Which is the equivalent processing of human brain in terms of computer processing?

Question Detail: 

How many flops my brain can process, or how many GHz is a human brain capable of? Is it valid to think that each celular brain is like a small cpu? (like cuda architecture). Our brains works in parallel, right?

Here is what we know for sure. The largest neuronal network simulation to date was achieved using the K Japanese supercomputer (see the Top500) during summer 2013, a few months ago.

Using the open-source software NEST, the scientists simulated a network consisting of 1.73 billion nerve cells connected by 10.4 trillion synapses. To realize this feat, the program recruited 82,944 processors of the K Computer and used 1 petabyte of memory. The process took 40 minutes, to complete the simulation of 1 second of neuronal network activity in real, biological, time. Although the simulated network is huge, it only represents 1% of the neuronal network in the brain.

K is a peta-scale supercomputer, so, we need an exa-scale machine to completely simulate the whole human brain. These machines will be (probably) available between 2017-2020.
