Review of minutes from the last meeting
We looked at the minutes from the last meeting. Elliott remarked that in the translation tables there was no need to identify the pre-amps for the tracking chambers as separate entities.
Status of the CCDB release
Dimitry is finishing the conversion from existing Subversion-controlled calibration constant files to the CCDB
- built JANA, put in classes to read CCDB
- getting ready to test
- should be done in the next few days
- CCDB has been checked into the 12 GeV Physics repository
Elliott commented that some progress on the conditions part of the CCDB would be useful.
Update on non-deterministic event reconstruction
David has found and fixed a problem, first reported by Will, where repeated reconstruction of the same events with the same binary reproduced different results. See David's message for details of the fix.
Paul reported a different bug and checked in a fix. This was giving different figure-of-merit values for repeated executions at the 1% level. See his message for details.
- We discussed using NaN (not a number) as a signal that a variable is not defined.
- We discussed a problem with the new hit generation in the tracking chambers where the maximum number of hits is reached. Simon will raise the limit in the software.
- Dave asked Paul when the high-level particle class reorganization would be finished.
- Dave wondered if the Subversion servers could be configured to store passwords in an encripted form.
- Will pointed out that the weekly b1pi jobs are not regularly looked at for success or failure. He volunteered to help with this. Dave pointed out the utility root2email that might help with notification.
- Mark noted that the nightly build was now broken. This has been the case since the change in the roster of ifarm machines.
