Foil 23 Back from the Analogy to Parallel Computers!

From Master Set of Foils for 1997 Session of CPS615 Basic Simulation Track for Computational Science CPS615 -- Fall Semester 97. by Geoffrey C. Fox


1 Now we go through a set of semi-realistic examples of parallel computing and show they use various forms of data parallelism
2 Seismic Wave Simulation: Regular mesh of grid points
3 Cosmology (Universe) Simulation: Irregular collection of stars or galaxies
4 Computer Chess: "Data" is now parts of a game tree with major complication of pruning algorithms
  • "Deep Blue" uses this global parallelism combined with optimal locally parallel evaluation of "score" of a position using special hardware
5 Defending the Nation: Tracking multiple missiles achieves parallelism from set of missiles
6 Finite Element (NASTRAN) structures problem: Irregular collection of nodal (grid) points clustered near a crack
