Production and PASTE Meeting, 15th September 2009, CERN Chair: S.Paterson Minutes: S.Paterson CERN: P.Charpentier, J.Closier, Z.Mathe, S.Paterson, M.Rashid, R.Santinelli, A.C.Smith, V.Romanovsky, F.Stagni Phone: A.Casajus, R.Nandakumar, M.Sapunov, A.Zhelezov Apologies: R.Graciani, A.Tsaregorodtsev 0. Ongoing Action List SLC5 testing, new binaries should be deployed today or tomorrow as many sites are migrating already. - Production request page update Alexey is waiting for a response from Matvey about how to open certain productions in the monitoring page. A more optimized BK query in order to obtain the number of events would be advantageous. 1. Production Status Report - Report from the Production meeting The recent SSL Handshaking errors affecting the Matcher caused a ramp-down of running jobs and should be investigated. ( ACTION: Adri ) Apart from the 10% failure rate still happening with Gauss, production is running smoothly. - Set up stripping workflow(s) Ongoing pending DaVinci release. - ELOG deployment The suggestion to deploy the ELOG on one of the offline machines was discussed, during the meeting Olivier sent a mail conveying this was understood. It was decided to continue with the current situation given that we now have a support mailing list to rectify problems. - Production status updates With the developments from Stuart and Andrew, there are two new agents governing the production status machine, documentation for this will be prepared. ( ACTION: Stuart ) 2. DIRAC Release Update The status of the v4r19 candidate release is not clearly understood. There was some discussion regarding the SVN migration and we were pending updates from Marco regarding the structure. 3. DIRAC Tasks - Infrastructure monitoring (SAM,SLS,Dashboard) Roberto mentioned that one test has been demonstrated in the Nagios infrastructure. In addition there is an alarm system for available storage space at the Tier-1 sites (excluding T1D0). - Bookkeeping status Zoltan implemented a method to summarize the events for a given event type and also the productions for a given configuration name and version. Philippe wondered where we are with the BK documentation and Zoltan will add the link to the 'help' button. Matvey mentioned the progress with the BK web interface, some cases should be tested with Zoltan. - DMS status Recent work has been on the data integrity tools. The integrity client can now perform all possible checks and methods to resolve different kinds of problematic files are being provided. This is ongoing as a decision tree may be implemented to streamline the code. - Production Management status Production status machine has been modified as discussed above. - VO-boxes Raja mentioned that things are stable on the VO-boxes. - Web Portal A certification instance of the web portal would certainly be useful in order to improve the release cycle. For now a machine in Barcelona will be used. - Services deployment ( hardware, configuration ) Raja mentioned that the VO-boxes will be updated to SLC5 with a medium priority so we should be ready for this. 4. AOB The issue of testing pilot submission through the CREAM CE was raised by Philippe. After some discussion it was agreed that submission to the CREAM CE should be demonstrated at least as a test. ( ACTION: Stuart, Ricardo ) Several LHCb people have been added to the WLCG Technical forum list. The intention behind this group is to identify major problems from experiments and sites and convey these to the middleware developers. Preparations for the EGEE demonstration in Barcelona are ongoing, Roberto has a movie from Stuart for production requests. For the Ganga part there will be some coordination with Andrew Maier. Philippe reminded that there will be a mini-workshop on virtualization scheduled for the Friday of the software week, internal to LHCb.

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.

10:00 → 10:30 Production issues

- Report from the Production meeting - Stripping workflow(s) - Processing real data by runs (i.e. not mix runs at any stage) - Disk quota implementation

10:30 → 10:50 DIRAC Release Update

As agreed at the last PASTE meeting a weekly update on the status of upcoming releases will be discussed here.

10:50 → 11:20 DIRAC tasks

- Infrastructure monitoring (SAM,SLS,Dashboard) - Framework status - Bookkeeping status - WMS status - DMS status - Production Management status o production job post-execution checks - VO-boxes - Web Portal - Services deployment ( hardware, configuration ) - Documentation

11:20 → 11:30 AOB
