    • Sparse Givens QR Factorization on a Multiprocessor 

      Touriño, Juan; Doallo Biempica, Ramón; Zapata, E.L. (IEEE Computer Society, 1996-06-01)
      [Abstract] We present a parallel algorithm for the QR factorization with column pivoting of a sparse matrix by means of Givens rotations. Nonzero elements of the matrix M to be decomposed are stored in a one dimensional ...
