MPI-Start and MPI-Utils

Abstract

mpi-start is a set of scripts to close the gap between the workload management system of a Grid insfrastructure and the configuration of the nodes on which MPI applications are run. The package is used to help the user to start MPI applications on heterogeneous Grid sites. mpi-start provides an abstraction layer that offers a unique interface to start parallel jobs with different execution environments implementations. It supports several different MPI implementations under different batch systems. mpi-start was originally developed in the frame of the int.eu.grid project for the execution of MPI applications with the CrossBroker metascheduler and then extended its use as the official way of starting MPI jobs within EGEE. Currently, it is part of the EMI project. There is a trac page at http://devel.ifca.es/mpi-start with information about the development of mpi-start.
