Full-Speed Simulator Meeting

			      22 April 2015


Project Labor Budget Remaining: 56%

********Recent Progress and News:

* Rich has gotten the -sim (real-time sim) and -fastsim options working, as
  well as the flight (non simulation, real-time) version.

********Next Tasks:

**All: Lab-test of the event-callback version for real-time flight on an
       AUV. 

**All: Piggyback sea trial?

**All: Merge with the CVS head.

* Rob: - Figure out how to synchronize and run TRN at full speed.  This
  	 appears to be mostly decoupled from the QNX development.
       - Get CVS running on the Mac.  Either install a Linux VM, or xCode,
         (xFree86?)

* All: Massage the big three GNC tasks + simulator into a single task that
       runs real-time for flight, full speed for simulation.

*******Questions:

* Shouldn't the QNX VM take most of the host CPU during a full-speed sim?
* What is the fastest machine that can run native QNX 4.25?

*******Notes:

Kent - Run original sim on head; results to compare to fast sim.
     - Devise auv-in-lab tests to validate flight code after merge, before
       sea-trials. 
Kent: Will look at test plan for CVS merge of event-callback code.
Rob:  Will work on how to do fast TRN.

To merge our branch with the head we need to:
 * Finish code that triggers Nav on real-time versus sim completion.
 * Review changes with Hans and make a test plan.
 * Possibly piggy back a sea-trial.

******Overall Objectives:

     1. Qnx Vm (Rob)  (DONE)
     	-Desktop
	-Laptop
     2. Synchronize Layered Control(Rich)  (DONE)
     	-Done using event call backs.
     3. Non blocking operation (Rich, Rob, Kent, Hans)
     	-First pass using event callbacks.
	-Second pass moves GNC processes into a single process.
     4. TRN Integration (Rich, Rob)
     5. Testing and Validation (Rob)


*******Past Meeting Notes:
15April:

Rich will have preliminary code next week.

Kent: tests
 * Sim-to-sim comparisons.
 * Simple Lab1.cfg test.
 * Other lab test?  Ask Hans.
 * How to revert code at sea?
   - Parallel head and branch trees on the vehicle?
 * Select potential piggy-back sea days (Hans).

22 April:
 
********Meeting Notes:

Talk to Hans.

Kent may become available the second half of this year.

Afternoon meeting w/ Kent and Hans:

Hans thinks that our design is probably OK, but we need to verify that the
event/callback code doesn't fragment the heap or have a memory leak.  This,
if happening, is probably not apparent in short runs.  So we need to first
run a 24 hr. fast sim while monitoring Qnx sin.  If that looks good, then we
try a 24 hr. deck test.
