Grid technologies and future proofing
Execution environment and Grid tools: The key to the development and execution environment is to ensure that the Grid is useable directly from the environment where the climate modelers are performing their work, and thus to augment and enhance their tools of choice, rather than force them to abandon them. In GENIE this strategy has proved successful with the integration of Grid computing into environments such as Matlab and Python, along with augmentation using web based access mechanisms. The special challenges in this project to exploit data assimilation methods and uncertainty analysis will require new e-Science technology developments to couple together large scale data and compute intensive calculations built from a common unified ESM within the integrated framework. Furthermore, there is a need to provide tools to facilitate the exploitation of data produced from large scale studies in further model development. Our strategy of ensuring that such developments are driven directly by the needs of the science has enabled new science to be delivered, and at the same time allowed us to contribute to and enhance generic Open middleware stacks such as the GeodiseLAB toolkits for grid-computing, data handling and XML methods which are to be released by the Open Middleware Infrastructure Institute. We will continue to exploit and enhance Grid-enabled computing and data handling resources using toolkits such as Condor, Globus, and OMII.
New tools: The project will have close links to the Open Middleware Infrastructure Institute at University of Southampton to exploit their web services stack and this will further leverage other existing projects such as the National Grid Service and the NERC datagrid project.
Linkage to the NERC datagrid: Compatibility between the existing GENIE data system (based on GEODISE) and the NERC datagrid will be developed to establish a database system that can be maintained by the British Atmospheric Data Centre (BADC) beyond the lifetime of the project.
