Usage of Fortran DVMH language for solving hydrodynamics problems on hybrid computing systems

In the 2011 year DVMH programming model for new heterogeneous and hybrid supercomputer systems (or DVM for Heterogeneous systems) was introduced in the Keldysh Institute for Applied Mathematics of RAS. The developed high-level programming languages were based on standard Fortran and C programming languages, but extended with the directives for mapping the program onto a parallel computer. The directives are represented as special comments (or pragmas). The paper includes analysis of the efficiency of the developed programs for solving the hydrodynamics problems «Cavity» and «Container». The calculation results are gained by using several thousand CPU cores and gained by using more than 1200 GPU accelerators are presented.
