An efficient parallel algorithm for Lagrange interpolation and its performance

This paper introduces a parallel algorithm for computing an N=n2/sup n/ point Lagrange interpolation on n-dimensional cube-connected cycles (CCC/sub n/). The algorithm exploits several communication techniques in a novel way which can be adapted for computing similar functions. The performance of the algorithm is also evaluated by means of a speedup measure. It shows a near to optimal speedup for a state-of-the-art implementation technology.
