[GRASS-user] Parallel GRASS jobs .....

[Andranik Hayrapetyan]

I have been trying something like this some time ago, but I could not
define region of a mapset as chunk of the whole region.
I was trying to do that with g.region, but it only resized my map and
didn't "cut" it.

Is g.region the right tool for this task?
If it is not difficult for you, can you, please, explain the process of
 doing  " *define the region of each mapset as a chunk of the whole region* "
a bit more detailed.
