Аннотация:The experience of using Cuda Unified Memory technology to develop Multi-GPU
applications is described. The paper deals with the method of transferring computations on the
MGDS-GPU model two-dimensional problem described by the equations of single-layer
shallow water with variable density over an uneven bottom. To solve the problem was applied
balance - characteristic scheme "CABARET". The minimum steps necessary to go from
computing on the GPU to computing on the MULTI-GPU are given. The computational
efficiency is investigated depending on the size of the grid.
