THE TECHNIQUE OF CONSTRUCTING OF OPERATIONAL GRAPH MODEL OF THE PROGRAM

Thepurpose, ways of presentingand technique of constructing of operational graph model of the program (OGMP) is considered. Main stages of the operational graph model constructing are pointed and problems in their implementation are noted. A software tool for support of OGMP constructing is described. The tool was developed and used in the laboratory workshop of the MOEVM department for the calculation of program performance characteristics. The features of the implementation of this software tool main components are noted such as the module of the arrangement of control points (CT), which ensures the introduction of the CT function calls into the text of the program and the creation of the program control graph (PCG) and theprogram loading module forming the required OGMP in the form of a graph with loaded arcs. In conclusion, we propose a procedure for verifying the adequacy of the established OGMP, confirming the correspondence of its behavior to the work of the program under study
