Subject: [GRASS-user] 64 bit Python in GRASS 6.4.2


Hello all,

I've been working on a r.cost and r.drain python script that is using very
large rasters. I've been running into some memory issues with this script
due to the size of the rasters. I read about setting the amount of memory
that the map can be stored in with the "percent_memory=xx" argument for
r.cost, however the performance of running the script is becoming a problem
(it takes too long to run for our goal). 


I then started watching the Task Manager and noticed it was peaked out at
less ~4 gigs of ram and I realized it's only a 32 bit version of Python
installed with GRASS.

My question is: is there a compatible 64 bit version of Python for GRASS
6.4.x, and if so, how does one install it?


Thanks for your help!
