If each simulated "neuron" is just a linear threshold unit, as described by the paper, using a whole process to run it and exchange messages by UDP looks like a terribly wasteful architecture.
Maybe the author wants to eventually implement a computationally expensive biologically accurate neuron model, but still I don't see the point of this architecture, as even if the individual neurons were biologically accurate, the overall simulation wouldn't, due to the non-deterministc delays and packet lossess introduced by UDP messaging.

I'm unimpressed.
