A Parallel Jacobi Diagonalization Algorthm for a Loop Multiple Processor System

Abstract

A parallel algorithm for the solution of the eigen-value problem by the Jacobi method is described. At each step of the algorithm, n/2 off-diagonal elements of the n xn matrix are annihilated simultaneously. Furthermore, because of the regular pattern of interprocessor communication, this algorithm is suitable for efficient implementation on a simple loop multiple processor system.
