A Workflow-based Computational Resource Broker with Information Monitoring in Grids

Chao-tung Yang, Cheng-fang Lin, Sung-yi Chen
2006 2006 Fifth International Conference on Grid and Cooperative Computing (GCC'06)  
Also, we constructed a grid platform using Globus Toolkit that integrates the distributed resources of five universities in Taichung, Taiwan, where the resource broker is developed.  ...  As a result, the proposed broker provides secure and updated information about available resources and serves as a link to the diverse systems available in the Grid.  ...  MPICH-G2 is a grid-enabled implementation of the MPI v1.1 standard. That is, it uses services from the Globus Toolkit (e.g., job startup, security).  ...

Meta-Broker for Future Generation Grids: A New Approach for a High-Level Interoperable Resource Management [chapter]

Attila Kertész, Péter Kacsuk
2008 Grid Middleware and Services  
One very important aspect of utilizing multiple Grids within one complex scientific workflow is to interact with multiple and potentially different grid brokers supported by different Grids.  ...  As grid technology matures the number of production grids dynamically increases. The management and the optimal utilization of these grid resources cannot be handled by the users themselves.  ...  This service can act as a bridge among the separated islands of the current production Grids and user groups, therefore it enables more beneficial resource utilization and collaboration.  ...
