Architectural Conclusions, Continued

What is best machine design?

• Latency hiding Tera is most customized, expensive in many dimensions

  • Wave of the future?
  • Overkill on supporting parallelism?

• Beowulf is most primitive, cheapest

  • Underperforms -- more engineering would help
  • Cheap enough to waste
  • Other applications

• Cray T3D & T3E

  • Global addressing + 1 sided comm is fast/handy
  • Low latency network design effective
