  34. TSNNLS: A solver for large sparse least squares problems with non-negative variables
    Jason Cantarella and Michael Piatek.
    Unpublished (2004).
    arxiv:cs.MS/0408029
    tsnnls
    This unpublished manuscript describes the algorithm implemented in our open-source TSNNLS library. The library is used around the world for solving sparse constrained least squares problems of moderate size (matrices dimensions of a few thousand by a few thousand). TSNNLS was very fast for its day, but it is not an actively updated package and it is probably somewhat behind the times at this point. If you want to do more general or much larger problems of this type, I’d look at the COIN-OR project (specifically IpOPT).
