    Computational task tracking complex in the scientific project informational support system
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 615-620

    This work describes the idea of the system of informational support for the scientific projects and the development of computational task tracking complex. Due to large requirements for computational experiments the problem of presentation of the information about HPC tasks becomes one of the most important. Nonstandard usage of the service desk system as a basis of the computational task tracking and support system can be the solution of this problem. Particular attention is paid to the analysis and the satisfaction of the conflicting requirements to the task tracking complex from the different user groups. Besides the web service kit used for the integration of the task tracking complex and the datacenter environment is considered. This service kit became the main interconnect between the parts of the scientific project support system and also this kit allows to reconfigure the whole system quickly and safely.

    Keywords: service desk, task tracking, HPC, web service.

    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.

    Pre-decomposition of discrete optimization problems to speed up the branch and bound method in a distributed computing environment
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 719-725

    The paper presents an implementation of branch and bound algorithm employing coarse grained parallelism. The system is based on CBC (COIN-OR branch and cut) open-source MIP solver and inter-process communication capabilities of Erlang. Numerical results show noticeable speedup in comparison to single-threaded CBC instance.

    Keywords: branch and bound algorithm, coarse grained parallelism.

    Cloud computing for virtual testbed
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 753-758

    Nowadays cloud computing is an important topic in the field of information technology and computer system. Several companies and educational institutes have deployed cloud infrastructures to overcome their problems such as easy data access, software updates with minimal cost, large or unlimited storage, efficient cost factor, backup storage and disaster recovery, and some other benefits if compare with the traditional network infrastructures. The paper present the study of cloud computing technology for marine environmental data and processing. Cloud computing of marine environment information is proposed for the integration and sharing of marine information resources. It is highly desirable to perform empirical requiring numerous interactions with web servers and transfers of very large archival data files without affecting operational information system infrastructure. In this paper, we consider the cloud computing for virtual testbed to minimize the cost. That is related to real time infrastructure.

    Keywords: cloud computing, cloud storage, modeling of marine environments.
