[GRASS-dev] r.watershed and swap memory

[Yann Chemin]

hi,

just to complete the comment on r.watershed, large dataset, and large RAM...
After 5+ days I stopped the processing, it seemed that it was becoming
slower and slower with time (i.e. increment of percent), while holding
nearly same memory consumption.

I would guess it was searching something more and more elusive...
Don't know much about the algorithm though.
