Using the Cuda Technology to Speed up Computations in Problems of Chemical Kinetics

Abstract

The paper focuses on the problem of chemical kinetics, calculation of variations in the concentration of substances in the reactions over time, and creation of a mass kinetic solver to solve the problem using modern parallelization technologies. A mathematical model of variation in the concentration of substances in a system with a one-dimensional approximation and the possibility of accelerating the calculations using the CUDA technology is described. The calculation performed on NVIDIA graphic processor shows that an increase in the number of reactions much reduces the computing time as compared with the computing time on the central processors.
