The authors parallelize an algorithm presented by \textit{M. J. Schaefer} [Interval Comput. 1993, No. 4, 22-39 (1993; Zbl 0829.65063)] for verifying zeros of analytic functions in the complex plane. This algorithm is based on a bisection strategy, the winding number and Newton's method. Parallelism is introduced into the original serial method at four levels. A numerical example is computed on a workstation cluster and is discussed in detail. An overview of DTS (Distributed Thread System) concludes the paper.
