Announcements

CCDB 0.5

Mark called our attention to a recent [??? announcement from Dmitry and him] on the latest release of the calibration database. The code is built on three platforms at JLab and there are instructions on how to use it with Jana in the file ccdb_0.05/janaccdb/READNE.txt.

Major changes on JLab batch farm

Mark went over the [??? recent announcement from Scientific Computing] at JLab on changes to the batch farm going in today and possibly tomorrow. There are many fundamental differences being rolled out in Auger and Jasmine so users should be on the lookout for anomalous behavior and report any seen. You will have to have a new scientific computing certificate to use the farm.

Scientific Software Support Committee

Mark told us about a new committee that will oversee support for scientific software packages at the Lab. Chip Watson proposed the existence of the committee and the first meeting was held last week. The committee will be joint between Physics and IT. Graham Heyes will act as chair. The initial initiative will be to integrate ROOT, CERNLIB, Geant4, etc. into the normal support structure of IT Division, mainly helpdesk service and documentation. The actual support of the packages will remain with the current responsible individuals for now. though that may change going forward. In the future the committee may help decide which packages should be officially support by IT.

Detector naming scheme

Elliott called our attention to the detector abbreviation scheme Fernando Barbosa has urged us to follow. He noted that there are several instances where the naming scheme in the code does not match that of Fernando's. We thought that consistency would be nice, but questioned whether this was an important front-burner issue for this group. We decided to back-burner it and perhaps discuss it again in the future.

More on raw data, occupancies and anomalies

Elliott described recent progress on online monitoring using the new EVIO format data. He outlined plans and showed histograms from the prototype monitoring plug-ins he has written. He solicits feed back and contributions from the detector groups to develop their respective packages further.

Review of minutes from the last meeting, geometry changes

We went over the minutes of the ??? meeting.

David recently made some changes to the BCAL geometry to fix volume overlaps reported recently by Simon and by Richard some months ago. Simon also checked in a change to the FDC geometry so that it matches the inner radius of the BCAL. David did a radiation length scan and saw an increase in the amount of material inside the BCAL caused by the cable material being "revealed" when overlap was removed.
