I would love to see a SMP version of Crafty for the new dual G4 machines.
I haven't seen any documentation of the SMP interface, but I would guess it is
going to be based on the Unix SMP interface since OS X is based the BSD
microkernal.

Let me know what you find out.

I don't know if OS 9 supports SMP.  Does anyone else know?

On a related note:  When I get rich, I plan to get all the back issues of ICCA
Journal and get a dual G4 machine and convert Screamer or Ad_Hoc to SMP (with a
lot of help from my friends).  :)

By then, I hope the clock speed of the G4's is faster than 500 mhz.
