Annotation DVMH model (DVM for Heterogeneous systems) was introduced at Keldysh Institute of Applied Mathematics, Russian Academy of Sciences in 2011. High level programming languages which are standard FORTRAN and C languages, extended with directives to map on a parallel machine and implemented as special comments (or pragmas) were developed for new heterogeneous and hybrid supercomputer systems. The problems and methods of mapping of the loops with dependencies on graphics processors are described, and performance of Fortran DVMH versions of NAS NPB tests is demonstrated.
