Why does gdal use only one core?












11















I run gdal2tiles on debian machine with 4 cores:



sudo /usr/bin/gdal2tiles.py -r cubic -a 0,0,0 -z 10-15 /home/adm/topo/ekb.vrt  /var/www/tiles


In htop I see:

Why does gdal use only one core in work?
Gdal version is 2.1.2.

          That's because gdal2tiles is single-threaded. You can use a parallelized version available at https://github.com/GitHubRGI/geopackage-python/blob/master/Tiling/gdal2tiles_parallel.py

            There is another version of this file which include enhancements in different forks. Look at github.com/roblabs/gdal2tilesp/blob/master/gdal2tilesp.py (which is already a fork)
