Implementing Communication-Optimal Parallel and Sequential QR Factorizations
James Demmel, Laura Grigori, Mark Hoemmen +1
We present parallel and sequential dense QR factorization algorithms for tall and skinny matrices and general rectangular matrices that both minimize communication, and are as stab…
Communication-optimal parallel and sequential QR and LU factorizations
James Demmel, Laura Grigori, Mark Hoemmen +1
We present parallel and sequential dense QR factorization algorithms that are both optimal (up to polylogarithmic factors) in the amount of communication they perform, and just as…
