Foil 33 Functional Parallelism in Algorithms

From Master Foilset for CPS615 Introduction -- Material from Culler and Koelbel Computational Science for Simulations -- Fall Semester 1998. by Geoffrey C. Fox, Nancy McCracken
Functional parallelism exploits the parallelism between the parts of many systems.
  • Many pieces to work on ? many independent operations
  • Example: Coarse grain Aeroelasticity (aircraft design)
    • CFD(fluids) and CSM(structures) and others (acoustics, electromagnetics etc.) can be evaluated in parallel
Analysis:
  • Parallelism limited in size -- tens not millions
  • Synchronization probably good as parallelism natural from problem and usual way of writing software
  • Web exploits functional parallelism NOT data parallelism
