Efficient Parallelization of Lanczos Type Algorithms

Ilya Popovyan

Abstract: We propose a new parallelization technique for Lanczos type algorithms for solving large sparse linear systems over finite fields on mesh cluster architecture. The algorithm computation time scales as $P^{-1}$ on $P processors, and the communcation times scales as $P^{-1/2}$ for reasonable choice of $P$.
