Minutes

Present: Elliott W, Beni Z, Mark I, Dave L, Simon T, Hovanes E, Yi Q.


Translation Table

Dave is working on implementing a translation table in JANA. He starts by reading in evio raw data and creating raw hit objects indexed by crate/slot/channel and module type. The translation table is needed to convert this to detector coordinates (e.g. row/col for FCAL, etc). Many aspects were discussed, e.g. whether to store in XML or just store the SQLite file he uses; at start of run store table in calibration vs condidtions database; sweep from conDB to calibDB to allow for history mechanism; when should changes to conDB be allowed; do we even need the conDB?


Build System

Elliott presented the build system that is checked in and installed (see link above for many details). A first development release exists in /gluex/builds/devel. He created a full set of package creation and building scripts. Mark and Dave suggested some minor name changes and help improvements. Dave will develop the final script needed in the online build/release system, one that automates setting of the relevant environment variables.


Counting House

Hovanes reported that equipment continues to arrive, and everything should be here by July. Chip's large computing order has been delayed since he's waiting for a new chip architecture to become available (Ivybridge vs older Sandybridge). This is not interesting to us as we do not need the fastest cpu's, we just need the most cpu per dollar. But it appears we are doing fine with the computers currently installed so we likely will postpone our purchase to try to get a better price as part of Chip's larger order.


At this point we broke for the Run-A-Round (later: a good time was had by all!)
