“…The experiment, though using a dedicated network, showed significantly reduced transfer time and so would be expected to have a significant impact when using a busy shared Internet connection with low bandwidth. In the near future, the new RNP (Brazilian National Research and Education Network -NREN) network infrastructure will provide Dynamic Circuit Provisioning for Brazilian institutions, with the main purpose of delivering bandwidth on demand for applications with high demand for quality of service (QoS) [25]. In this context, this work is particularly important, since RNP connects the meteorological centers in Brazil and this new approach will permit the creation of a computational grid on demand to support weather forecast production by guaranteeing bandwidth for meteorological information data transfers.…”

“…The non-dedicated RNP ("Rede Nacional de Pesquisa e Ensino") communication network provides the means to the transfer of meteorological information from INPE/CPTEC to local centers. RNP is Brazil's NREN (National Research and Education Network) and provides advanced network services to the higher education and research community [25].…”

This paper introduces a grid-based approach to reduce the time to deliver local meteorological forecast information. The computation of local meteorological forecasts relies on the execution of both regional and local scale Numerical Weather Prediction models. Typically, such models require extensive computation on large compute clusters. Moreover, the models are commonly executed sequentially, since local models rely on the output of a regional model. The approach introduced in this paper, modifies the computational dependencies in order to compute the models more in parallel while ensuring that computational results are appropriately synchronized. We evaluate the method in a high performance computing grid using the Brazilian Regional Atmospheric Modelling System (BRAMS). The experimental results show a reduction of up to 71 % in the time to deliver local meteorological information with this approach. The approach is sufficiently general that it can be useful with other large distributed applications.

Many important societal activities are global in scope, and as these activities continually expand world-wide, they are increasingly based on a foundation of advanced communication services and underlying innovative network architecture, technology, and core infrastructure. To continue progress in these areas, research activities cannot be limited to campus labs and small local testbeds or even to national testbeds. Researchers must be able to explore concepts at scaleto conduct experiments on world-wide testbeds that approximate the attributes of the real world. Today, it is possible to take advantage of several macro information technology trends, especially virtualization and capabilities for programming technology resources at a highly granulated level, to design, implement and operate network research environments at a global scale. GENI is developing such an environment, as are research communities in a number of other countries. Recently, these communities have not only been investigating techniques for federating these research environments across multiple domains, but they have also been demonstration prototypes of such federations. This chapter provides an overview of key topics and experimental activities related to GENI international networking and to related projects throughout the world.
