About the second (order of rows vs. columns), we have a problem that in distributed graphlab we
output the matrix by rows, since each node is a row, and nodes are on different machines.
So to be compatible I left GraphChi code to confirm to GraphLab. In case it helps, here is a matlab mmread.m
function which switches the order to be sorted by rows http://select.cs.cmu.edu/code/graphlab/mmread.m
I am not sure if it is easy to fix it in python or not. [...]
