The work is dedicated to the topic of parallelizing programs in especially difficult cases - when the used algorithm is purely sequential, there are no parallel alternatives to the algorithm used, and its execution time is unacceptably high. Various parallelization methods for software implementations of such algorithms and resulting computational load balancing are considered, allowing to obtain significant performance acceleration for application programs using purely sequential algorithms. The above methods are illustrated by the practice of their application to two algorithms used in a dynamic binary code analysis toolset. The main goal of this paper is to show that the use of a purely sequential algorithm in a software implementation does not necessarily imply inevitability of its sequential execution. The proposed methods of parallelizing implementations of such algorithms and balancing the resulting computational load can help to develop efficient parallel program that fully utilize the hardware capabilities of modern computing systems.
