[GRASS-user] r.mapcalc multiprocess

[Lorenzo Bottaccioli]

Hi Stefan,

I have just updated my grass-gis version to 7.0.3, berfore I was using
7.0.0 version and mapcalc was running in multitheard mode and was much
faster. My question is how can i make it run again in multitheading?

Regards,

Lorenzo
