Аннотация:DVM-system is designed for the development of parallel programs of scientific and technical calculations in C-DVMH and Fortran-DVMH lan-guages. These languages use a single parallel programming model (DVMH model) and are extensions of the standard C and Fortran languages with paral-lelism specifications, written in the form of directives to the compiler. The DVMH model makes it possible to create efficient parallel programs for hetero-geneous computing clusters.The article presents new features of DVM system for working with checkpoints, which are based on the use of parallel I/O.
