[GRASS-dev] r.sun and definition of numpartitions?

Hi,

I am planning to calculate energy maps based on a high res
DEM (458890698 cells, FCELL type). I'll use a multi-core
computer with several GB of RAM in a cluster environment.

How should I calculate the "numpartitions"? What is the expected
memory demand? I have to tell the job scheduler how much
memory I need for each process - I want to calculate daily
energy maps, so submit each day to a node of the cluster.

Hints appreciated,
Markus
