Designing and Evaluating MPI-2 Dynamic Process Management Support for InfiniBand

Free registration required

Executive Summary

Dynamic process management is a feature of MPI-2 that allows an MPI process to create new processes and manage communication with these processes. The dynamic creation of processes allows application writers to develop multiscale applications or master/worker based programs. Although several MPI implementations support this feature the authors are not aware of any studies on the issues in designing the dynamic process management interface and benchmarking of dynamic process framework. In this paper they design a MPI-2 dynamic process management interface over InfiniBand.
