38. General status
Need to freeze v4-19-Release for the coming PbPb collisions
Outstanding issues: low success rate (95% in pp, ~50% in cent1 PbPb)
Memory consumption
CPU consumption
Reconstruction of RAW data with many PbPb events: not tested
Several commits still needed, see the requests on the next page
Proposed solution
Run MC for 1000 central PbPb with every new tag (already done, see LHC10f8*). Store all files; store also everything from the failing jobs
Run QA macros on the successfully produced events
Discuss the results at QA and FHIP meetings and fix the issues
Important condition
Participation of the FHIP members in the weekly offline meeting

39. Coverity Good response in general
Still adding new defects while fixing the old ones

40. CPU: PbPb simulation

41. CPU: PbPb reconstruction

42. Memory: PbPb MC production
