| Popis: | The paper covers the investigation of hydrodynamics processes in shallow water taking into account the salt and temperature transport on supercomputer. Proposed model is based on the equations of motion (Navier-Stokes), the continuity equation for the case of variable density, as well as the equations of transport of salts and heat. The complex geometry of the coastline and bottom surface of natural reservoirs involves solving a number of problems related to the selection of parameters and the construction of the computational grid used for the numerical implementation of a discrete analogue of the mathematical model of hydrodynamic processes. Improving the accuracy of calculations, fulfilling the conditions of convergence and stability of the numerical solution of the problem involves crushing the step of the computational grid, which leads to the need to use supercomputer computing systems to obtain calculation results for a given period of time. The developed numerical methods and algorithms formed the basis of a software package tested on a supercomputer cluster using OpenMP and MPI technologies. Algorithms are being developed that adapt individual elements of the software package for the NVIDIA CUDA architecture and cloud computing. |
