1222 2958d 10h werner / public SVN  
1221 2958d 10h werner /branches/ public SVN  
1220 2958d 10h werner /branches/version1.0/ Version 1.0  
1218 2958d 12h werner / clean up repository - make 1.0 trunk again!  
1217 2958d 12h werner / clean up repository - make 1.0 trunk again!  
1164 3174d 11h werner /branches/iland_regen/src/ found unexpected behavior of irandom(): obviously, it return *never* the upper bound.
eg. irandom(0,3) -> values 0,1, or 2, but never 3.
changed calls to irandom() accordingly.
added also a better random selection of species in the establishment routine
 
1160 3175d 10h werner /branches/iland_regen/src/core/ bug-fixes of the new establishment module (carbon)

first part of the YNP water limitation in establishment.
 
1157 3176d 19h werner /branches/iland_regen/ merge of changes in the trunk (up to the version used for the 2016 DICE simulation batch).  
1104 3246d 17h werner /branches/iland_regen/ Branch dedicated to playing around with establishment/regeneration.
Goals are:
(i) speed up
(ii) introduction of new features for Yellowstone
 
1001 3596d 12h werner /branches/port_qt5_64bit/src/ removed some of the "DebugTimer" --- they tend to cause problems especially when multi-threading is enabled.  
802 4097d 18h werner /branches/port_qt5_64bit/ merge from trunk up to revision 801  
779 4230d 12h werner /branches/port_qt5_64bit/  
764 4420d 07h werner /trunk/src/ implementation of advanced external seed input. Around the project area a "seed belt" is lain. The simulated rectangle is split into sectors which can have a different species composition. At the beginning of the simulation, the external seed maps are populated and then reused each year.  
707 4761d 14h werner /trunk/src/ rework of the random numbers in iland.
Now, many (200000) random numbers are precalculated using a given algorithm (there are three or four choices), then the drandom() etc functions read from this array. After some rotations, the numbers are renewed. The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete.
 
697 4770d 09h werner /trunk/ Doxygen documentation revisited.
After re-establishing doxygen documentation (last update: 2009) a lot of smaller/medium documentation fixes.
Documentation is something that could definitely be always improved ;)
 
671 4813d 13h werner /trunk/src/ Necessary changes for GPL licence (i.e. headers in all source files)  
639 4974d 10h werner / move current content to the "trunk"  
615 5033d 14h werner /src/ removed windows specific _isnan() calls  
577 5074d 08h werner /src/ add 'basalarea' variable to Tree; rename 'speciesindex' to 'species'.
add species names as constants
 
575 5074d 15h werner /src/ * renamed toString() from IException to message() (several occurences).
* added a "name" property to the MapGridWrapper
 
534 5129d 14h werner /src/ large(r) update of the soil model. Now, the 'kyl' and 'kyr' parameters (i.e. decomposition rates for the litter/wood-soil pool) are now species parameters and calculated dynamically from the litter inputs.  
479 5185d 07h werner /src/ pro-file: found a way to use debug symbols in release mode: one has to also alter the link-flags to disable stripping of symbols during linking.
fixed a bug in seed dispersal.
 
475 5185d 15h werner /src/ * Snag dynamics
debug output "SnagDynamics"
life cycle of Snag objects
include Snag Dynamics in newYear / year end routines

* threadrunner.cpp: parallel execution of species related tasks, e.g. the seed dispersal. In the current form, the ThreadRunner is much nicer:
ThreadRunner runner(mActiveSpecies);
runner.run(func_ptr);
 
470 5189d 19h werner /src/core/ add light response function to sapling growth (rest: constness of lightresponse function calls)  
428 5321d 15h werner /src/ added linearization for some expressions (e.g. light response), and a global switch to enabled/disable the linerization using one static boolean (triggered by a iland setting)  
425 5322d 16h werner /src/ made the calculate() and execute() function of Expression const (using a trick), so there is no more need for un-const functions which should be const (e.g. in Species).  
420 5323d 07h werner /src/core/ removed the QMutex and the QMutexLocker for serializing the execution of expression evaluations. This is no longer necessary, because Expression::calculate() now is reentrant.
The performance effect of this change is awesome: the time used to grow individual trees drops by ca. 40% (the total runtime is maybe 5-10% faster) (tested with iLandSpeed.xml -> 2x2km)
 
415 5323d 16h werner /src/core/ seed dispersal:
* defining synchronized seed years for each species
* use different seed kernels depending on seed year state
* create two kernels for each species (1x seed year, 1 x non-seed-year)
* newYear() function also for each Species
 
393 5348d 17h werner /src/ fixed a bug in StampContainer when loading trees with invalid hd-ratio (too low trees).
fixed a bug that caused a crash when seed dispersal was disabled.
added return values for stand init routines (also those that accessed by scripting) and cleaned up the documentation.
 
391 5350d 14h werner /src/ a rather large update mainly in course of the implementation of seed dispersal.
* integrating the seed dispersal within the model logic
(new function e.g. SpeciesSet::newYear() or SpeciesSet::regeneration()).
* SeedDispersal: implementation of the Seed-Kernel a la TreeMig (see the R-Script on dispersal by Rupert)
Additionally:
new functions (sum(), multiply() for the Grid-template.
 
387 5351d 07h werner /src/ integrating seed dispersal into the model
moved global constants for grid sizes into globalsettings.h
 
318 5498d 18h werner /src/ AJFZ-troubles; changes during setup of environment (added some error messages, improved path handling, ...)  
298 5520d 10h werner /src/core/ comments  
274 5546d 09h werner /src/ lightResponseClasses (changed in SpeciesSet, Species and Tree)  
270 5546d 23h werner /src/core/ added warning if species table not found  
214 5563d 02h werner /src/ finished Phenology. lots of related changes.  
213 5563d 05h werner /src/  
211 5563d 07h werner /src/ Phenology class and things that come with that.  
210 5563d 10h werner /src/ class "Sun", added "site"-varaibles to the project file.  
209 5564d 02h werner /src/ Environmental responses:
VPD, Temperature, CO2, Nitrogen
