The issues of improving the reliability of the functioning of the computing process are in the focus of attention of many developers and researchers of computer systems. Based on an analysis of research in this area, we came to the conclusion that the theory of reliability of computing systems has not yet been adequately developed, and none of the available groups of methods provides a satisfactory solution to the problems of reliable functioning of the computing process under given restrictions on cost and efficiency. The article discusses the main software methods of diagnosis and control, highlights their significant shortcomings. The conclusion is drawn on the need to develop new methods of program control and diagnostics of the computation process. These methods should ensure reliable functioning of the computing process in the conditions of hardware failures, and allow recovering the computing process and data from the consequences of failures in an acceptable time for the diagnosed process. The definition of the computing process as a sequence of elementary acts on a change in the state of the environment is refined. A path has been outlined for choosing mathematical models of the computing process, the most suitable of which are schemes of programs and algorithms.
