DVM-system is designed for the development of parallel programs of scientific and technical calculations in the C-DVMH and Fortran-DVMH languages. These languages use a single DVMH-model of parallel programming model and are an extension of the standard C and Fortran languages with parallelism specifications in the form of compiler directives. The DVMH model makes it possible to create efficient parallel programs for heterogeneous computing clusters, in the nodes of which accelerators, graphic processors or Intel Xeon Phi coprocessors can be used as computing devices along with universal multi-core processors. The article presents new features of DVM-system that have been developed recently.

Аннотация. DVM-система предназначена для разработки параллельных программ научно-технических расчетов на языках C-DVMH и Fortran-DVMH. Эти языки используют единую модель параллельного программирования (DVMH-модель) и являются расширением стандартных языков Си и Фортран спецификациями параллелизма, оформленными в виде директив компилятору. DVMH-модель позволяет создавать эффективные параллельные программы для гетерогенных вычислительных кластеров, в узлах которых в качестве вычислительных устройств наряду с универсальными многоядерными процессорами могут использоваться ускорители (графические процессоры или сопроцессоры Intel Xeon Phi). В статье описывается методика отладки параллельных программ в DVM-системе, а также новые возможности DVMотладчика.
