It's kind of characterizing the dynamics of virus spreading in arbitrary networks. It uses Markov knowledge.
There are a lot of complicated mathmatics equations.

Thanks. My mistake.
The os is 32-bit. I am doing a network-simulation for my teacher. The average degree of the network topology is about 6.0. So I think it is sparse.
The paper needs the eigen values and the eigen vectors which are necessary for the further simulation. I use the following procedure:
1. read the network vertices information from a txt file to a 10,000*10,000 list 'lists'.
2. And then use numpy.array(lits, dtype=float) to get a array object 'A'
3. Finally, use numpy.linalg.eig(A) to get the eigen values and eigen vectors.
4. Using 'tofile' function to write them to local file.
I will refer to scipy.
So is this some sort of Markov simulation with the messages passing between nodes with a given probability?
