A BPEL-Based Grid Workflow Engine
Geng Jia-bin · Microcomputer Information · 2008
In order to run complex grid application automatically,the grid workflow technology is referred to.In this paper,we pre-sent BPEL FlowEngine—a BPEL-based grid workflow engine for executing grid workflow instances.Besides basic functions of a con-ventional BPEL-based workflow engine,BPEL FlowEngine has many features including hierarchical processing mechanism,multiple types of task scheduling,transaction processing,etc,which are of paramount importance to supporting workflow instances using BPEL language.We conduct comprehensive experiments to evaluate the performance of BPEL FlowEngine,and the results of comparing with GWES are presented as well.At last,we will discuss a real application of BPEL FlowEngine in the field of bioinformatics.
