In modern conditions, integrated automation of management is a promising and economically profitable direction of its development, and the intellectualization of management is becoming increasingly important. The construction of an integrated ship control system with a single control, carried out from an integrated central control post -the navigator's automated workplace in the ship's wheelhouse is a major urgent problem. To solve this problem, it is proposed to use a model of a distributed architecture system based on multi-agent technologies, the principle of which is based on the decomposition of the general task into a number of local tasks assigned to the agents of the system, the distribution of these tasks between agents, the planning of collective behavior of agents, coordination of agent interaction based on cooperation, reconfiguration, communication and conflict resolution.A number of problems solved by an integrated ship control system is identified in the paper and the implementation of multi-agent technology using the processes of a ship's motion control system is considered as an example. The structure of the knowledge base of a multi-agent ship motion control system is presented. A knowledge base management system the key elements or the main agents of which are the coordinator of software agents, the ontology manager, and the communicator of software agents, is presented. The general scheme of the organization of interaction of agent platforms in the ship movement management is presented. The principles on the basis of which a multi-agent system for controlling the ship movement should be created are formulated. It is noted that it is advisable to use a model developed based on the requirements of the Federation of Intelligent Physical Agents, the standard that governs the development of multi-agent systems, and also defines the logical model of the agent platform and a set of services as the base model of the class of intelligent agent. It is proposed that further research will be directed to the formation of many ontologies that make up the knowledge base of the integrated ship control system, the construction of a relevant knowledge base management system that implements effective interaction of the main agents, as well as to the development of agent platforms that provide solutions to the ship control tasks.

Recent achievements in high-performance computing significantly narrow the performance gap between single and multi-node computing, and open up opportunities for systems with remote shared memory. The combination of in-memory storage, remote direct memory access and remote calls requires rethinking how data organized, protected and queried in distributed systems. Reviewed models let us implement new interpretations of distributed algorithms allowing us to validate different approaches to avoid race conditions, decrease resource acquisition or synchronization time. In this paper, we describe the data model for mixed memory access with analysis of optimized data structures. We also provide the result of experiments, which contain a performance comparison of data structures, operating with different approaches, evaluate the limitations of these models, and show that the model does not always meet expectations. The purpose of this paper to assist developers in designing data structures that will help to achieve architectural benefits or improve the design of existing distributed system.
