Implementation of System Software of Multiprocessor Computing Systems for Solving Applied Tasks
(«Пороги», Дніпро, 2021) Shvachych, Gennady Grygorovych; Moroz, D.
ENG: The paper proposes a concept for making a multiprocessor computing system designed to solve aviation industry's problems, which would have peak real efficiency and productivity. In addition, this system should be characterized by increased reliability and high energy efficiency. Blocks of the proposed system were implemented with the help of mass production computing facilities. The FAWN technology has further developed. The research considers the problems of use and adjustment of system software of the multiprocessor computing system. For the designed MCS, the OS Linux was selected. It is now considered standard for computing cluster systems. In addition, the section discusses the use of communication tools (interactions) among the nodes of the multiprocessor computing system. It is shown that the most widespread in our time parallel programming technology with partitioned memory is MPI technology. The results of intermediate and final computations are transmitted to the TCA via a managed Infiniband switch. In this case, the control and transfer of the corresponding data from the slave-nodes is carried out by HCA network adapters.
Main Problems and Principles of Implementation of Distributed Data Registry Technology
(Scientific Publishing Center “Sci-conf.com.ua”, 2022) Shvachych, Gennady Grygorovych; Kholod, Olena Grygorivna; Chernetskyi, Sergiy Oleksandrovich
ENG: This paper shows that information and communication technologies, particularly the digital economy, reveal a huge range of opportunities. It was noted that its strengths, the reducing costs, increasing the level of security, and transparency of transactions drew the attention of various economic sectors. In this regard, for a clear and definite understanding of the problems under consideration, the author's definition of the digital economy, digital technologies in the economy, and "end-to-end" digital technologies in the economy were introduced. The paper highlights the most intensively developing main components of the digital economy: distributed ledger technologies (blockchain) and real option technologies. Research has shown that blockchain technology is one of the main directions for the digital economy development. As a decentralized data registry, the paper shows that blockchain technology is the most discussed and relevant topic in the digital economy. Its strengths are analyzed, such as cost reduction, high security, and transaction transparency applicable to various economic sectors. The main mechanisms of contradictions, arrangement, and implementation of blockchain technology are detailed with the author's approach to eliminating the identified contradictions.
Object-Oriented Model of Constructing of the Distributed Databases
(ТОВ «ЮРИДИЧНА КОМПАНІЯ «ЮРСЕРВІС», 2022) Shvachych, Gennady Grygorovych; Moroz, B.; Hulina, I.
ENG: The proposed object-oriented system model provides a solution to a complex of planning and reporting problems in fuzzy sets based on symmetric pairs of cryptographic keys. In the proposed system, the object identifiers (cryptographic keys) describing structure of the high educational establishments and the learning process are automatically generated on the basis of complete (standardized) names of structural divisions, specialties, disciplines, etc. Unlike classic relational databases, the object-oriented model allows solving effectively problems of such automatic transactions, such as inheritance of the past period plan parameters in the new period plan, the inheritance of the previously described structures. In addition, it allows removal and adding to the work plan of new periods, as well as new structures designed to provide interactive automatic postings of students during the entire period of their studying, etc.
