Performance Profiling of Talbot Suite with TAU Analysis Tools, Part2: MPI Functions

This report describes the second part of the performance analysis of Talbot Suite by means of TAU (Tuning and Analysis Utilities) tools. Talbot Suite is a parallel software collection developed by the authors for the numerical inversion of Laplace Transform on recent advanced architectures. Talbot Suite deals with both single and multi-point inversion problems and collects Open MP functions for shared memory machines and MPI functions for distributed memory one. It integrates a first version of a hybrid implementation too. This report presents only performance measurements of the MPI functions on a specific architecture: a Blade Server.
