Abstract
In this paper performance analysis of a parallel Levinson­type algorithm for Toeplitz
matrices is given. A modified version of the parallel algorithm is presented to improve
performance. The algorithm is implemented on a shared­memory MIMD (non­vector)
machine. The derivation of the parallel algorithm is presented. The speedup limitation
is investigated along with the optimal number of processors needed to a given Toeplitz
