Abstract

THIS PAPER INTRODUCES A NEW PARALLEL QR FACTORIZATION WITH THE MODEST NUMBER OF PROCESSORS WHICH IS BASED ON BLOCK HOUSEHOLDER TRANSFORMATION. THIS ALGORITHM PERFORMS PARALLEL QR FACTORIZATION TO SPECIFIC BLOCKS OF SMALLER SIZE THAN THOSE OF THE INITIAL MATRIX, CAUSING AN IMPORTANT REDUCTION TO THE COMPUTATIONS.
