**5.1.2 Overall achievements**

The regional climate model version 4.1.1 was ported and tested on both Indian and European infrastructure and the feasibility and performance of executing the code on both HPC and grid infrastructure has been tested. It has been observed that the performance of the code on different platforms is comparable considering the CPU cores. The performance has been measured in terms of execution speed and the time taken to complete one execution.

Data management issues has been solved by means of the openDAP approach that proved to be efficient and feasible. This marks a considerable result that allow to exploit in a similar manner all the available computational resources without the need to move back and forth terabyte of data.

Finally Different simulations has been performed on the South Asia CORDEX domain to find out the best suited configuration of parameters and tune the model to be able to get the best possible results for the Indian sub-continent. The tuning is being done by performing various experiments using different set of parameters each simulation, for instance, using

e-Infrastructures represent a critical mean to provide access to important computing resources and specialized software to worldwide seismological community. In fact, e-science removes some of the infrastructural barriers that prevent collaborative work at the international level. Accordingly, the proposed scientific and computational tools and networking will permit a widespread application of the advanced methodologies for seismic hazard assessment, particularly useful for urban planning and risk mitigation actions in developing countries, and, in turn, will allow for a faster development and verification of

The use of the mentioned seismological methodologies can be optimized by the use of modern computational infrastructures, based on GRID computing paradigms. Advanced computational facilities, in fact, may enable scientists to compute a wide set of synthetic seismograms, dealing efficiently with variety and complexity of the potential earthquake sources, and the implementation of parametric studies to characterize the related

The application of the NDSHA approach to the territory of India already started in the framework of long-term bilateral cooperation projects Italy-India, involving ICTP/Sand group and CSIR C-MMACS (Bangalore). In that framework, a neo-deterministic hazard map have been produced for India, and specific studies have been performed to estimate the ground motion amplifications along selected profiles in the cities of Delhi and Kolkata. The collaboration has been recently extended to the ISR, Institute of Seismological Research

Preliminary studies have been devoted to expose seismologists and seismic engineers to modern e-infrastructures (which includes both HPC and Grid environments) so that the potential provided by this infrastructure for seismic hazard assessment research can be assessed and exploited. These activities aim to enable the computational seismology user community to the use of modern e-infrastructure and acquire the core innovations emerging in this framework, for example the development of an European and worldwide einfrastructure for advanced applications in seismic hazard assessment driven by European Union projects such as EU-IndiaGRID2. The major goals of this new collaboration are to:




Activities carried out so far have been dedicated to a general introduction to the e-Infrastructures for Grid and HPC and to the preliminary assessment of their use in seismological research, with special emphasis on methods for advanced definition of ground shaking scenarios based on physical modelling of seismic waves generation and propagation processes. Researchers gained some practice on the use of the e-infrastructure for neo-deterministic seismic hazard assessment at different scales and level of detail, working actively on Italian data and testing the specialized seismological software running

different convective precipitation schemes on land and ocean, modifying the values of the parameters in the regcm.in file and changing the landuse pattern. Scientific results of Indian Summer Monsoon using RegCM4.1 compared with those of Global Climate models such as GPCP and CRU are under study and will published soon.
