Abstract

Scheduling workflow applications in grid environments is a great challenge, because it is an NP-complete problem Many heuristic methods have been presented in the literature and most of them deal with a single workflow application at a time In recent years, there are several heuristic methods proposed to deal with concurrent workflows or online workflows, but they do not work with workflows composed of data-parallel tasks In this paper, we present an online scheduling approach for multiple mixed-parallel workflows in grid environments The proposed approach was evaluated with a series of simulation experiments and the results show that the proposed approach delivers good performance and outperforms other methods under various workloads.
