Paralleling of the three-dimensional model of the admixture transfer in the distributed memory systems using one-dimensional and two-dimensional domain decomposition

In the article the authors present paralleling of the computing algorithm of the solution of the system of the advective-diffusive-kinetic equations of the mathematical model of the transfer of the minor constituents of the admixture taking into consideration their chemical interaction in the atmosphere bottom layer. The paralleling is based on the one- or two-dimensional decomposition of the rated domain using the synchronous operations for the interprocessor data transfer. The efficiency of the worked out parallel algorithm using various decomposition modes and transput organization were tested using the cluster of the Tomsk State University «СКИФ Cyberia» (SKIF).
