Abstract
In paper was presented an attempt to implement Vortex In Cell (VIC) method on Graphics Processing Units (GPUs). The 3D VIC method was shortly described. To show correctness of the code the motion of a vortex ring was simulated. At rst the numerical calculation were done on the single processor (x86) architecture. Disadvantage of the single processor computation is time consumption. To manage this problem we switched to the parallel architecture. In our rst approach to the multicore architecture we tested algorithms for the solution of the algebraic system of equations that results form discretization of the Poisson equation. For parallel computations CUDA architecture was used. We used the Multigrid and the Full Multigrid methods. It permitted us to speed up the solution of algebraic system using the Full Multigrid method 10-times. Finally, the whole Vortex In Cell was implemented on the GPU. A 15-times speed-up was obtained.
