1222 2724d 18h werner / public SVN  
1221 2724d 18h werner /branches/ public SVN  
1220 2724d 19h werner /branches/version1.0/ Version 1.0  
1218 2724d 21h werner / clean up repository - make 1.0 trunk again!  
1217 2724d 21h werner / clean up repository - make 1.0 trunk again!  
1196 2845d 17h werner /branches/iland_regen/src/ StandGPP debug output (instead of the missing StandNPP) output  
1174 2912d 18h werner /branches/iland_regen/src/ fixed a bug in the establishment / saplinggrowth debug outputs (bookkeeping)  
1168 2933d 18h werner /branches/iland_regen/src/ working on serotony, establishment etc. updated new establishment module w.r.t. debug outputs.  
1158 2942d 20h werner /branches/iland_regen/src/ further performance improvements in regeneration/sapling module.
In total (sim 80 yrs WBT 2km2, from bare ground), iLand is +- 35% faster:
* seed dispersal (not today)
* optimized use of LRI-correction
* better linearization in sapling growth (height growth potential)
 
1157 2943d 03h werner /branches/iland_regen/ merge of changes in the trunk (up to the version used for the 2016 DICE simulation batch).  
1104 3013d 01h werner /branches/iland_regen/ Branch dedicated to playing around with establishment/regeneration.
Goals are:
(i) speed up
(ii) introduction of new features for Yellowstone
 
928 3558d 23h werner /branches/port_qt5_64bit/src/ additional debug outputs for the splitting of N mineralization fluxes (that comprise availableNitrogen).  
863 3789d 20h werner /branches/port_qt5_64bit/ renaming of the FOME to AMIE.
unfortunately, some partial merge of changes in Qt4-branch.
 
824 3830d 01h werner /branches/port_qt5_64bit/src/ fixed *big* regeneration bug. The map with the height of saplings on a resource unit was used in the establishment subroutine although it was *invalid*. Now the establishment and the regeneration are (again?) in one function and use the same valid map.
this removed the strange stripes in the regeneration pattern (there should have been crashes, but weren't). Consequently, the performance debug output was modified.
added better formatting to debugtimer.cpp for large times (in hours, minutes, seconds).
 
793 3872d 18h werner /branches/port_qt5_64bit/src/ Move from QScriptEngine to QJSEngine (=V8). Most of the stuff was quite smooth, but there are some open issues.
• Global functions (“print”, “include”, “alert”) are commented out (could be solved by moving functions to the “Globals” object and by creating alias JS-functions, i.e. function alert(x) {Globals.alert(x); } )
• Object creation: “new XXX”, XXX=ClimateConverter, CSVFile, … does not work now
possible solution: factory-pattern (i.e. var csv = Globals.newCSV())
 
780 3983d 21h werner /branches/port_qt5_64bit/src/ Steps to build iLand with Qt 5 and with MSVC compiler and 64 bit.
http://iland.boku.ac.at/blogpost44

removed also a couple of warnings that were thrown by the MSVC compiler.
 
779 3996d 20h werner /branches/port_qt5_64bit/  
767 4175d 13h werner /trunk/src/ larger restructuring of code (moving scripting related parts)
adding a shell for "spatialAnalysis".
In the future, a cleanup of all the "spatial" grids/maps/stuff is necessary...
 
707 4527d 22h 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.
 
705 4528d 17h werner /trunk/src/ series of performance tests / modifications.
Using "valgrind" on the linux virtual machine, some performance
measurements were made.
Some candidates for optimization were tested. (1) the applyLIP()
function (about 30% of total run time in runYear()): here several
inlining options were tested; testing the value of the stamp before
using it (in order to omit the other steps) prooved to be slower than
unsing all stamp values.
(2) the random number generator; here the random number generation is
about 5% of the total run time; the commit contains two/three other
variants.
