Thank you Vero. The last link is very interesting. But nothing about python run_command() with r.mapcalc Regards, Frank Le 16/09/2022 à 13:58, Veronica Andreo a écrit : Hi Frank, While not an expert here, did you see this other wiki: https://grasswiki.osgeo.org/wiki/Parallel_GRASS_jobs or Anna's presentation at FOSS4G 2022: https://htmlpreview.github.io/?https://github.com/petrasovaa/FUTURES-CONUS-talk/blob/main/foss4g2022.html#/ ?

Hello, Is there a way to parallelize r.mapcalc in python scripts with start_command() as it is with other command ? https://grasswiki.osgeo.org/wiki/Parallelizing_Scripts It seems to me r.mapcalc.tiled is not using processors at 100% Thank you Regards, Frank ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
