The paper discusses the implementation of alternating direction implicit parallel algorithm with CUDA technology to solve the problems of multiphase filtration of a multicomponent fluid in porous media. To solve the tridiagonal equations systems of alternating direction implicit method, cyclic and parallel cyclic reduction methods were used. The results of the study showed that the implementation of cyclic and parallel cyclic reduction algorithms on modern GPUs is much more efficient than on CPUs.

This article considered the numerical simulation of multicomponent multiphase flow in porous media. The resulting system of nonlinear equations linearized by the Newton-Raphson method and solved with the iterative Generalized minimal residual method (GMRES) algorithm. To achieve better convergence, we used the ILU(0) preconditioner to the GMRES algorithm. As a result, we used a completely implicit scheme called the Newton-ILU0-GMRES algorithm to solve the problem of interest. Based on the obtained sequential algorithm, we implemented a parallel algorithm using Message Passing Interface (MPI) technology. Additionally, we made comparisons between the parallel program of the presented algorithm and the parallel program using the ready-made Portable Extensible Toolkit for Scientific Computation (PETSc) library. We developed an MPI parallel algorithm and tested it on the MVS-10P supercomputer of the Interdepartmental Supercomputer Center of the Russian Academy of Sciences.
