I have been testing the in-core version of this without the blocking and the results have been very impressive. On Tue, Apr 13, 2010 at 10:14 AM, Dmitriy Lyubimov wrote: > I see . to minimize loss of orthogonality. Brilliant. > > On Tue, Apr 13, 2010 at 9:41 AM, Ted Dunning > wrote: > > > What y

What you are suggesting is close to what I am doing. There are two differences, 1) the number of rows does depend on k+p, but not directly. The number of rows should be as large as practical to make the operations more efficient. 2) Oops. You are right. The columns will need to be renormalize

Why can't we say s=(k+p) and accumulate (k+p) x (k+p) A*Omega rows at one time in the mapper and make sure we orthogonalize (k+p) rows of Q in one block (by running a stock QR)? That way orthogonalization of the final Q will be quaranteed (although columns of Q would be scaled at approx [m/(k+p)] )

I am interested in contributing. The next two weeks will be a little busy, as it is end of term, but I would be more than happy to work over the summer on this project. Perhaps you can also give me some advice on how to accomplish a few tasks. Currently I am using NLineInputFormat to create/config
