Today we see the following "CMOS Juggernaut" Architectures
|
|
SIMD: No commercial or academic acceptance except for special purpose military (signal processing) and commercial(database indexing) applications
|
|
Special Purpose: Such as GRAPE N-body machine which achieves a Teraflop today and a petaflop in a few years -- requires small memory and small CPU's
|
MIMD Distributed Memory:
-
Merging with Shared memory in tightly coupled systems
-
Growing importance with World Wide Web and MetaComputing
|
Shared Memory
-
Tera Computer is isolated interesting attempt to build UMA system
-
SGI (based on Stanford Work and merging Cray and SGI lines) and Convex will base high end on distributed shared memory which merges distributed and shared memory
-
Physically distributed but logically NUMA shared memory
