List scheduling algorithm
WebEfficient scheduling algorithms have been a leading research topic for heterogeneous computing systems. Although duplication-based scheduling algorithms can significantly reduce the total completion time, they are generally accompanied by an exorbitant time complexity. In this paper, we propose a new task duplication-based heuristic scheduling … Web9 sep. 2016 · This paper presents a novel list-based scheduling algorithm called Improved Predict Earliest Finish Time for static task scheduling in a heterogeneous computing environment.

Webtion delays. For example, consider Graham’s list scheduling algorithm, which greedily processes jobs on m machines as soon as they become available. One can revisit the analysis of Graham [Gra66] and show that there exists a chain Q of dependent jobs such that the makespan achieved by list scheduling is bounded by 1 m X j∈J pj + X j∈Q pj ... WebAlgorithm 1: List-Scheduling algorithm Instance: we are given mmachines, m(m 1) jobs with processing times 1, and a single job with processing time m. Let LS schedule the 1 jobs first, and the mjob last. The makespan of this schedule is clearly 2m 1. OPT schedules the 1 jobs on m 1 machines, and the mjob on the remaining one. The …
