Моделирование формирования УНС в плазмес использованием параллельных вычислений

Abstract

The article deals with the method of solving a mathematical model of the forma-tion of cluster groups of carbon, which form carbon nanostructures (CNS) in low-temperature plasma during thermal sublimation of graphite. Traditionally, mathematical models of this type are solved numerically, using supercomputers or Grid-technologies. This approach has a high cost and is not always available for engineering calculations. An alternative option is to use the resources of modern personal computers (PC). Technology application parallelization on CPU and GPU allows us to perform General-purpose computations on the graphics processors of the graphics card of the PC. The presented algorithm based on the method of large particles (MCС) allows to obtain a numerical solution of the model with the use of Nvidia CUDA technology on a PC. Approaches to parallelization of CPU and GPU calculations are proposed and the execution time of various algorithms for calculation of the electromagnetic field parameters and search for collisions of particles in plasma is analyzed. The quantitative characteristics of the influence of the main parameters of the process on the number of carbon cluster groups in the plasma of interelectrode space, which are the basis of the formation of the CNS, are obtained
