Hej...
I am just trying to work out how to parallelize a simple Grassgis process in
python via the thread module. Is that generally possible?
Lets say I have a linefeature I want to transform into a raster with follwing
python command, where "n" should be 1,2 and 3 and the calculations should
happen in parallel mode.
I am thinking about following first approach:
def main(n):
grass.run_command("v.to.rast",
input = "line",
output = "line_raster",
use = "val",
value = n)
return 0
if __name__ == "__main__":
options, flags = grass.parser()
sys.exit(main())
thread.start_new_thread(main, (1,))
thread.start_new_thread(main, (2,))
thread.start_new_thread(main, (3,))
Has anyone worked already with parallelization in Python in combination with
GRASS GIS? How can a script look like for my purpose? I want to run the script
from outside grass. Maybe someone can tell how to proceed....
thank you
Johannes
