One of the great advantages of multiprocessor computers is the fact that main memory is
available to all processors on the system.
That's like saying one of the great advantages of a lamp is that it illuminates things. It's not just a great advantage, it's the definition.
What would make a system in which the various processors have separate memory a multiprocessor system?
1) It's simply stupid to write software that assumes this as it won't scale to distributed
It sounds like you're saying it's stupid to write software for multiprocessor systems because then it would be software for multiprocessor systems.
I'm actually a foe of multiprocessor systems. My experience makes me believe processors separated by TCP/IP, FCP, etc. links are more profitable for most things. But I can definitely see the advantages of SMP.
