Modern software is used in computers with several processing elements, therefore, it should be developed using the technology of parallel programming. Currently, there are several technologies for development of parallel programs. Special attention should be paid to the means that allow “to make parallel” developed consecutive program immediately by means of adding special instructions to its initial code; according to which the compilation environment will form parallel variant of the code and performed file. OpenMP technology belongs to the means of such type. Ada programming language has its own means for the development of parallel software, which allow developing a parallel program of any complexity. However, using the built-in parallelization of Ada language could complicate the process of software development and make the program text impossible for understanding and analysis. The means similar to OpenMp technology provide more convenience while paralleling algorithms. The opportunity to introduce OpenMp technology directives to Ada programming language is shown in this paper; the ways for replacement of directives by parallel language constructions are analyzed; the general consequence of actions is represented while transforming from consequent Ada program with OpenMp directives to parallel Ada program. The opportunities of implementing some OpenMP directives by means of Ada language are considered in the work. The variant of parallel directive and corresponding pattern are presented. The article includes the examples of program code.References
