Round Table
Marco Cl.
- Testing LCGCMT new structure
- ROOT 6
- unstable in the last few days, but we have a chance of getting a tag before the weekend
Joel
- Created virtual machine with 500GB of disc,
- LHCbDirac ready to move to Python 2.7
- still issues with the way middleware libs are built (problems with the externals)
- PID Calibration required disc space to store ~100 GB of calibration data. They asked for AFS, but they will get a storage element (EOS space).
Illya
- The shutdown of Neo4J was not a clean one, triggering a bug in Neo4J that caused the explosion of the number of entities. In any case there was no corruption.
Gloria
- Issue with the build of Geant4 examples (clashes of file names), Marco Cl. will look into it to prepare a prototype requirements.
- G4 examples are needed to run regularly tests to be published to LHCbPR.
- Next week there is the LPCC workshop.
- Paul will present our plans for Geant4 10 and multithreading
- Marco Cl.: added handling of platform-independent generated files in the nightlies (only for Geant4 and DecFiles)
Ben
- Provided Benedikt with a script to generate the RPMs we can install. Being tested.
- Working on the packaging as RPMs of our projects.
- Testing of CVMFS server is going well:
- it nicely handled disc full
- we need a garbage collection on stratum-0, to remove the history (developers are working on it)
- we should move to production for the nightly builds installation
