Foil 59 Overview of Computer Architecture Issues

From Second set of lectures on CPS615 Parallel Computing Overview CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox *
Many issues both between architectures and internal to each architecture
Situation confused as need to understand
  • "theoretical" arguments e.g. fat-tree v. torus
  • technology trade-offs now e.g. optical v. copper links
  • technology as a function of time
is a particular implementation done right
  • in basic hardware
  • as a system with software
All that perhaps is important is what either user or high level software (compiler/message passing system) sees.
