摘要

研究了有向无环图(DAG)任务的响应时间界限。最近,人们提出了使用多条路径来绑定DAG任务的响应时间的想法,而不是在以前的结果中使用单个最长路径,并导致了所谓的多路径绑定。多路径边界可以大大降低响应时间界限,显著提高DAG任务的可调度性。本文导出了一个新的多路径界,并提出了计算该界的最优算法。我们进一步系统地分析了现有的三种多径界和提出的多径界的支配性和可持续性。我们的边界在理论上占主导地位,在经验上优于所有现有的多路径边界。而且,所提出的界是唯一被证明是自持续的多径界。

Multipath Bound for DAG Tasks
This article studies the response time bound of a directed acyclic graph (DAG) task. Recently, the idea of using multiple paths to bound the response time of a DAG task, instead of using a single longest path in previous results, was proposed and led to the so-called multipath bound. Multipath bounds can greatly reduce the response time bound and significantly improve the schedulability of DAG tasks. This article derives a new multipath bound and proposes an optimal algorithm to compute this bound. We further present a systematic analysis on the dominance and the sustainability of three existing multipath bounds and the proposed multipath bound. Our bound theoretically dominates and empirically outperforms all existing multipath bounds. What is more, the proposed bound is the only multipath bound that is proved to be self-sustainable.

期刊介绍: The purpose of this Transactions is to publish papers of interest to individuals in the area of computer-aided design of integrated circuits and systems composed of analog, digital, mixed-signal, optical, or microwave components. The aids include methods, models, algorithms, and man-machine interfaces for system-level, physical and logical design including: planning, synthesis, partitioning, modeling, simulation, layout, verification, testing, hardware-software co-design and documentation of integrated circuit and system designs of all complexities. Design tools and techniques for evaluating and designing integrated circuits and systems for metrics such as performance, power, reliability, testability, and security are a focus.
