An approach to the development of debuggers that use semantics of constructs of parallel programs

In the paper, a new approach to the development of interactive debuggers for parallel programs that use message-passing model is suggested. The basic idea of the approach is to design a debugger specific to a particular language or a parallel programming library and to use information about the semantics of constructs used in the parallel program for processing commands of the step-by-step execution and data representation. The development of the user interface and internal debugger structure, as well as their implementations in the debuggers for mpC programs and programs using the MPI library, are considered.
