/group/halld-online

Now exists with initial allocation of 10 GBytes. Accessible by people in the halldonline group (no "-" in group name, don't know why). Currently mounting this area must be approved on a case-by-case basis. Once the hall networks are set up access will be allowed via IP ranges.

Collaboration meeting schedule

The updated schedule includes talks by Alex and Hovanes. Due to increased activity it appears that one two-hour session at the collaboration meeting may not be enough. Later...I talked with Curtis and we will split the Online session into two sessions at the next meeting, most likely split being Electronics/Trigger and DAQ/Monitoring/Controls.

Networking

Plans for interim and permanent networking in the hall, counting house and tagger area have been worked out with the CC. Plans for getting interim networking to the trailer are still developing, most likely scenario is to run fiber to the trailer on poles.

Farm Manager

Vardan presented plans and options for development of a farm manager controls component. Note that this is a prototype for all controls components in the hall. Next step is to create a top-level Experiment Control Supervisor with an associated GUI. See his slides for more details.

• Based on AFECS system used in DAQ run control.
• Farm Control Supervisor (FCS) not necessarily a CODA component, but this is possible. Recommendation is to not do this.
• Two agent types used: hardware control agent (HCA) and process control agent (PCA).
• Both agents have multiple states, not necessarily identical to run control states.
• One pair of agents deployed on each farm processing comnputer.
• Both IPMI and SNMP supported, but IPMI is newer and has improved capabilities.
• COOL database used to configure agents and specify states.
• Some functionality overlap with NAGIOS and similar packages, can coexist without interference.
• Many options for visualization: custom GUI, use EPICS BOY, etc.
• Prototype code available now, report within a week or so.
