Abstract: Nowadays, the rapid growth in the computer performance is mainly achieved due to the use of hybrid architectures including the multi-core CPUs and graphics accelerators. However, such architectures cause serious difficulties in their efficient employment and make new demands to the software development. One of the most promising approaches to construct the efficient applications for such systems consists in the creation of computational algorithms with a simple logical structure. This approach has been used at the development of the cross-platform unified parallel program library for modeling such large-scale processes in the underground space as given by the contaminant infiltration into the soil, oil recovery problems and so on. The library is written in C++ using the MPI and CUDA technologies. It consists of calculation, communication as well as control modules and allows computations of 2D and 3D problems with double precision, which can be realized on both the GPU and the NUMA cluster multi-core CPUs, the access to different memory types is optimized. To verify the developed parallel programs, some test calculations in the infiltration and oil recovery problems have been performed on the hybrid supercomputer with 100 TFLOPS peak performance.
