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! -Andy
