Foil 46 Some Major Hardware Architectures - Mixed

From Master Set of Foils for 1997 Session of CPS615 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 97. by Geoffrey C. Fox
Also have heterogeneous compound architecture (metacomputer) gotten by arbitrary combination of MIMD or SIMD, Sequential or Parallel machines.
Metacomputers can vary from 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
This is a critical future architecture which is intrinsically distributed memory as multi-vendor heterogenity implies that one cannot have special hardware enhanced shared memory
  • note that this can be a MIMD collection of SIMD machines if have a set of Maspar's on a network
  • One can think of human brain as a SIMD machine and then a group of people is such a MIMD collection of SIMD processors
