[GRASS-user] r.patch.many with GRASS 7 b3?

GRASS GRASS user

Greetings,

I noticed that Hamish’s r.patch.many script is absent in the GRASS 7.0b3 repository.

I took a look at the script and it just runs r.patch in the background for the number for cores set, so it seems like it should be fine with GRASS 7, but if someone could confirm that I would appreciate it.

Thanks,

Just by looking at it, it probably should run. If you run it on beta3,

you'll be fine, with newer versions, g.mlist and g.remove were merged into
g.list and g.remove, so just remove the 'm' and it should work.

Great, thanks for the information!

I sure wish there was a similar script for r.in.proj - I am currently reprojecting 40,000+ tiles on 6-core machine, with 5 cores sitting idle.

:wink:

That should be pretty simple, simpler than r.patch.many, you just run a
certain number of r.proj processes in the background, wait and launch next
processes. There is a wiki
http://grasswiki.osgeo.org/wiki/Parallel_GRASS_jobs but perhaps someone has
already a simple template in bash you could use.

:wink:

Wow - thank you so much! I almost didn’t even mention it - but now I have all 6 cores lit up!!!
