Summary of data management meeting Monday, March 15th, 2004 16:00 Bat 2-R030 ============================================================================== Present: N.Brook, P.Charpentier, J.Closier, M.Frank, R.Graciani, G.Kutznetsov, J.Saborido, A.Tsaragorotzev, R.Vizcaya Workload Management System (Andrei, Ian, Vincent): - Information service is installed on lbnts2 to serve status reports etc. - Input data are accessible through the file catalog - Agent was modified and executes a job being a collection of modules. - The production database must still be interfaced to produce proper JDL scripts for the job submission. - Asynchronous updates of the file catalog and asynchronous data transfers must still be implemented. Monitoring and accounting (Ricardo): - Accounting must be integrated into DIRAC Data Management tools & hardware (Joel/Andrei): - Access to datasets stored in castor is possible from LCG2. Castor is a known storage element, the datasets produced in LCG2, which are stored in castor are also visible for regular batch/interactive jobs. Other storage systems must be tested. - The AliEn file catalog has an interface, which allows to generate POOL XML catalog slices. - In order to implement catalog synchronization between LCG/EDG-RLS and AliEn a naming convention is required. Andrei suggests 2 levels: /// The first "real" physical file name is the name of the file in the local storage element ie. on the Grid this will be the grid storage name. - Andrei is now happy with the support of the Lxgate05 machine. Production database/XML catalog/bookkeeping (Markus): - Script to generate slices of the XML catalog needs better error reporting. - Andrei will send the file catalog interface he expects to be provided by the bookkeeping database to Markus. Markus will implement the read-only part of this interface for the existing bookkeeping database. - The production database must be populated with proper workflows in order to test a real execution environment. Dirac desktop (Gennady): - Implementation based on SOAP done. - The output XML job descriptions are not yet tested. Minutes: Markus Frank
