Description
Conclusions and Future Work
NMMC3D was ported to the SEE-GRID-SCI infrastructure as a workflow based parameter study. As the next step we will extend the gridified NMMC3D program with an application specific portlet. The portlet will provide extremely simplified user interface to perform mantel simulations on the grid, making earth scientist capable of using EGEE through the NMMC3D application service. Our work demonstrates a model to publish grid applications as easy to use services.
Detailed analysis
The outer part of the Earth consists of moving, rotating and interacting plates. Numerical calculations suggests that plates are formed by sheet-like elongated downwellings (subduction zones) and narrow, cylindrical upwellings (mantle plumes, at the hotspots). The main goals of our research are the quantitative study of the structure and surface manifestation of mantle plumes and to make systematic investigation of the parameters influencing the characteristics of mantle convection in 3D. Using the parameter study features of P-GRADE Portal environment we have created a grid application that enables end users to run NMMC3D on gLite middleware. Significant speedup in numerical modeling of Mantle Convection was achieved by the grid-enabled version. End users can configure and manage the execution process from a user friendly grid portal environment. By the parameter study services of P-GRADE Portal the application has been ported to gLite quickly and effectively.

Impact
Mantle convection is the driving force of the plate tectonics, a principal theory of geosciences. As scientific impact, the modeling of mantels will help us to understand better the dynamics of the Earth. As social impact, we can name the theoretical research, direct impact mostly in the research community of geosciences. The application initiated collaboration between the Seismological Observatory from Geodetic and Geophysical Research Institute, Department of Geophysics from Eötvös Loránd University, Institute of Geography and Earth Sciences in Hungary and other institutes from the Southern Eastern European region. The presentation will introduce the technical details of the application porting process, providing a reusable porting pattern for attendees of the User Forum.
