WIDESim: A toolkit for simulating resource management techniques of scientific Workflows In Distributed Environments with graph topology
share
This paper presents a toolkit for simulating resource management of scientific workflows in distributed environments with graph topology called WIDESim. WIDESim can work with all three different structures of scientific workflows: single, multiple workflows, and workflow ensembles. Also, unlike most existing network simulators, there is no constraint on the topology of the distributed environment. We have analyzed the performance of WIDESim in comparison to standard simulators and workflow management tools. The comparison indicates that WIDESim's performance is close to existing standard simulators besides its improvements
