摘要

讨论了与大规模并行系统性能分析有关的问题。关注的重点是软件结构的平均并行度，它被提出作为并行软件的单参数表征。有人认为，并行软件或并行硬件的单参数表征很少能深入了解并行系统的软件和硬件组件之间的复杂相互作用。特别是，当模型忽略通信延迟的影响时，基于简单并行模型的加速界限就会被打破。

On single parameter characterization of parallelism

Issues pertinent to performance analysis of massively parallel systems are discussed. Attention is focused on the average parallelism of a software structure, which has been proposed as a single-parameter characterization of parallel software. It is argued that single-parameter characterization of parallel software or of parallel hardware rarely provides insight into the complex interactions among the software and hardware components of a parallel system. In particular, bounds for the speedup based on simple models of parallelism are violated when a model ignores the effects of communication delays.<>
