Notes
I have to apologize to the attendees trying to call the phone conference. For a reason that I do not know yet, the system was not letting me in.
Subjects
News
- LCG 47b delayed because of a bug in ROOT
. The build of a fixed version should be ready during the morning. COOL and POOL will re-run the tests.
Software Releases
Gaudi (Hubert)
- v19 still on hold
- v18r8 ready, just waiting for LCG 47b
- Changes in the properties of DataOnDemandSvc (Vanya)
- Few problems were encountered on AMD64
- lxplus machines do not have enough memory to compile the Parser
- problems with random seds
- problems with ROOT
LHCb, Boole, Brunel (Marco Ca.)
- Stuck after the discovery of the problem with Reflex
- Next release (Brunel) will be early next week (with new Gaudi and new LCG if they are ready in time).
- The following release will be at the beginning of November.
Gauss (Gloria)
- v25r4 released last week and used in production.
- 4-5 failure for time-out from IN2P3 (Andrei is aware of the problem)
- A build of v25r5 (~ identical to v25r4) with the new version of GENSER is available in DEV for testing.
DaVinci (Marco Cl. for Juan)
- Test jobs with pre-selections exposed variuos problems (fixed by Juan and Patrick)
- DaVinciAssociators revers association have problems. Olivier found a possible cause, but the solution requires big changes (not ready yet).
- Problems with calorimeter association: require latest versions of Calo/CaloReco and Calo/CaloUtils.
- No Brunel v30r10 in the book-keeping. He will ask for a small production (~10K events) to test the pre-selection.
- Matt committed changes in DetDesc to speed up the transport service (few functions made inline).
Panoramix (Thomas for Guy)
- Pending issues on dictionaries and ROOT.
Round Table
- Gloria
- It happened twice in one week that files ready to be migrated wait for days.
- Thomas
- We should probably do some clean up in CASTOR. Marco Ca. reminded that we do not have anybody for that task.
- Markus
- There are efforts in ROOT to be able store vectors of pointers as branches of a tree (as it happens with TClonesArray). If we move to it, we will not be able to read back old data. Anyway it is not going to happen soon.
- Marco Cl. and Florence
- After the iscussion of last meeting concerning the possibility of overriding the version of LCG externals like CASTOR, the are implementing a solution based on SetupProject and CMTUSERCONTEXT, with changes in install_project.py to be able to disptribute tarballs with the new versions of the needed libraries. The system is half ready: if you use SetupProject at CERN for an application based on LCG 46, you will use CASTOR 2.1.1 (LCG 47) instead of 2.1.0.
