| Abstract | Climate simulations are very computational time consuming tasks which are usually solved in parallel systems. However, to reduce the time needed for the simulations, a set of parameters must be optimally selected. This paper presents a methodology to select such parameters for a particular simulation code (the MM5 mesoescalar model). When the code is installed in a computational system its behaviour when executing the code is characterized by a set of parameters. The values obtained are included in a model of the execution time of the code, and the simulation is carried out at running time with the running configuration with which the lowest theoretical time is obtained. An important reduction in the execution time is achieved. In the experiments the reduction is between 25% and 40%. The methodology proposed could be applied to other problems in which the code to be optimized is considered as a black box. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
