List scheduling algorithm
Web7 mrt. 2013 · Abstract: Efficient application scheduling algorithms are important for obtaining high performance in heterogeneous computing systems. In this paper, we present a novel list-based scheduling algorithm called Predict Earliest Finish Time (PEFT) for … 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 ...

Web10 mrt. 2024 · Four list-based algorithms (HEFT, CPOP, PEFT, EXT_HEFT) have been considered for performance analysis by considering randomly generated synthetic DAGs as input and compared in terms of the Schedule Length Ratio (SLR), speedup, efficiency, and running time of algorithms. 5 View 3 excerpts, cites background WebIn paper [ 8 ], Graham defines an algorithm called List Scheduling ( ls ). The algorithm receives jobs one by one. Each job is assigned in turn to a machine which has a minimal current load. Ties are broken arbitrarily. The main result is the following. Theorem 1 ls has a competitive ratio of { 2-\frac 1m } . Proof.

Web1,1,2 on 2 machines. If both task of duration 1 are scheduled rst, the makespan will be 3 instead of 2. We can improve this bound using a speci c list-scheduling algorithm. LPT, which stands for Longest Processing Time rst, considers a list of tasks sorted by non-increasing processing time, and schedule them on the available resources. Theorem 2. WebThe remainder of this paper is structured as follows. In Sect. 2 we summarize the relevant existing literature. Then in Sect. 3 we explicitly define the simulation model we use to study the static task scheduling problem. We describe HEFT in detail in Sect. 4, including also benchmarking results with our simulation model and a minor modification to the …
