Detailed Description

template<class LocalOrdinal, class Scalar>
class TSQR::TBB::RevealRankTask< LocalOrdinal, Scalar >

TBB task for recursive TSQR "rank-revealing" phase.

This part of the factorization doesn't actually reveal the rank in parallel; we assume that this has already been done and the columns of U form a basis for the column space of the R factor (in the QR factorization of the original matrix). All we need to do here is compute Q*U in parallel, respecting the original partitioning and cache blocking scheme.
