The article describes various options for speeding up calculations on computer systems. These features are closely related to the architecture of these complexes. The objective of this paper is to provide necessary information when selecting the capability for the speeding process of solving the computation problem. The main features implemented using the following models are described: programming in systems with shared memory, programming in systems with distributed memory, and programming on graphics accelerators (video cards). The basic concept, principles, advantages, and disadvantages of each of the considered programming models are described. All standards for writing programs described in the article can be used both on Linux and Windows operating systems. The required libraries are available and compatible with the C/C++ programming language. The article concludes with recommendations on the use of a particular technology, depending on the type of task to be solved.

In this paper, SC-expressions are developed, based on automata theory, for specifying synchronization constraints in parallel object-oriented languages. The predecessor of SC-expressions, the synchronization expressions, was introduced in the ParC parallel programming language in the early nineties [19]. However, ParC is not an object-oriented language and also a number of basic features of synchronization expressions are inadequate for object-oriented languages. SC-expressions are developed for object-oriented environment. They are different from synchronization expressions in basic ideas and assumptions. Here we describe the basic ideas of SC-expressions and their applications in object-oriented languages. We also study the problem of inheritance of the SC-expressions.
