[GRASS-user] Hardware requirements to run GRASS

[Luí­s Moreira de Sousa]

I am getting old. The most recent 16-bit CPU released by Intel was the 80286 (I though all the x86 family were so). In the early 1990s we had two of these at Highschool - the first computers I ever used to do something other than playing games.

These old processors could only address 16 MB of RAM, therefore we can easily exclude them from the list of supported hardware.

Cheers.

The nice thing about GRASS GIS (and I think that not many other software
packages have this), however, that many modules can be run using low RAM
as well (see the raster modules with the memory option and the
GRASS_VECTOR_LOWMEM environment variable). This allows to run complex
analyses on large datasets with low levels of RAM. You just have to be
ready to wait ;-)
