    Basic directions of information technology in National Academy of Sciences of Azerbaijan
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 657-660

    Grid is a new type of computing infrastructure, is intensively developed in today world of information technologies. Grid provides global integration of information and computing resources. The essence Conception of GRID in Azerbaijan is to create a set of standardized services to provide a reliable, compatible, inexpensive and secure access to geographically distributed high-tech information and computing resources a separate computer, cluster and supercomputing centers, information storage, networks, scientific tools etc.

    Aspects of methodology of ensuring interoperability in the Gridenvironment and cloud computing
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 675-682

    The technique of ensuring of interoperability for Grid-systems and systems of cloud computing is provided. The technique is constructed on a basis of the uniform approach of ensuring interoperability for systems of the wide class offered by authors and recorded in the national Russian Federation standard.

    Keywords: interoperability, grid, grid-environment, cloud computing, clouds, methodology, standardization.

    Synthesis of the simulation and monitoring processes for the development of big data storage and processing facilities in physical experiments
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 691-698

    The paper presents a new grid and cloud services simulation system. This system is developed in LIT JINR, Dubna, and it is aimed at improving the efficiency of the grid-cloud systems development by using work quality indicators of some real system to design and predict its evolution. For these purpose, simulation program is combined with real monitoring system of the grid-cloud service through a special database. The paper provides an example of the program usage to simulate a sufficiently general cloud structure, which can be used for more common purposes.

    Keywords: grid computing, cloud computing, data storage, monitoring, optimization, simulation.

    Experience of puppet usage for managment of Tier-1 GRID cluster at NRC “Kurchatov Institute”
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 735-740

    This article is about the organization of the cluster management using puppet. It tells about: safety of usage, from the point of view of mass apply at a computing cluster wrong configuration (by reason of human factor); collaboration work and the creation of opportunities for each cluster administrator, regardless of others, writing and debugging your own scripts, before include them in the overall system of cluster managment; writing scripts, which allow to get as fully configured nodes, and updates the configuration of any system parts, without affecting the rest of the nodes components, regardless of the current state of the node of computing cluster.

    The article compares different methods of the creation of the hierarchy of puppet scenarios, describes problems associated with the use of “include” for the organization hierarchy, and tells about the transition to a system of sequential call classes through shell-script.

    Keywords: puppet, automation of configuration, joint cluster management, puppet use cases.
