Foil 31 3 Major Basic Hardware Architectures

From Second set of lectures on CPS615 Parallel Computing Overview CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox *

MIMD Distributed Memory
MIMD with logically shared memory but perhaps physically distributed. The latter is sometimes called distributed shared memory.
SIMD with logically distributed or shared memory
One interesting hardware architecture .........
  • Associative memory - SIMD or MIMD or content addressable memories ..... whose importance deserves further study and integration with mainstream HPCCI
Also have heterogeneous compound architecture (metacomputer) gotten by arbitrary combination of the above.
  • Metacomputers can vary full collections of several hundred PC's/Settop boxes on the (future) World Wide Web to a CRAY C-90 connected to a CRAY T3D
