This article discusses modern server monitoring systems. The subject area under review concerns the control and management of high-performance computing systems (HPC). These systems are used in various branches of science and industry for modeling systems and their behavior in various conditions. The speed of the simulation depends on the applied technical solutions as part of the computing complex. These include the type of internal network, the number and types of computing nodes. For computing nodes, consider such parameters as the architecture and model of the processor, the amount of RAM. The features associated with the implementation of specific mathematical models that affect the speed of calculations are not considered in this article. The paper analyzes the existing market solutions and the main concepts used for the management and monitoring systems of such complexes. The systems under consideration are evaluated from an economic and technical point of view. For the available systems, a full-scale study of the cluster management and status monitoring capabilities is conducted. The set of parameters recorded by the monitoring system is taken based on the general architecture of the HPC and the approach to the administration of server systems. The practical part describes the experience of designing and implementing a promising management system. In the system being created, the main focus is on creating a management system. The justification for the need for a separate software product is given in the text of the article. Implementation issues in a specific program code and system environment are omitted, as they depend on the specific execution of the system. The task of creating your own monitoring system is considered insignificant, provided that existing solutions are available.

In this paper, we present the Web-based CALL environment (or WALL) which is currently being experimented with at the University of Paris 13 in the Computer Science Department of the Institut Universitaire de Technologie. Our environment is being developed to teach computer science (CS) English to CS French-speaking students, and will be extended to other languages for specific purposes such as, for example, English or French for banking, law, economics or medicine, where on-line resources are available.English, and more precisely CS English is, for our students, a necessary tool, and not an object of study. The learning activities must therefore stimulate the students' interest and reflection about language phenomena. Our pedagogical objective, relying on research acquisition (Wokusch 1997) consists in linking various texts together with other documents, such as different types of dictionaries or other types of texts, so that knowledge can be acquired using various appropriate contexts.Language teachers are not supposed to be experts in fields such as computer sciences or economics. We aim at helping them to make use of the authentic documents that are related to the subject area in which they teach English. As shown in Foucou and Kübler (1998) the wide range of resources available on the Web can be processed to obtain corpora, i.e. teaching material. Our Web-based environment therefore provides teachers with a series of tools which enable them to access information about the selected specialist subject, select appropriate specialised texts, produce various types of learning activities and evaluate students' progress.Commonly used textbooks Tor specialised English offer a wide range of learning activities, but they are based on documents that very quickly become obsolete, and that are sometimes widely modified. Moreover, they are not adaptable to the various levels of language of the students. From the students' point of view, working on obsolete texts that are either too easy or too difficult can quickly become demotivating, not to say boring.In the next section, we present the general architecture of the teaching/learning environment; the method of accessing and using it, for teachers as well as for students, is then described. The following section deals with the actual production of exercises and their limits. We conclude and present some possible research directions.

Currently, to increase the efficiency of industrial production, high-performance and expensive technological equipment is increasingly used, in which the weakest link, from the point of view of efficiency and reliability, is the components and parts of heavily loaded tribo – couplings operating both at significantly different temperatures (conditionally under lighter conditions, the temperature difference can be 100-120 degrees) and climatic conditions (high humidity, the presence of abrasives and other chemical elements in the atmosphere). As the results of the analysis of the frequency of failures of friction units and, accordingly, the cost of their restoration reach 9-20 percent of the cost of all equipment, without taking into account significant losses of income (profit) of the enterprise from downtime. The solution of this problem is based on the study of the wear rate of friction units by the wear products accumulated in working oils, cooling lubricants, and greases. A digital equipment monitoring system (DSMT) has been developed and implemented, which includes dynamic recording of the number of wear products and oil temperature by original modern recording devices, followed by the technology of their processing and use. The system also includes methods for finding the necessary information in large data sets useful and necessary in theoretical and practical terms with a similar technique controlled by a digital monitoring system. The advantages of SMT are the ability to predict the reliability of the equipment; reduce production risks and significantly reduce inefficient costs.

