1 - Find a faster CPU machine with 16Gb RAM and a SSD for a start, it will be better, Also if you have the opportunity check that the RAM is a 1800MHz one, details like this may actually add your computation performance. 2 - Cut in pieces (See Markus Comment about supercomputing) and run 4 quads

Hi, [snip] Be aware that you must use Python objects to transfer the data from the child process to its parent process using a queue[5]. I think that numpy array objects should work. I just realized that you can use shared ctypes objects as well for inter process communication[1]. [1]
