Gustafson's law in parallel computing

Webity of a parallel platform, namely, speed-up, efficiency and asymptotic analysis. We continue with the presentation of two fundamental laws of scalability: Am-dahl’s and Gustafson’s laws. Our presentation considers the original arguments of the authors and reexamines their applicability in today’s machines and compu-tational problems. WebMar 23, 2024 · The relationships between the strong scaling and weak scaling applications and how much they could be accelerated by parallel computing are described by Amdahl’s law and Gustafson’s law, respectively. In this blog post, I would like to discuss Amdahl’s law and strong scaling, and Gustafson’s law and weak scaling.

2.1: The Amdahl

In computer architecture, Gustafson's law (or Gustafson–Barsis's law ) gives the speedup in the execution time of a task that theoretically gains from parallel computing, using a hypothetical run of the task on a single-core machine as the baseline. To put it another way, it is the theoretical "slowdown" of … See more Gustafson estimated the speedup $${\displaystyle S}$$ of a program gained by using parallel computing as follows: where • $${\displaystyle S}$$ is the theoretical speedup of the … See more Application in research Amdahl's law presupposes that the computing requirements will stay the same, given increased processing power.
