parallel loop scheduling feedback-guided dynamic loop scheduling algorithms PARALLEL LOOPS SCHEME

In this paper we consider the Feedback-Guided Dynamic Loop Scheduling (FGDLS) method that was proposed by Bull [2]. The method uses a feedback-guided mechanism to schedule a parallel loop within a sequential outer loop. The execution times and the scheduling bounds at a outer iteration are used to find the scheduling bound of the next outer iteration. In this way FGDLS achieves an optimal load balance. Two algorithms have been proposed so far by Tabirca et al. [13], [14]. In this article we will review these two algorithms and will give a comparison between their performances.
