MIMOZA code was used for computing Zababakhin sloyka (layer cake type) in 16 pairs of heavy and light layers with aspect ratios 0.1 and 0.2 respectively with outer radius 10{cm} and central domain radius 0.0652{cm}. The computations were carried out with/without regard to heat conduction. Parallelization is essential with domain size difference by the factor of 1000. As the basis for paralellization algorithm the authors used a scheme, in which different computational domains were computed on separate processor elements, the values obtained at the previous time step were taken as at the next step. To shorten processors downtime computational domains are rearranged at the end of each step and the order of their computation is changed according to statistics, obtained at the previous step.
