new optimized establishment routine.
not finished yet, but looks promising in my first tests. |

renaming of the FOME to AMIE.
unfortunately, some partial merge of changes in Qt4-branch. |

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). |

fixed a problem when trees died in disturbance and the (unupdated) statistics were used (e.g. the LAI for calculating the water cycle). Now for affected resource units, not only the treelists but also the RU-statistics are updated.
implemented a "radiating" mechanism of border cells. If stand-grid-cells (i.e. 10m height grid resolution) are marked as "outside and forest", then the cells "radiate" some influence on the LIF into the project area. Thus, trees on the edge of the project do *not* have properties of trees standing on a stand edge. Currently, the form/amount of this edge-effect is hard coded. |

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 The point is: this is now reentrant, so the per-thread storage of MTRand objects is obsolete. |

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. |

continued to work on the fire module. Include the fire severity (i.e. mortality due to fire). This had various other impacts, e.g., on the carbon cycle of saplings. |

corrected grid export (flipping of y-axis)
added initialization of saplings; StandLoader contains now a routine similar to the one for larger trees to distribute saplings; additionally, a script function (Globals.addSaplingsOnStand()) can be used to use this functionality. |

* modified outputs to write only rows for valid resource units
* dropped setting "woodDecompRate" (snag.cpp)
* calculate the "stockableArea" of a resource unit based on the stand grid
* use the stockableArea for calculation of LAI |

some performance optimizations done on Linux with valgrind /
KCacheGrind.
stamp: did inlining of "distanceToCenter" (is still relatively expensive
due to heavy usage in e.g. applyLip)
Saplings: removed the very exensive way to check if a sapling of a
species is already on a given pixel; we now use a std::bitmap for that
purpose.
grid: optimized the "indexOf(float*)"-method; this method is used very
often. |
