Grid Workflow Based on Performance Evaluation

As the complexity of Grid applications increase, it becomes more important and urgent to provide grid workflow to construct and manage the applications. The grid workflow based on dynamic scheduling and performance evaluation is presented in this paper according to the standards of GCC and WFMC, which consists of user portal, resource management component, grid services management, performance management, grid workflow engine featured by dynamic scheduling. Then the prototype implemented on the Globus is introduced. Finally the experiment of genome sequencing based on shotgun algorithm is analyzed and the result is promising.
