Artificial Brain and cryptanalysis

Was reading about different Blue brain or Artificial brain projects and thought of writing a simple network myself. So all I could afford myself is one compute machine from amazon which allows to run 3000 threads only if I am not doing much in each neuron. Each thread is a neuron and after adding little logic of filtering I came down to much lower number. I felt like, what am I doing, so to simulate this in cloud framework, I need the following,

  • A good messaging platform
  • A very lightweight service framework to make it work as neuron

And to able to use this network for doing a cryptanalysis is not far but the brain I produced is a size of an ant or less. I need bigger brain means a lot of machines => a lot of money ??
