DVM-system is designed for the development of parallel programs of scientific and technical calculations in C-DVMH and Fortran-DVMH languages. These languages use a single parallel programming model (DVMH model) and are extensions of the standard C and Fortran languages with parallelism specifications, written in the form of directives to the compiler. 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 describes the method of debugging parallel programs in DVM-system, as well as new features of DVM-debugger.
