Foil 8 Some Major Hardware Architectures - Mixed

From CPS615-Lecture on Computer Architectures and Networks Delivered Lectures of CPS615 Basic Simulation Track for Computational Science -- 12 September 96. by Geoffrey C. Fox *
Secs 90.7
1 Also have heterogeneous compound architecture (metacomputer) gotten by arbitrary combination of MIMD or SIMD, Sequential or Parallel machines.
2 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
3 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
