above sim is floating type.
s.append is totally coducted 60,494,500 times.

My computer has 4G RAM.
i think it's enough. but it doesn't...
Try creating it in a more clean way, here an array of doubles:
from array import array
a = array(d, [0.0]) *

Each time you are appending to the list, you append a tuple:
((i, j), sim)

those take?
sys.getsizeof( ((0, 1), 1.1) )
