Abstract

A general look at Amdahl’s law, which expresses the parallel processing advantage of a job with serial and parallel components. Variants of Amdahl’s law such as Gustafson’s law are discussed. The design of different multicore architectures is examined. A CPU/GPU example is considered. Delay and energy objective functions are presented. Finally, the role of Amdahl’s law in the context of local versus cloud processing tradeoffs is studied.
