HI,<br>
Thanks for this.<br>
On a point of "note", don't you also wonder why people buy PCs with
slower CPU's <u>but more processing cores</u>, and then run
everything single-threaded :-)<br>
<br>
I do spatial data capture projects so am always scripting in
different environments and languages - so I write in a way that I
can run many (10+) scripts on 1 PC, and them still spread that
across sometimes even 10 PCs.<br>
<br>
(Nice to see that you are also 'production aware')<br>
<br>
Cheers for now,<br>
Zoltan<br>

processing into two parts — processing script for a single file
launched with "grass --exec python my_processing_script

launcher script starting multiple processing scripts in parallel (one
file = one mapset).
Afterwards it is easy to modify launcher script to be started by srun
or sbatch and migrate to more than one PC, when your tasks outgrows
single system resources.
Good luck,

Hi Zoltan,
did you try <a class="moz-txt-link-freetext" href="https://github.com/zarch/grass-session">https://github.com/zarch/grass-session</a>
That should simplify running GRASS algorithms using GRASS more as a library.
Cheers
Stefan

Emne: [GRASS-dev] PyCharm 2019 with Grass 7.8.1
Hi,
I've just installed QGIS/GRASS etc with Osgeo4w64, but am struggling to
find out how to set up PyCharm to do some grasspy scripting with.
(import grass.scripting as gscript fails - I have set GISBASE, GRASSBIN
and PATH to various C:\OSGeo4W64\apps\grass\grass78 folders)
I need to run r.thin over 2800 tif images, so figured a python loop
should do it.
Any pointers would be welcome.
Thanks and regards,
Zoltan
