Abstract
In this paper we focus on Jacobi like resolution of the eigenproblem f or a real symmetric matrix from a parallel performance point of view: we try to optimize the algorithm working on the communication intensiv e part of the code. We discuss several parallel implementations and pr opose an implementation which overlaps the communications by the compu tations to reach a better efficiency. We show that the overlapping imp lementation can lead to significant improvements. We conclude by prese nting our future work.
