Foil 10 What is Parallel Architecture?

From Methodology of Computational Science CPS615 Computational Science -- Spring Semester 2000. by Geoffrey C. Fox
1 A parallel computer is any old collection of processing elements that cooperate to solve large problems fast
  • from a pile of PC's to a shared memory multiprocessor
2 Some broad issues:
  • Resource Allocation:
    • how large a collection?
    • how powerful are the elements?
    • how much memory?
  • Data access, Communication and Synchronization
    • how do the elements cooperate and communicate?
    • how are data transmitted between processors?
    • what are the abstractions and primitives for cooperation?
  • Performance and Scalability
    • how does it all translate into performance?
    • how does it scale?
