METHODICAL MAINTENANCE
Distributed computing environments like Grid are characterized by heterogeneity, low cohesion and dynamic structure of computing nodes. This is why the task of resource scheduling in such environments is complex. Different approaches to job scheduling in grid exist. Some of them use economic principles. Economic approaches to scheduling have shown their efficiency. One of such approaches is cyclic scheduling scheme which is considered in this paper.
Cyclic scheduling scheme takes into account the preferences of computing environment users by means of an optimization criterion, which is included in the resource request. Besides, the scheme works cyclically by scheduling a certain job batch at each scheduling step. This is why there is a preliminary scheduling step which is job batch generation.
The purpose of this study was to estimate the infl uence of job batch structure by the user criterion on the degree of its satisfaction. In other words we had to find the best way to form the batch with relation to the user optimization criterion. For example if it is more efficient to form the batch with jobs with the same criterion value or with different criterion values. Also we wanted to find the combination of criterion values which would give the most efficient scheduling results.
To achieve this purpose an experiment in a simulation environment was conducted. The experiment consisted of scheduling of job batches with different values of the user criterion, other parameters of the resource request and the characteristics of the computing environment being the same. Three job batch generation strategies were considered. In the first strategy the batch consisted of jobs with the same criterion value. In the second strategy the batch consisted of jobs with all the considered criteria equally likely. The third strategy was similar to the second one, but only two certain criteria were considered. The third strategy was considered in order to find the most favorable combinations of criteria couples.
The experiment showed that the second approach showed the best scheduling results. This may be explained by a smaller degree of competition for similar resources in the case of different criteria combination. Experiment results for criteria couples depend on the considered couple. The best scheduling results for this strategy were shown by criteria couples with job runtime and cost minimization criteria and job completion and cost minimization criteria.
The results of the study are a part of course “Computing Systems” at the department of Computing engineering at National Research University “Moscow Power Engineering Institute”. Further studies will be dedicated to the search of optimal correlation between user criteria in one batch.
The article deals with the problems that arise when a human is involved into a complexly training systems and the environment. A theoretical analysis of the infl uence of consciousness on the training mechanisms within the framework of post non-classical conceptions of human psyche functioning was conceived. We argue that consciousness is not intended to refl ect the objective reality and acquire knowledge, and solves the problem of the construction of the subjective world, which is the sum of compromises between the subject and the dynamic environments of his experience. In contrast, consciousness selects and harmonizes the information useful for human life.
The role of consciousness in training is largely contradictory and confusing. It is also the source of the new information. The information is distorted in order to create a world view, which tends to objectively contradictive to the outside observer and consistent for refl ective being. We stressed the important role of human’s multimodal sensory experience in the process of interaction between conscious and unconscious forms of knowledge creation and processing. We consider the qualitative difference between physical reality and the model presented in the subjective world. We postulated the existence in the mind of a human dynamic virtual model. According to this model, the natural world is delimited by person and opposed to it being a source of events that make up the content of his life. The border which was built in the consciousness divides constructed reality into the inner and outer worlds. These worlds have different significance for the subject, defining the nature of its activities.
We analyzed models the structure of reality and reality as a world’s refl ection offered by Karl Popper, K. K. Kolin, R. Redfield, G. Roth. The attention was paid to the neurobiological model of subjective reality by V. Sergin, which proposed a hypothesis of automatic identification postulating a secondary to human sensory categories. These processes occur cyclically, and their frequency determines the speed of subjective time. The authors of this article propose a mechanism of generating a subject environment (the world of reality) according to which the environment is perceived by man. It is organized element of subjective reality constructed by the body in the process of analyzing the essential relationship of the body and physical reality.
It is presented in the form of coordination with other autopoietic systems that allow for the integration of the body and the subject in a niche of individual existence. It is a complex structural evolutionary self-organizing system, resulting from the interaction and coordination of autopoietic systems of the body. Subjective reality is the result of a reduction in the physical reality organization of the human psyche. We show the infl uence of the mind on the mechanisms of human integration with artificial learning environments. It is concluded that in order to improve the effectiveness of complex training ergonomics systems must take into account the properties of conscious regulation of the subject, its dependence on the context. To protect against the destructive mechanisms of action of consciousness training we advise to restrict the user’s intervention in critical modes of operation created a complex training system.
EDUCATIONAL ENVIRONMENT
At the present stage, broad information and communication technologies (ICT) usage in educational practices is one of the leading trends of global education system development. This trend has led to the instructional interaction models transformation. Scientists have developed the theory of distributed cognition (Salomon, G., Hutchins, E.), and distributed education and training (Fiore, S. M., Salas, E., Oblinger, D. G., Barone, C. A., Hawkins, B. L.). Educational process is based on two separated in time and space sub-processes of learning and teaching which are aimed at the organization of fl exible interactions between learners, teachers and educational content located in different non-centralized places.
