Research and Implement of Grid Portal Based on Gridport

Grid portal is the entrance which users apply all kinds of grid services. In this paper, it provides architecture of gird portal based on gridport, and discusses the flow of job submission, deploys resource monitoring services, and designs resource allocation algorithm. Finally, it tests the variance ratio of RAM by resources monitoring services and the performance of resource allocation algorithm by GridSim based on 3D reconstruction application. The results show that architecture of gridport may support the execution of job submission, resources monitoring and resource allocation.
