- I doubt that other topics covered in these sections have changed much, but do check.
- Sections 1.3.3 and 1.3.4: Most changes here are probably related to performance metrics.
- Cite other models for measuring artifacts such as data-transfer time, overhead, occupancy, and communication cost.
- Focus on the models that are most useful in practice.
