Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better.

(S. Beckett)

+To be followed up

LHC12f being processed smoothly

LHC12e done, waiting for LHC12d

LHC12d being processed with Rev-22, failures in T0, and TRD

LHC12c manual update ongoing

pA MC test on LHC11f2 ongoing (merging will be submitted today)

pA data run 187338, done at CPass0, but no info on MonALISA, not appearing at CPass1 snapshot

pA pilot run CTP will have a Alias file with everything defined as kCalibBarrel (to my understanding)

8/28/12C. Zampolli

2

+To be followed up – II

kCalibBarrel triggers number published in logbook (waiting for news, promised by the end of August)

Validation codes from the detectors still missing TPC and MeanVertex, will help for short runs failing in TRD due to statistics

Replicating the OCDB entries: new functionality implemented by Raffaele how should it be implemented in the calib code? Member of the AliCDBManager? Otherwise everybody will have to change their code…

Reprocessing of old runs trigger classes defined, Aliases file to be created, then downscaling

Better selection of runs? Difficult in my opinion

8/28/12C. Zampolli

3

+Some diagnostics

During the last 2 months of CPass0/CPass1 processing, (quite) some manual intervention was needed Fixing steering macros/scripts Restarting CPass0 and/or CPass1 Triggering CPass0 and/or CPass1 manually

Main reasons (to my memory… I might forget something) Wrong AddTaskTPCcalib.C committed to the release by mistake during

synchronization Merging of syswatch trees not properly tested and consuming too much

memory TPC wrong OCDB update in makeOCDB.C macro for CPass1 Wrong TPC gain threshold used for validation

8/28/12C. Zampolli

4

+Some diagnostics – II

Reprocessing of LHC12d due to a bug in the TRD reconstruction Re-reprocessing of LHC12d due to a problem with TRD code in Rev-23 Some LHC12e runs to be reprocessed after a fix in the aliases files due to

“miscommunication” (mis = missing + wrong) between TRD, RC, Trigger, calibration

CPass1 manual triggering for runs failed in T0 at CPass0 (1 done, 20 to be done)

CPass1 manual triggering for a run for which CPass0 was merged manually (Raphaelle)

CNAF disk full ALICE::CERN::T0 issue

8/28/12C. Zampolli

5

+Two more comments…

As already said in July, no modification in AliRoot that may affect the calibration should be requested to be ported to the Release if not properly tested in the calibration train on the grid I cannot know whether changes may affect the calibration, the detector

experts should

Since apparently it is not enough to show updates on Monday Offline, Tuesday RC, Thursday Offline Calibration Readiness and Friday Calibration usual meetings, I think it would be important that: One person representing all the detectors taking part in CPass0/CPass1

should always be present at the calibration meetings If the direct responsible(s) is not available, someone representing the

corresponding detector should anyway participate, to propagate the information discussed there.

8/28/12C. Zampolli

6

+How to decide when to process a run

Currently, we process runs marked as good (DAQ flag), duration > 5min, GRP ok, with Beam Could this be improved? Hardly to say… Not on the offline side at least…

+TRD issue

Due to a problem in the TRD reconstruction, some wrong OCDB entries were produced at CPass0; it is not possible to get the correct ones without re-running CPass0 Some manual OCDB update is needed (after LHC12d is fully processed,

ongoing for completed runs) DONE Then CPass0/CPass1 should be re-run with a Rev > Rev-18

Rev-23 (the latest) was used Changed in TRD code made the calibration not work properly More tests, new re-running with Rev-22

Will the failed runs be recovered? Waiting for experts’ reply still not known

Since MB will be the main trigger, we propose to use that and downscale. For the pA pilot run, all data are asked to be reconstructed, keeping ESDs,
