Several works on different methods and issues of root finding have been reported in~\cite{Azad07, Gemignani07, Kalantari08, Skachek08, Zhancall08, Zhuall08}. However, Durand-Kerner and Ehrlich-Aberth methods are the most practical choices among them~\cite{Bini04}.

With the advent of CUDA (Compute Unified Device Architecture), finding the roots of polynomials receives a new attention because of the new possibilities to solve higher degree polynomials in less time. In~\cite{Kahinall14} we already proposed the first implementation
