First Considerations about Modelling the Ocean General Circulation on MIMD Machines by Domain Decomtive-equation finitedifference ocean general circulation model..We present our point of view about Domain Decomposition Methods, architectures of machines and their programming models..After we present our choices to parallelize the explicit part (data management, subdomain topology…) and the implic

Application of Fifth-Order Compact Upwind Differencing to Moisture Transport Equation in AGCM,tencil. Several 1-D and 2-D advection tests were performed including the test on the sphere with the flow over the poles. The used time stepping were implicit third-order Adams scheme and explicit fourth-order low-storage Runge-Kutta method. This scheme was also implemented in atmospheric general ci

A Parallel Algorithm for Simulation of Long Range Transport of Air Pollution,uld be able to benefit substantially from effective parallel algorithms. In this paper we describe a continuous domain decomposition algorithm for advection-diffusion equations. The algorithm is applied to an air pollution model, involving advection in the horizontal directions and advection-diffusi

Multidisciplinary Mathematical Model for Earthquake Prediction Studies,plinary) earthquake precursor are considered. Our aim is the construction of a variant of the multidisciplinary mathematical model describing the formation, propagation and interaction of geophysical fields of different physical nature and changes of their anomalies in the earthquake prone zones for

Basic functional representation of programs for automatic differentiation in the , system,r bundles. We deduce from this formalism the rules to apply to produce automatically the tangent linear code and the adjoint code by manipulating the initial program. We present the . system and its application to two meteorological projects: . and arps. We also describe how we build and analyse a p

Translation Tools for High Performance Computing,d size and complexity. One of the primary stumbling blocks to this promise has been the lack of tools to automatically translate application codes to MPP form. In this paper we show how applications codes written in a subset of Fortran 77 called Fortran-P can be translated to achieve good performanc

Efficiency of a Number of Processors in Integrating a Global Weather Model,fferent resolutions. It is found that at the present level of parallelisation of the code, the maximum speedup and efficiency achieved for 48 processors are 41 and 85% respectively. Further parallelisation of the model is being attempted to decrease the elapse time for its long term integration on t
