    Presentation
    The talk will provide detailed information on one of the most revolutionary platform for low power computing of recent years. The interest on power saving and maintaining a good time to solution performance is the open task of the current research on computing. Our solution based on ARM Cortex-A9 and GPU Nvidia Quadro can achieve 270 GFlops of peak performance single precision with a power...

    Presentation
    Gridengine does not come with a graphical monitoring tool to watch the activity on the batch farm. Commercial add ons like Arco and Unisight do provide limited monitoring based on the contents of a log file which however does contain only a minimum of information on running jobs. Therefore at DESY a batch monitoring software was developed to fill the gap. The system is in place at DESY for...

    Presentation
    Splunk is a commercial software platform for collecting, searching, monitoring and analyzing machine data providing interactive real-time dashboards integrating multiple charts, reports and tables. We have been working on a Son of Grid Engine setup based on the free Splunk branch supporting standard reporting and simple job and fairshare debugging with easy chart generation and smart event...

  5. 9. Job packing: optimized configuration for job scheduling
    Dr Stefano Dal Pra (INFN)

    Presentation
    Default behaviour of batch systems is to dispatch jobs to the lesser loaded host, Thus spreading jobs almost uniformly across all the nodes in the farm. On some circumstances it is however desirable to have some kind of jobs running in the smallest possible set of nodes. Usecases and packing variants are discussed, and test results are presented.