The purpose of this design research is to fi nd a solution for the problem of formalizing distributed learning process design and realization that is signifi cant in instructional design. The solution to this problem should take into account specifi cs of distributed interactions between team members, which becomes collective subject of distributed cognition in distributed learning process. This makes it necessary to design roles and functions of the individual team members performing distributed educational activities. Personal educational objectives should be determined by decomposition of team objectives into functional roles of its members with considering personal and learning needs and interests of students.
Theoretical and empirical methods used in the study: theoretical analysis of philosophical, psychological, and pedagogical literature on the issue, analysis of international standards in the e-learning domain; exploration on practical usage of distributed learning in academic and corporate sectors; generalization, abstraction, cognitive modelling, ontology engineering methods.
Result of the research is methodology for design and implementation of distributed learning process based on the competency approach. Methodology proposed by authors determines specifi cs of educational objectives, learning content and distributed learning lifecycle design, approaches to implementing learning scenarios, as well as the functions and roles of students and teachers in a distributed interaction. Main advantage of the author’s methodology is that it allows to use various paradigms (behaviorism, cognitivism, constructivism) in instructional design. It is applicable to all levels of distributed learning: traditional face-to-face learning with ICT support, blended learning, distance learning in virtual learning environments.
Conclusion. Methodology presented by the authors has been tested in the professional teachers training programs for IT-teachers to be at the Novokuznetsk Institute (Branch) of Kemerovo State University in the curriculum of disciplines ‘Educational process management informatization’, ‘Innovative methods and technologies for e-learning’ and ‘Distance learning organization’.
NEW TECHNOLOGIES
The article presents the approaches to the creation of cloud information system for automation of business processes related to the preparation and publication of periodic scientific and educational publications (publishing). The aim of the research is the development of concepts, models, patterns, architecture of such a system, the choice of software implementation. The urgency of development based on the results of a study of existing and used in practice technologies for creating electronic versions of scientific journals and other types of scientific and educational resources. It is expected that the use of cloud-based systems will reduce the time and cost of publishing houses, as well as improve the quality of published material (for example, through the use of their interactive and multimedia elements, add comments and assessment opportunities articles and so forth.).
Description is given on an example of cloud Redactor.Online system developed by small innovative enterprises of Petrozavodsk State University «Internet-business-system». As a means of implementation chosen freelydistributed products, such as PostgreSQL, PHP, Yii Framework.
Logically, the cloud structure of the system is a set of components, based on common data sources and interacting with each other. The main components of the system are the basic (general) part of promo-site system, editorial offices of periodicals created in the system, media sites, mobile applications editions, complex control system as a whole.
The central element of the system architecture is the editorial offices. It provides a set of features related to the preparation for release and publication of the magazine, including the management of the lifecycle of the article (step preparation of the article the author, its review, proofreading, typesetting, translation, publication, and export to external citation indexes). Available functionality of this component is determined by the role assigned to the user - the editorial staff or author. Allocate such basic roles (offices), as a author office, reviewer office, corrector office, translator office, designer office, the editor’s office. A single user can have multiple roles, and perform various functions related to the preparation of articles for publication (eg, translate, and adjust the paper). You can also specify the settings in the publication, and the role of the steps which are required and which are not needed.
Using Redactor.Online system built on the basis described in this paper approaches will significantly reduce the time and costs for the implementation of business processes related to organizational activities of publication and for potential users of the system, including educational and research institutions, engaged in release electronic journals. system interfaces and subsystems allow the Internet fast enough to create the appropriate publication site and configure its design, content, access parameters, modes of operation, in accordance with the requirements of the creator.
RUSSIAN AND FOREIGN EXPERIENCE
The article describes the work on support and development of information infrastructure NRU «MPEI». Information infrastructure have different approaches to the defi nition. The authors defi ne the information infrastructure as a set of basic information services, computing, storage and data transmission systems that provide user access to information resources. New conditions dictate new approaches to building the education system in general and the educational process in each educational institution. NRU «MPEI» working to create a modern information infrastructure, including automated control systems, information resources and services, modular systems disciplines. This article describes the requirements for a modern information infrastructure of the NRU «MPEI», that provides students and teachers with the necessary services. Information infrastructure includes a set of software and hardware to ensure interaction between the participants of the educational process. All services and NRU «MPEI» system included in the unifi ed information educational environment (UIEE). Architecture UIEE NRU «MPEI» is displayed in the article. UIEE NRU «MPEI» is deployed on the basis of information network NRU «MPEI» and enables a comprehensive optimization of university management in various areas. Information and Computing Center supporting information and computer network NRU «MPEI», bought more than 4800 licenses in 43 different license versions of the software manufacturers. The server segment information network NRU «MPEI» contains a complex infrastructure and application servers for processing and storing information.
