Abstract


The grid the inlet software is integrated display a Web application on grid resources and services . Grid portal software shields the internal details of complex grid resources to users through a familiar user interface , consistent with the mode of operation convenient and efficient access mechanism using a grid system and access to grid services , so as to solve the grid system resource use complex issues . Grid Monitoring provides important data and resources for other grid middleware grid system is found by the grid system performance tuning and error basis , is an important support for the successful completion of the assurance task , and the task of monitoring the grid monitoring indispensable part . Task scheduling relationship grid efficient use of resources , quickly complete the task of key components . In this paper, the use of the analysis grid mode , designed and implemented a grid portal software - WebGrid . Research and Implementation of WebGrid expand around the grid monitoring and task scheduling , task runtime monitoring concept study existing grid monitoring mechanism and task scheduling mechanism for research is relatively weak in the task of monitoring the status quo , the combination has some distributed technology , developed autonomous grid monitoring system ; task allocation algorithm based on genetic algorithm , the algorithm uses resources - indirect encoding task , hierarchical relationship through the the DAG diagram for subtasks , and subtasks in accordance with levels of depth Sort solve the illegal population . Globus task on a single resource scheduling policy . WebGrid user security management the MyProxy mechanism , to resolve the inconsistencies GSI security mechanisms and web security agreement , prompting a smooth combination between . WebGrid using Web-based navigation , the integration of Web functionality and parallel computing technology available to the user graphical interface and convenient , easy-to-use operating environment .
