== 12GeV (High Priority) Projects Suitable for Local Groups ==


* '''Computer monitoring/alarm system'''
** Learn about Ganglia, NAGIOS and similar systems, choose one and implement.
** estimate 4 man-weeks effort
** Status:
*** Paul Letta will probably do this.


* '''Conditions database'''
** Develop conditions database.
** estimate 6 man-weeks effort

*** Mark has design, Dmitry will probably implement this.


* '''Farm manager CODA component'''
** Develop CODA component capable of managing monitoring of level 3 farm system.
** estimate 7 man-weeks effort
** Status:
*** Vardan will probably do this.


* '''Front end readout lists'''
** Develop a generic readout list scheme capable of detecting which boards are in a crate and reading them out efficiently.
** Must implement only those boards listed in operator-chosen trigger configuration.
** Must also document configuration in Hall D database.
** estimate 6 man-week effort.
** Status:
*** Bryan developed crate scan software.


* '''Alarm system'''
** Implement experiment alarm system based on recommendations (earlier task).
** estimate 8 man-weeks effort.
** Status:
*** Current best choice seems to be BEAST from SNS.


* '''Run bookkeeping scripts'''

** estimate 3 man-week effort
** Status:
*** Prototype translation table exists.



== Other (Low Priority) Projects Suitable for Outside Groups ==


* '''Remote monitoring of experiment'''
** Develop system to allow remote monitoring of histograms, EPICS data, etc.
** May be different mechanism for EPICS data, hist, etc.
** estimate 12 man-weeks effort.
** Status:

* '''Info Server for generic information storage and retreival'''
** Investigate and define role for generic cMsg-based info server (a la CLAS), implement if useful.

** Develop top-level experiment control configuration and associated gui.
** Combines run control and slow controls into one interface.
** estimate 6 man-week effort.
** Status:
*** Vardan best suited to do this, not needed unti after 2015.

** Determine where it should run (ROC, EB, both?).
** estimate 6 man-week effort.
** Status:
*** Carl best choice, he's done some work on this already.
