    Integrating OSG Operational Services
    (2012-09-20) Quick, Robert E.
    This contribution will address experiences with the CA switch and integrating it with OSG existing Operational Services (Topology DB, Monitoring Services, Wiki's, Ticketing, etc.), and will provide information about the OSG plan towards the adoption of SHA-2 in its PKI.

    OASIS: a data and software distribution service for Open Science Grid
    (J. Phys.: Conf. Ser. 513, 2014-06-11) Quick, Robert E.; Teige, Scott; Bockleman, Brian; Hover, John; Caballero, Jose
    The Open Science Grid encourages the concept of software portability: a user's scientific application should be able to run at as many sites as possible. It is necessary to provide a mechanism for OSG Virtual Organizations to install software at sites. Since its initial release, the OSG Compute Element has provided an application software installation directory to Virtual Organizations, where they can create their own sub-directory, install software into that sub-directory, and have the directory shared on the worker nodes at that site. The current model has shortcomings with regard to permissions, policies, versioning, and the lack of a unified, collective procedure or toolset for deploying software across all sites. Therefore, a new mechanism for data and software distribution is desirable. The architecture for the OSG Application Software Installation Service (OASIS) is a server-client model: the software and data are installed only once in a single place, and are automatically distributed to all client sites simultaneously. Central file distribution offers other advantages, including server-side authentication and authorization, activity records, quota management, data validation and inspection, and well-defined versioning and deletion policies. The architecture, as well as a complete analysis of the current implementation, are described in this paper.
