ABSTRACT Shen, Y.; Qi, D.; Zhou, N., and Wang, X., 2018. Workflow task scheduling algorithm for marine environment data processing under multi-core computing environment. In: Liu, Z.L. and Mi, C. (eds.), Advances in Sustainable Port and Ocean Engineering. Journal of Coastal Research, Special Issue No. 83, pp. 646–650. Coconut Creek (Florida), ISSN 0749-0208. When the current workflow task scheduling algorithm is used for marine environment data processing, there is a large amount of calculation, poor load balancing, and lower data transmission efficiency. Therefore, in this paper, a workflow task scheduling algorithm based on multi-task replication strategy is proposed for the marine environment data processing under multi-core computing environment. Firstly, based on the directed acyclic graph, the workflow task structure of marine environment data processing can be described, to establish workflow model, and build a multi-level task replication model the DAG diagram of workflow. The model is combined wi...
