CPE 315
Professor Stearns
Flynn's Multiprocessor Taxonomy

• SISD Computer
  
  One CPU - the kind we have studied all quarter

• MIMD Single Bus Computer
  Multiple CPUs share the same bus and have equal access to memory and I/O devices.
  A problem is restricted bus bandwidth and length.
  A more common term for a MIMD machine - Symmetric Multiprocessor (SMP)
  Here is an [incomplete and out-of-date] list of Commercial SMPs
  CPE 459 covers SMPs and parallel programming.
  

• MIMD Networked Computer
  Multiple CPUs connect via a network; each CPU has its own memory. There are a wide variety of network topologies used to make the connections.
  CPE 464/465 cover networks.
  

• SIMD Computer (commonly called a vector processor)
  Copies of a single program run on multiple CPUs; each CPU operates on different data sets.
