An Integration of Global and Enterprise Grid Computing: Gridbus Broker and Xgrid Perspective

Several middleware for grid computing have been proposed aiming at providing means to access resources in a uniform and secure way, hiding the idiosyncrasies of heterogeneous resources. In this work we present the Enterprise Grids from the Xgrid perspective and the Global Grids perspective from Gridbus. We also present the integration of Enterprise and Global Grids by proposing the integration of Gridbus Broker with diverse enterprise grid middleware technologies including Xgrid, PBS, Condor and SGE. The implementation of Xgrid Actuator that enables the use of Xgrid services via Gridbus Broker is presented as a representative implementation. The sample performance results demonstrate the usefulness of this integration effort.
