Meeting Minutes:  Team Meeting w/ Priya
Time: 04/07/04 @ 6:00PM-6:30PM
Where: MSE Cave
Attendees: Ackley, Boyer, Fry, Wilson
Purpose: Weekly Status Meeting
------------------------------

--- Presented data collected from last 2 weeks ---

Priya's Comments:
*) Try to turn off fault detection timeout - to confirm that 'faulty' 
   graph has consistent spike size

*) See if we can modify JBoss timeout value.

*) Try large fixed size messages.

*) Note: Data shows that with variable sized messages, it is difficult 
   to find parameters to tune the system, as would otherwise be possible
   with fixed size messages.  Any particular optimization value, such
   as fault-detection time, could  get lost in natural variability 
   associated with message size (such as transmission or processing time.)

*) Find sweet spot for Fault-detection.

*) Suggest using throughput as our metric to chase.
   - optimize for some minimum throughput in presence of some number
     of faults.

*) Prepare argument for why optimizing 'x' is hard
   - such as "due to inherent jitter > 4ms due to message size variability.

*) Consider load balancing
   - do we currently  balance load effectively, can we imporove on this 
     despite variable message size?
   - "Predictive Load Balancing" would be very interesting, but unlikely
     there is time for adaquate analysis.

*) Upcoming Schedule
   - Next meeting will be last day for presenting data
   - Week after we will begin work on presentation material

Team Meeting:
Time: 04/07/04 @ 5:00PM-6:00PM
Attendees: Ackley, Boyer, Fry, Wilson
Where: NSH Atrium
Purpose: Prepare for Meeting w/ Priya


New Assignments:
----------------
AB - Run w/ Large fixed messages
   - Turn off fault detector  (modify ReplicaMonitor)
     - do not increase ping period, just increase ping count
   - Redo "faulty variable message size" data
   - Redo multi-client fault-free data

PW - Fix unique MsgID (clientID + timestamp)
   - catch/debug non-unique msgID exceptions
   - Modify MPClient to keep server.

GA - Investigate modifying JBoss timeout value
   - implement round-robin load balancing
     - this will become prioritized load balancing.

CF - Split failure/succeess time
   - Track message size to graphs
