Production and PASTE Meeting, 27th October 2009, CERN Chair: A.Tsaregorodtsev Minutes: S.Paterson CERN: Z.Mathe, S.Paterson, M.Rashid, R.Santinelli, A.C.Smith, F.Stagni Phone: V.Fernandez, R.Graciani, R.Nandakumar, V.Romanovsky, M.Sapunov, A.Tsaregorodtsev, A.Zhelezov Apologies: P.Charpentier, J.Closier 0. Ongoing Action List #10918 - Ricardo commented that the certification machine is almost ready. It was agreed to also install the data management components there. #10919 - Pending an update from Joel regarding the current machine warranty expiration versus SLC4 retirement #11223 - Direct submission to CREAM CE can now be tested at some sites (using volhcb06 as a GridFTP server for testing) #11124 - SVN repository testing, in order to support existing LHCb tools Marco Cl. confirmed the structure of the repository must be different. After some discussion it was agreed to pursue other compromise solutions 1. Production Status Report - Report from the Production meeting FEST stripping and reco-stripping workflows were commissioned last week (see FEST ELOG). Recent problem of productions defined with incorrect event type comes from request definition, we need to impose a tighter coupling between the simulation conditions and the options files in the processing pass in the future. - Jobs in short queues in CC/IN2P3 Ricardo will dig out some pilot JDLs, under investigation. - Lemon sensors/alarms for DIRAC services Roberto asked whether LHCb is wanting to exploit the 24/7 coverage provided by Lemon. These sensors have been successfully deployed at the system level and it was agreed to extend the functionality to catch situations where e.g. no swap space is available such that the DIRAC experts can be notified prior to a situation becoming terminal. Roberto agreed to investigate a list of hardware conditions to monitor and possible actions to take starting from the existing Lemon sensor tests. ( ACTION: Roberto ) FIO conveyed that the mechanism for interrogating the bqueues was quite heavy, this will be checked in the timeleft utility. 2. DIRAC Release Update The v4r20 release notes are available and Andrei will proceed to release this for central machines and pilots. 3. DIRAC Tasks - Infrastructure monitoring (SAM,SLS,Dashboard) Space token disk occupancy, including pledge information is now available in a table. It was suggested to convey the recipe for obtaining this information to Matvey such that a DIRAC portal page can be constructed. SAM tests are not yet fully translated into Nagios probes but this has been demonstrated. The XML descriptor of our topology of tests and services is being prepared. Federico exposed a method to start publishing information on site-level web pages and is waiting for Matvey to create a prototype. - Bookkeeping status All new features are present in v4r20. These include the run lookup and the propagation of run numbers to descendent files. Also automatic counting of event input statistics in case it is not provided. - WMS status Support for CREAM submission via the WMS was added in v4r20. Stuart reported that the BK ancestor files optimizer functionality was resurrected. - DMS status Andrew updated the SRM2 plugin to allow to list large directories using gfal. Large productions going through validation of output data were becoming stuck due to this. The production management transformation agent is now equipped with 'by run' plugins. File migration monitoring is added for T1D0 uploads, this will be integrated with the stager. A script has been developed to create web pages from a database table, this is not yet released but will be shortly. - Production Management status Alexey mentioned that there will be simplifications for browsing requests on the request page. - Services deployment ( hardware, configuration ) Discussed above. 4.

09:30 → 10:00 Ongoing actions

The task list is available via the Savannah DIRAC group ( Task List ). If you are not already registered please do so at the Savannah page. In order to streamline the time spent during PASTE on the actions list only tasks in the status 'ToBeDiscussed' will be discussed there. In case some actions fall by the wayside they will automatically be updated to this status. Therefore the action assignees should take care to update this. For ongoing actions it is advantageous to report any progress in the Savannah tasks each week.
