BTW cos its vp smp, you could have a cluster of alpha, mips, ppc, intel
etc boxes load shareing the same software processess.

Well vpcode like most asm (except on special vector processors), is
sequential, as is the C/C++ and Java code is generated from. However with
a second cpu the kernel should migrate processes out to the lighest loaded
cpu, so if you have to 3dfx demos running in two windows, and the window
manager/gfx subsysm is threaded (sorry lightweight processed) enough then
each window should be updated by a diffrent cpu.
If i am just talking rubbish ignore me,..
