The Fundamental Laws of Parallelism

Chapter

Abstract

This chapter introduces the basic laws of parallelism that have influenced the research and practice of parallel computing during the past decades. We discuss Amdahl’s and Gustafson’s law as well as the equivalence of the two laws; we also analyze how Amdahl’s law can be applied to multi-core chips and what implications it can have on architecture and programming model research. Finally we present some of the more controversial rules and conjectures, such as the KILL rule and Gunther’s conjecture .
