摘要
Abstract
Scientific workflow on distributed computing environment has huge data transfer and storage, Aiming at this problem, on the environment of an executing machine which have limited storage resource, this paper disassembles the tasks of workflow into data jobs and computing jobs. The model of new workflow which include data jobs and computing jobs is proposed. It inserts data clear job when those data are no longer needed and transfer jobs when data need to transfer from one executing node to others, the method of creating the new workflow is provided. Schedule algorithm for scientific workflow based on the consider of available storage is proposed. Experimental results indicate that the schedule algorithm consumes less response time and raises the efficiency.关键词
