[GRASS-user] How does GRASS do tiled processing?

    I was curious -- how is tiled processing realized in GRASS GIS?  Is 
there a fixed input tile size (in MB of RAM or # of lines)?  Is there 
some documentation buried on the GRASS site that describes the 
algorithm?  I'm trying to replicate an efficient tiled approach in R -- 
I was basing it off the ENVI approach (precalculate the input data 
memory footprint per line of data, read in as many lines as the memory 
cap allows, process, write those lines, rinse, repeat), but I was 
curious if GRASS had a different approach.
