Comment (by mmetz):
Replying to [ticket:3104 belg4mit]:
> Currently QGIS will peg one of my cores while running r.cost. This
leaves the system usable, but it also greatly slows down the execution
time. Traversal of the cost raster should be readily parallelizable, and
could divide the run time by the number of cores allocated.
Can you provide hints about how r.cost could be parallelized? That would
help a lot.
