Iterative development of parallel programs in the ParJava environment

A technology of the iterative development of parallel programs and the corresponding development tools on the basis of the ParJava environment are considered. A benefit of the ParJava environment is that the the most part of the work can be done on a development computer using a model of the parallel program to be developed. This considerably reduces the the overheads in terms of time and resources used. The proposed technology is illustrated using the development of a parallel program for simulating intense atmospheric vortices as an example.