Statistics show that energy is one of the highest operating costs in a manufacturing enterprise. So, improving energy efficiency can lead to a significant increase in profits and reduce the impact of the enterprise on the environment. To increase the performance of energy efficiency activities, it is necessary to implement an energy management system. One of the components of this system is energy monitoring, which, in turn, is based on the periodic collection and analysis of data to assess the state of the monitoring objects in terms of energy efficiency. In this paper, the role and place of energy monitoring in the energy management system of an industrial enterprise are noted. The paper proposes the concept of creating energy monitoring system in industrial companies, which is based on the combination of a monitoring system based on specific energy consumption, and usage of group energy characteristics of production facilities. Implementing such energy monitoring systems will allow to conduct operational control of energy efficiency of production facilities by creating individual systems for monitoring energy efficiency, as well as successfully carry out such monitoring at the enterprise and its subdivisions over longer periods of time using specific energy consumption indicators. It also provides general guidelines for conducting energy monitoring. These guidelines were formed based on the results of studying various methods and scientific publications in the field of energy monitoring, as well as on the basis of practical experience in the development and implementation of energy management systems. Particular attention is paid to the issues of processing and analysis of information about the objects of energy monitoring of industrial enterprises. The practical application of the concept of creating energy monitoring systems envisages gradual improvement of the existing monitoring system based on the specific energy consumption, which will be further completely replaced with individual energy efficiency monitoring systems.

<p>The paper deals with the problem of ranking alternatives to geodynamic monitoring systems in the case of uncertainty of their implementation time. The problem is characterized by the fact that the choice of alternatives and the effect of it depends on the quality properties of the applied organizational and technical solutions, taking into account the time of implementation. The ordering of alternatives is proposed taking into account the uncertainty of the implementation time factors. Ranking is realized by comparing the trees of functional characteristics of alternatives taking into account the compliance of their characteristics with time-varying requirements. The scope of the proposed method is the choice of configurations of geodynamic monitoring systems with significant differences in the implementation time of alternatives.</p>

Advanced computations on embedded devices are nowadays a must in any application field. Often, to cope with such a need, embedded systems designers leverage on complex heterogeneous reconfigurable platforms that offer high performance, thanks to the possibility of specializing/customizing some computing elements on board, and are usually flexible enough to be optimized at runtime. In this context, monitoring the system has gained increasing interest. Ideally, monitoring systems should be non-intrusive, serve several purposes, and provide aggregated information about the behavior of the different system components. However, current literature is not close to such ideality: For example, existing monitoring systems lack in being applicable to modern heterogeneous platforms. This work presents a hardware monitoring system that is intended to be minimally invasive on system performance and resources, composable, and capable of providing to the user homogeneous observability and transparent access to the different components of a heterogeneous computing platform, so system metrics can be easily computed from the aggregation of the collected information. Building on a previous work, this article is primarily focused on the extension of an existing hardware monitoring system to cover also specialized coprocessing units, and the assessment is done on a Xilinx FPGA-based System on Programmable Chip. Different explorations are presented to explain the level of customizability of the proposed hardware monitoring system, the tradeoffs available to the user, and the benefits with respect to standard de facto monitoring support made available by the targeted FPGA vendor.

The purpose of the study: to investigate and evaluate the design features, technical level and quality of the control and monitoring system SCSO-25 produced by SPE Monad Kherson installed on the grain drill SZ-3 "Astra-3". Research methods: analytical and experimental, field, operational-technological and agro-technical research. Research results. For research of the control system operation the SCSO-25 seeding control and monitoring system (Monada SPF LLC) was selected and installed on the SZ-3 Astra-3 grain mounted seed drill. According to the results of agro-technical assessment, it is established that the drill sows the specified number of seeds, determined by the control system of SCSO-25. According to the test results, it is established that the grain seeder SZ-3"Astra-3" with the control system SCSO-25 constantly performs the technological process provided by the technical conditions. At a speed of 11.4 km/h. deviation of the actual seeding rate from the established one was 1.3%. At the same time, the uneven sowing between individual sowing machines and the instability of the total sowing were obtained within the TC and amounted to 1.62% and 0.73%, respectively (according to the TC not more than 3.0 and 2.8%). And wrapping the seeds to the desired depth made it possible to obtain the relative field germination of barley seeds at 92.8%. Conclusions. According to the test results, the control and management system SCSO-25 has a fairly high technical level and thanks to a wide range of functions and settings allows to stably control the parameters of the seeder SZ-3 "Astra-3" and meets the technical requirements. In addition, the control system creates a technological track for intensive technology of growing cereals in accordance with the specified parameters. The creation of a tramline allows saving the expensive seed from 4 to 8 %, which also has a positive effect on the formulation of the production cost. The use of the SZ-3 "Astra-3" with the control and management system SCSO-25 improves the working conditions of the operator, allows more efficient use of working time and saves expensive seed, which in turn helps to increase profitability.
