Документ Multiagent methods of management of distributed computing in hybrid clusters(Національний технічний університет "Харківський політехнічний інститут", 2022) Kolumbet, Vadim; Svynchuk, OlhaModern information technologies include the use of server systems, virtualization technologies, communication tools for distributed computing and development of software and hardware solutions of data processing and storage centers, the most effective of such complexes for managing heterogeneous computing resources are hybrid GRID-distributed computing infrastructure combines resources of different types with collective access to these resources for and sharing shared resources. The article considers a multi-agent system that provides integration of the computational management approach for a cluster Grid system of computational type, the nodes of which have a complex hybrid structure. The hybrid cluster includes computing modules that support different parallel programming technologies and differ in their computational characteristics. The novelty and practical significance of the methods and tools presented in the article are asignificant increase in the functionality of the Grid cluster computing management system for the distribution and division of Grid resources at different levels of tasks, the ability to embed intelligent computing management tools in problem-oriented applications. The use of multi-agent systems for task planning in Grid systems willsolve two main problems - scalability and adaptability. The methods and techniques used today do not sufficiently provide solutions to these complex problems. Thus, the scientific task of improving the effectiveness of methodsand tools for managing problem-oriented distributed computing in a cluster Grid system, integrated with traditional meta-planners and local resource managers of Grid nodes, corresponding to trends in the concept of scalability and adaptability.Документ Практичні аспекти організації розподілених обчислень в науковій та навчальній діяльності університету(Луцький національний технічний університет, 2018) Круглов, Олександр АнатолійовичДокумент Создание композитных приложений на основе распределённых сервисов(Харківський національний університет Повітряних Сил ім. Івана Кожедуба, 2016) Бульба, Сергей Сергеевич; Кучук, Георгий Анатольевич; Лисица, Дмитрий АлександровичПроанализированы как позитивные, так и негативные стороны различных вариантов создания композитного приложения (КП) на основе распределённых сервисов. Показано преимущество сервисов распределенных облачных технологий для создания корпоративных систем обработки информации с использованием композитных приложений, основанных на принципе потока заданий. Разработано формальное описание отдельного КП, необходимое для дальнейшего построения абстрактного потока заданий. Обоснована необходимость разработки новой технологии описания композитных приложений, основанной на использовании потока заданий, которая может соединить все преимущества существующих методов построения композитных приложений в соответствующей предметной области.Документ The analysis of expert system for adapting decisions for determining the type of radio response sources(НТУ "ХПІ", 2018) Gatsenko, Serhiy; Buchinsky, YuriyIn this article, the authors of research described the sources of radio radiation and explained the complexity of identifying sources of radioelectronic radiation under a priori uncertainty. Authors of the article state, that the source of radio-electron radiation can be identified by a set of parameters of its signal. It is established that the informational nature of the signal source of radio emission for the devices of radio monitoring depends on how reliable this signal is detected and how accurately (precisely) its parameters are determined, which are useful days of radio monitoring of the message or value. Because signal tracking always takes place against a background of different kinds of interference, the fact of detecting a signal, as well as errors in measuring signal parameters and selecting messages are always random. The problem of determining the type of signal, and therefore the source, which it emits, is partially solved by the preliminary analysis of the ether on the hearing conducted by the operators of radiomonitoring. This makes it possible not to distract from non-informative signals belonging to sources of radio-electronic radiation that are not showing interest to radio monitoring, to shorten the search time for sources of radio-electronic radiation and to minimize the cost of depreciation of equipment. The disadvantage of this method is the necessity to have a sufficient number of trained operators and to constantly increase their training. Was given that the preparation of one operator to a professional level can last 6-12 months, it is very difficult to provide data requirements. Therefore, in the given article it is suggested to analyze the parameters of sources of radio-electronic radiation on a set of parameters of sources signals of radio-electron radiation with the help of expert decision support system concerning determination of sources parameters of radio-electronic radiation. In the article, the authors proposed an expert system for determining the parameters of sources of radio-electronic radiation using a database management system. Unlike machine programs that use procedural analysis, expert systems solve problems in a narrow subject area (specific field of expertise) based on deductive considerations. Such systems are often able to find solutions that are unstructured and poorly defined. They cope with the lack of structuring by involving heuristics, that is, the rules described in accordance with the experience of using the equipment, which may be useful in those situations where the lack of necessary knowledge or time eliminates the possibility of complete analysis.
