### Abstract

Most current multicomputers employ k- ary n-cube networks for lowlatency and high-bandwidth inter-processor communication. This paper introduces a parallel algorithm for computing an N=k^{n} point Lagrange interpolation on these networks. The algorithm consists of three phases: initialisation, main and final. While there is no computation in the initialisation phase, the main phase is composed of k^{n}/2 steps, each consisting of four multiplications and four subtractions, and an additional step including one division and one multiplication. The final phase is carried out in n×⌈k/2⌉ steps, each using one addition.
