A Journal editor is requesting the minimum hardware requirements to run GRASS. I found a 20 year old unsigned post [0] with some hints, but certainly things have changed since. Can anyone shed some light on modern requirements?
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.
