Full-Speed Simulator Meeting

			      8 April 2015


Project Labor Budget Remaining: 59%

********Recent Progress and News (2 weeks ago):

* The Event-callback code is now running with a speed up of *** x 17 *** on a
  full-up simulation that includes octree ray-tracing.

* Rich and Kent have solved the "interrupted function call" error.

********Next Tasks:

**Rich: Add flags -fastsim and -sim that run the simulator fast and
  	real-time, respectively.

**All: Devise and perform tests of the event-callback version for real-time
       flight.  Piggyback at sea?

**All: Merge with the CVS head.

* Rob: - Figure out how to synchronize and run TRN at full speed.  This
  	 apears to be mostly decoupled from the QNX development.
       - Polish up Simulator.cc so that we can more easily switch between
  	 missions, e.g. wall following versus bottom following.
       - 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:

* What is the fastest machine that can run native QNX 4.25?
* PST stuck on sandpiper-qnx, but now fixed?


*******Last Meeting:

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. 

Rich: Hopes to have added flags for real-time and full-speed simulation in 2
      weeks - 16th.
Kent: Will look at test plan for CVS merge of event-callback code.
Rob:  Will work on how to do fast TRN.

*******Notes:

To merge our branch with the head we need to:
 * Finish code that triggers Nav on real-time versus sim completion.
 * Down-merge the ongoing head development first.  
 * 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)
