    Security & Networking
    In grid computing we use an X509 PKI security infrastructure. This infrastructure is used to enable secure connections between hosts to deliver payload. This often leads to scalability and reliability issues. This talk presents the alternative approach of signing messages for asynchronous handling, allowing authentication of the payload rather than the connection. The implications of this...

    Computing & Batch Services
    In order to improve its batch service for local and Grid users, development is ongoing at CERN to design a batch monitoring system and set up a test instance. The goal is to enhance the batch service by investigating new scheduler features, fine-tuning the already used ones and decreasing the time spent in problem identification and fault resolution.

    Virtualization technology has been applied to a variety of areas including server consolidation, High Performance Computing, as well as Grid and Cloud computing. Due to the fact that applications do not run directly on the hardware of a host machine, virtualization generally causes a performance loss for both sequential and parallel applications. This talk studies the OpenMP applications...

    Reliable benchmarking of file systems is a complex and time consuming task when one has to test against a production environment to achieve relevant results. In case of the HEP community, this eventually leads to setting up a particular experiments' software environment, which could be a rather complicated task for a system administrator. To simplify this task, we developed an application ...
