNIX
standard) multi-processing APIs like OpenMP be available as well?

If you're writing Cocoa apps, they get a lot easier to deal with. Check
out the documentation for the NSThread class.

You'll have all the multiprocessing services of Unix available to you
(under Cocoa). Programs will be able to call neat things like fork(). :)

But under Carbon?

There is Multiprocessing SDK ver 2.1 at Apple Dev website,
http://developer.apple.com/sdk/. According the documentation, it will be
supported in Mac OS 8.6 and above and later via Carbon. It seems to be a
replacement for Thread Manager.

I have use the SDK and found it to be working at Mac OS 9 (non Carbon)
running on my iMac. It is really amazing to see it doing preemptive
multitasking on a classic Mac OS. My only problem is I do not have decent
debugger ( I am using CW5) which can debug MP task. I am not familiar
MacBugs 6.6 (suggested by the MP SDK), I really wish there is a better
way of debugging.

Write MW...@metrowerks.com and ask about an MP safe debugger. They may
send you one.

I have asked MWRon sometime back, according to him the
debugger is not available yet. I suspect it will be only available on
CW6 or when MacOS X is ready.

Have anyone done any programming on Carbon using MP SDK ?

I hope to port my current program (using MP) to Carbon sooner or
later.

Actually, Mach-O is the *Mach* object file format, and you won't find it
on most other UNIX implementations. On Linux, for example, the most
common executable format is the ELF binary.

Doesn't MacOS 9 include a CarbonLib? Admittedly, I assume it's not the
full MacOS X version, but I'm pretty sure it's there...

Just wondered if it still works under 8.x, without Carbon installed...
