References and Source Material

Much of the explanatory material in this book was taken from the following canons:

  • Lenoski, Daniel and Weber, Wolf-Dietrich. Scalable Shared-Memory Multiprocessing San Francisco: Morgan Kauffman, 1995.

  • Hennessy, John and Patterson David. Computer Architecture: A Quantitative Approach San Mateo, California: Morgan Kauffman, 1990

  • Schimmel, Curt. Unix Systems for Modern Architectures Menlo Park, California: Addison Wesley, 1994

James Laudon's System Specification and Cache Coherence Protocol Specification provided a wealth of information. Both are internal Silicon Graphics® documents.

Typographical Conventions

Italic

  • is used for emphasis

  • is used for bits, fields, and registers important from a software perspective (for instance, address bits used by software, programmable registers, etc.)

Bold Text

  • represents a term that is being defined

  • is used for bits and fields which are important from a hardware perspective (for instance signals on the backplane, or register bits which are not programmable but accessible only to hardware)
