    ALICE computing update before start of RUN2
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 415-419

    The report presents a number of news and updates of the ALICE computing for RUN2 and RUN3.

    This includes:

    – implementation in production of a new system EOS;

    – migration to the file system CVMFS to be used for storage of the software;

    – the plan for solving the problem of “Long-Term Data Preservation”;

    – overview of the concept of “O square”, combining offline and online data processing;

    – overview of the existing models to use the virtual clouds for ALICE data processing. Innovations are shown on the example of the Russian sites.

    Keywords: GRID, ALICE, CERN, LHC, WLCG, CVMFS, Virtualisation.

    Applications of on-demand virtual clusters to high performance computing
    Computer Research and Modeling, 2015, v. 7, no. 3, pp. 511-516

    Virtual machines are usually associated with an ability to create them on demand by calling web services, then these machines are used to deliver resident services to their clients; however, providing clients with an ability to run an arbitrary programme on the newly created machines is beyond their power. Such kind of usage is useful in a high performance computing environment where most of the resources are consumed by batch programmes and not by daemons or services. In this case a cluster of virtual machines is created on demand to run a distributed or parallel programme and to save its output to a network attached storage. Upon completion this cluster is destroyed and resources are released. With certain modifications this approach can be extended to interactively deliver computational resources to the user thus providing virtual desktop as a service. Experiments show that the process of creating virtual clusters on demand can be made efficient in both cases.

    Keywords: virtual machine, lightweight virtualisation, application containers.
