I am no expert. But aren't the two architectures above already built 
from factory ? Both shared memory and distributed shared memory basically
are similar to each other (single shared space address). May I ask why
you choose shared memory architectures ? It seems to me that few 
computer factories manufacture them now. The popular model at present is 
clustering of workstations (COWs). It is scalable, cheaper, and works
for heterogenous computers as well. -sk
