Minutes

Present: Elliott W, Bryan M, Simon T, Hovanes E, David L, Carl T, Eugene C, Dave A.


Hall D Accounts

See proposal in Wiki above. Everyone agreed to start with the simple strategy and use ssh to special accounts instead of passwords. Later Kelvin was happy with our strategy.


Online Build System

There was general agreement to start by testing Maurizio's SCONS system on sample online code. Elliott will give it a try with some of the farm node testing code he recently developed. We will stick with the Offline group's Make system for JANA-based software.


Level 3 Farm Requirements

See Dave's slides for full details. Dave currently achieves 22 Hz per core performing all the analysis in his slides. Optimization may decrease this, e.g. by using a staged approach and/or multi-dimensional techniques to allow a decision to be made before all the analysis is performed. Note that wire-based tracking takes 2/3 of the cpu time.


Simulated Raw Data

Dave L found misformed events, it is not clear if the problem is in his code or Dave Abbott's mc2coda package. Dave is almost done decoding mc2coda raw data, next up is mc2coda compressed format. Eventually the translation table will have to be implemented in JANA in a standard way to convert from crate/slot/channel to detector coordinates.
