Sumario: | For the hadronic calorimeter of the ATLAS detector, the TileTransfer has been developed as a Web system to facilitate the transferring of data that are produced during calibration testbeam periods. It automatically searches, stages and provides a link to download the selected data stored at a remote file center. The system has an interface with the Run Info Database, which contains the description of all test beam runs. In order to optimize the file transmission, the system is connected to a central repository that stores information of the latest accesses. Once a client host connects to the TileTransfer, it can become a file server to other users. At the servers, the selected file is split into several pieces and each piece is sent in parallel and built up together in the final destination. TileTransfer allows that the rile administration be geographically distributed, avoiding an overloaded at the central repository. We also foresee the integration with analysis tools by remote Web access and the publication of the results to the whole community. Among the benefits of this proposal, one can underline an effective management of data across the net of users. (11 refs). |
