Looking for an Evolution of Grid Scheduling: Meta-Brokering [chapter]

Ivan Rodero, Francesc Guim, Julita Corbalan, L. L. Fong, Y. G. Liu, S. M. Sadjadi
2008 Grid Middleware and Services  
In this paper we discuss the requirements to achieve a more uniform access to the Grids through a new approach to global brokering with new scheduling techniques.  ...  This situation causes two main problems: the user uniform access to the Grid is lost, and the scheduling decisions are taken separately while they should be done in coordination.  ...  Acknowledgements This research has been supported in part by the Spanish Ministry of Science and Technology under contract TIN2004-07739-C02-01, the EU project HPC-Europa under contract 506079, the FP6  ...
