PBJIM: Plugin-based Job Interoperation Mechanism for Heterogeneous Grid Systems

With the development of grid technology, grid gains more popularity that ever and a variety of grid middlewares come into being. However, most of grid middlewares are developed by their own, and it´s not easy to intemperate these grid platforms. Existing grid interoperability projects mainly resorts to case-by-case mechanism, which is simple but of poor scalability. Job management is the core and the most complex components of grid system. To realize the interoperability of heterogeneous grids, the interoperation of heterogeneous job managements must be addressed. In the paper, a plugin based job interoperation mechanism for heterogeneous grid systems, called PBJIM, is proposed, which is based on the idea of virtualization and plug-in mechanisms. There are two well-established grid systems in China, ChinaGrid and China National Grid, and they are built with two different grid middlewares, CGSP and VEGA. Via PBJIM, the interoperation of job management of these two grid systems is achieved.
