The paper is devoted to the development of a methodology for evaluating the scalability of compute-intensive iterative algorithms used in simulating complex physical processes on supercomputer systems. The proposed methodology is based on the BSF (Bulk Synchronous Farm) parallel computation model, which makes it possible to predict the upper scalability bound of an iterative algorithm in early phases of its design. The BSF model assumes the representation of the algorithm in the form of operations on lists using high-order functions. Two classes of representations are considered: BSF-M (Map BSF) and BSF-MR (Map-Reduce BSF). The proposed methodology is described by the example of the solution of the system of linear equations by the Jacobi method. For the Jacobi method, two iterative algorithms are constructed: Jacobi-M based on the BSF-M representation and Jacobi-MR based on the BSF-MR representation. Analytical estimations of the speedup, parallel efficiency and upper scalability bound are constructed for these algorithms using the BSF cost metrics on multiprocessor computing systems with distributed memory. An information about the implementation of these algorithms in C++ language using the BSF program skeleton and MPI parallel programming library are given. The results of large-scale computational experiments performed on a cluster computing system are demonstrated. Based on the experimental results, an analysis of the adequacy of estimations obtained analytically by using the cost metrics of the BSF model is made.

“…The basis of the new paradigm in digital design and simulation of global competitive product of new generation is considered to be by and large in making smart digital twins. As the scientists interpret the term today, a digital twin is a hierarchic system of mathematical models, computation methods and programming services allowing for the synchronization in real time between the state of a real lasting process, or a system, and its virtual copy [1][2][3]. According to chief analytics officer Gartner -M. Halpern, "a digital twin is not just a 3D-model, but a virtual model of an 'object'.…”

The article shows the results of the research in the area of cross-sectoral network interaction of structures in the digital economy. The research sums up the analysis of the up-todate practices of digital twins management in Russia and worldwide and enlarges on the effects of digital twins employed in such economic sectors as automotive industry, healthcare, education, culture, trade, transport and agriculture. The emphasis is made on the big data becoming the major active of modern business. Moreover, they are the data connected within a certain network that may add to the value of a company. The eleven basic principles of cross-sectoral network interaction of structures in the digital economy have been elicited as such reflecting the concept of adding value to business: the principle of consistency; the principle of synergy; the principle of the electronic exchange quality in terms of data and documents exchange in the form of business operations between the structures from different sectors; the principle of automated control; the principle of digital design of management processes; the principle of horizontal and technological cooperation between the partners within the network; the principle of continuous training of staff in the area of digital innovations; the principle of SDM client oriented approach; the principle of procedure standardization; the principle of cross-cultural digital communications; the principle of socially responsible partnership. Conditioned by the rapidly developing digital communications, cross-sectoral cooperation is marked by the transition from the rigid hierarchical structures to the flexible horizontal network structures capable of swiftly adjusting the configuration of their links to the new designs of technologically advanced partnership.

Microservice architecture style has been gaining wide impetus in the software engineering industry. Researchers and practitioners have adopted the microservices concepts into several application domains such as the internet of things, cloud computing, service computing, and healthcare. Applications developed in alignment with the microservices principles require an underlying platform with management capabilities to coordinate the different microservice units and ensure that the application functionalities are delivered to the user. A multitude of approaches has been proposed for the various tasks in microservices-based systems. However, since the field is relatively young, there is a need to organize the different research works. In this study, we present a comprehensive review of the research approaches directed toward microservice architectures and propose a multilevel taxonomy to categorize the existing research. The study also discusses the different distributed computing paradigms employing microservices and identifies the open research challenges in the domain.