The segment there are 20 high-performance server and storage system capacity of over 30 TB. In the server segment deployed complex systems to meet the needs in the various fi elds of activity NRU «MPEI», and the educational system to support the economic , scientifi c and human complex. Currently, ICC also pays great attention to the development of educational and innovation center, the initiative is aimed at improving the qualifi cations of teaching staff and training of students. For example, SAP technology are in fact the standard of corporate information systems for large enterprises, it is about 49.9% of the worldmarket. Therefore, every year, since 2008, the SAP Training Center - MPEI produces 40-45 graduates to work in energy companies and other industries.
The preparation of an engineer is a challenge and a decision it is not possible without the widespread introduction of information and communication technologies in all spheres of activity of the university: teaching, research , management of the various spheres of activity . According to the authors , the use of modern information infrastructure for Engineering Education will allow to solve this problem effectively.
The article is devoted to the unified information environment of National Research University “Moscow Power Engineering Institute” (MPEI), and its most important component – the HR information system. The article describes the architecture of the unified information space of MPEI. The main objective of the development of the HR information system – to provide access to users, including other information systems, to actual information about employees of MPEI.
HR information system are based on many years of operating experience of the previous system and the like, are available on the market today, taking into account the decisions of personnel. The earlier HR information system was developed in 1995–1997 and used until mid-2015. In the process of its using it has accumulated a large number of «patches» and requests for revision that was stopped by limitations in the platform and solutions architecture. Comparative analysis of 1C and SAP products showed that the cost of implementation, configuration and maintenance of these products is higher than developing new solutions. Package of Microsoft technology software was chosen as a platform. These technologies have proven themselves in the development of similar projects, and vendor solutions for a long time support all key processes of information systems. Important is the presence of the selected software Microsoft FSTEC certificates (Federal Service for Technical and Export Control), which support the use of these products for storing and processing information in accordance with the laws of the Russian Federation. The MPEI has already implemented a number of systems on the Microsoft platform – postgraduate register, an Internet portal, etc. The use of technology of one supplier facilitates the integration processes and products into a unified information environment. The article details the technical and hardware specifications of the HR information system. The result of the work on the HR information system is stably functioning, supporting all business processes of the subject area and have successfully integrated within other software system. In addition to the «standard» option for storing information about employees («core» fields of the form, documents, various types of information on professional development, incentives, penalties, planned and actual vacations, etc..). HR information system has its own mechanism for the generation of orders and changes as a result of their approval. The subsystem orders included several modules: route editor, layout editor, orders editor, rights editor. Route Editor allows you to describe the route of the order to determine the movement and «point» statement, which if it enters the data into HR information system have to be updated on the basis of the text of the order. Template Editor is used to describe the future of the text of the order, the parameters that must be requested from the members of their processing before entering the text and action in approving an order. The orders editor works on the basis of a template, and provides opportunities for the formation of the order of the text and its harmonization in the course of the route and approval. The rights editor is used to distinguish the rights when dealing with orders subsystem. This article contains more detailed information about the frames of program of HR information system.
In conclusion contained the positive experience of exploitation of the system and the introduction of a general trend to develop and support another IT solutions.
The social aspect (the restructuring of thinking, way of life and activity, quality of life, education) is determined by the deficiency of fundamental scientific information on trends, issues, necessary conditions and possibilities of using foreign experience in managing the social consequences of scientific and technological development (progress) at the present stage of Russian modernization.
In this context, the changes, introduced by the scientific and technical progress (STP), which invade all aspects of human life, changing labor incentives, education and representation of human happiness, become an important object of study.
Purpose of the study. The study of foreign experience of social consequences of scientific and technological development (progress) at the present stage to assess the possibility of fragmented or integrated use of the new knowledge in the formation of long-term strategies for the development of science and technology, taking into account the social needs of society.
R & D tasks. To effectively address the problems of modernization and restructuring of Russia it is necessary to explore and identify patterns and trends in the development of scientific and technological progress and social aspects of thinking changes, lifestyle and human activities for their subsequent use in the measurement and control of the social aspects of human life. To this should be investigated:
1. Peculiarities of scientific and technological development in the next stage of the «long wave» of progress, which leads to the need for programming the development of the social aspect of the measure and the regulation of the quality of human life.
2. Positive and negative social consequences of the development of scientific and technical progress.
3. The impact of new challenges, factors and conditions, caused by the development of science and technology.
4. Proposals for the analysis of the linkages and the risks of introduction of science and technology in everyday life.
5. The role of education in preventing the consequences of scientific and technological progress
