    $\begingroup$ It would help if you were a bit more verbose on what exactly you mean with "non-negative", and what kinds of factorizations you are looking for. What do you happen to know about your matrix? $\endgroup$ Sep 3 '13 at 3:02

The following paper uses MapReduce for distributed computation of non-negative matrix factorization:

This paper describes an implementation and parallelization of the non-negative factorization and claims the results for matrices exceeding your specifications.

Regarding software libraries:
