Revision as of 15:30, 9 April 2008

Overview of online systems
Foundations
- cMsg pub/sub interprocess communication system
- ET system
Trigger/DAQ
- trigger setup
- how to adapt CODA toolkit to Hall D
- implementation plans for low luminosity and prototype farm
- scaling to high luminosity and full L3 farm
Controls
- slow controls
  - architecture - 3-tier, functional view vs implementation view
  - strategy - control loops, PLC usage, CAN, I2C, SNMP, OPC, etc.
  - component choices (tentative)
- experiment controls
  - run control using AFECS, inclusion of non-CODA components
  - generic high-level state machines
Monitoring
- detector
  - via slow controls system
  - via data stream when running
- event data quality - via (prototype) farm
- archive/display system - MonAlisa, other possibilities
- event display
Alarm system
- design goals
- epics, LASER, cMsg/CLAS, A-B, others
Misc
- databases - MySQL or PostgeSQL
- run and shift bookkeeping
- e-log - CLAS, CRL or other public domain, write one yet again, etc.
