Review of minutes from last meeting
We reviewed the minutes from the November 17th meeting. No significant remarks were generated.
Announcements
- Nightly builds: The builds are now going on now building without errors, on three platforms: RHEL5 (32-bit only), Fedora 8 32-bit, and CentOS 5 64-bit. Both debug and non-debug versions are created.
- We discussed whether we want to do the builds on other platforms, especially MacOS. For that we would need hardware. No clear path forward presented itself, but we will think about it.
- We also discussed whether we should have automatic notification of errors and warnings. One idea is to have a dedicated email list so people could subscribe the error message stream. Again, on this there was not a consensus; we will raise it again later.
- David noted that a couple of feature that used to be present in the nightly builds have been lost: doxygen documentation tree generation and svn statistics. Mark will look into restoring them.
- New tagged release: release-2009-12-01 This has been built on the three above-mentioned platforms. Release notes and set-up scripts are to come.
- New Subversion server The CNI group is building us a new subversion server. It will be a new virtual machine running subversion 1.4 vs. 1.1 on the old server. The new version will allow locking of tagged releases: i. e., no new check-in's will be allowed for the locked files. Cut-over is scheduled for two weeks from today.
DPhoton, DParticle and how to unify high-level objects
Simon outlined the philosophy behind his recent work on the DParticle factory.
- BCAL clusters, FCAL clusters and charged tracks are all represented as particles
- track matching is done to the outer detectors
- beta is calculated from time of flight
- particle ID is done; a mass is assigned
- time-based tracking results are used
- The DParticle name used to be used by the object now known as DTrackTimeBased???
Sascha thought there should be a way to go back to the original low-level objects. David mentioned that this could be accomplished via associated objects.
dphoton calculates error matrix in lab frame need event vertex factory needed to generate the dphoton object now uncertainty of the vertex location folded into error matrix accessing fits for various mass estimates dphoton: tries to use track information as well
sasha: pid likelihood
cleo: pi k proton fit entrance fits, exit fits
dphoton should use dtrack-time-based for neutral identification
should we use wire-based or time-based for track matching
design to be presented at next meeting
howto written
- Offline Computing Project Management: Mark
- Coding Conventions vote: all
- Action item review: all
