[GRASS-user] Hardware requirements to run GRASS

[Luí­s Moreira de Sousa]

Dear Rich, in general I agree with you. They also asked for my Fax number, this particular journal seems to be still in the XX century.

However, there are some basic clues I could give. For instance, can GRASS run on a 16-bit system? Or 8-bit? What is the minimum RAM required to launch the GRASS console?

Thank you.

Luís,

My immediate response is that this is a meaningless question; that is, one
asked out of ignorance of computers and software. The requirements really
depend on what types of analyses will be done with grass and how large are
the data sets that will be applied.

For example, most of the time I analyze spatial data on a 32-bit
Slackware-14.1 workstation with 2 cores and 4G RAM. But, for hydrological
modeling with DEM resulution of 1m x 1m over a ~40 ha area, I run the models
on a 64-bit Slackware-14.2 host with 4 cores (and no more than 2 cores per
process) with 8G RAM. The modeling time on the older host is excessive; on
the faster one runs could take up to 9 days.

HTH,

Rich
