摘要：Parallelization is a core strategic-planning consideration for all software makers, and the amount of performance benefit available from parallelizing a given application (or part of an application) is a key aspect of setting performance goals for the parallelization process. Theoretical discussions of performance potential are necessarily the starting point for understanding the critical issues involved, before moving to practical issues associated with a given project. Amdahl's Law and its modification by Gustafson's trend give us the basic means to understand what's possible for a given application, and tools and best practices give us the means to decide how to use that information in practice.
