Re: Page Ranking, Hadoop And MPI.

Hello, It was wonderful explanation about the role and beauty of eigenvalues in ranking. But I am still far from the real answer/hint. How Google handle such a large matrix and solve it ? Do they use MapReduce framework for these process or adopt standard and reliable Message Passing Interface
