Foil 64 Application Trends

From CPS615-Introduction-Course,Driving Technology and HPCC Current Status and Futures CPS615 Basic Simulation Track for Computational Science -- Fall Semester 98. by Geoffrey C. Fox, (Some Culler, Koelbel material)
1 Demand for cycles fuels advances in hardware, and vice-versa
  • Cycle drives exponential increase in microprocessor performance (this is largely from low-end)
  • Drives parallel architecture harder: most demanding applications (this is high end driver)
2 Range of performance demands
  • Need range of system performance with progressively increasing cost
  • Platform pyramid
3 Goal of applications in using parallel machines: Speedup
  • Speedup (p processors) =
4 For a fixed problem size (input data set), performance = 1/time
  • Speedup fixed problem (p processors) =
