Reconfiguration Mechanisms for Virtual Organization Using Remote Deployment of Grid Services

Grid computing is becoming more and more attractive for coordinating large-scale heterogeneous resource sharing and problem solving. Although Globus toolkit version 4 which is developed based on WSRF can successfully deal with the heterogeneity of resources and the diversity of applications, the current grid environments based on Globus toolkit version 4 have several limitations regarding dynamic reconfiguration of virtual organization (VO) and remote hot deployment of grid services. This paper proposes WIVO (Web-based user Interface for Virtual Organization), the web-based user interface using web service. Using WIVO, user requested sub-VO can easily be configured on top of grid environment based on Globus toolkit version 4, and grid services can also be deployed remotely for better utilization of resources and applications. It is expected that the VO reconfiguration function as well as the remote grid service deployment function provided in WIVO can improve resource and application utilization.
