== What is mpi-start? ==

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 start MPI applications on heterogeneous Grid sites.

MPI-Start was originally developed in the frame of the [[http://www.i2g.eu/|int.eu.grid project]] for the execution of MPI applications with the [[http://devel.ifca.es/cb/ |CrossBroker metascheduler]] and then extended its use as the official way of starting MPI jobs within [[http://egee-eu.org/|EGEE]]. Currently, it is part of the [[http://www.eu-emi.eu/|EMI]] project.

Development info and code repo is available at github: https://github.com/IFCA/mpi-start (old tickets still available at http://devel.ifca.es/mpi-start)

== Get mpi-start ==

mpi-start was part of the [[http://www.eu-emi.eu/|EMI]] project. The packages can be still be obtained from the [[http://emisoft.web.cern.ch/emisoft/|EMI repository]].

Newer mpi-start versions are built with the openSUSE Build Service. A [[https://build.opensuse.org/package/show/home:enolfc/mpi-start|mpi-start project]] contains packages for the latest releases.

Source is available at [[https://github.com/IFCA/mpi-start|mpi-start github repository]].

== Software Requirements and Specifications ==

The [[/RequirementsAndDesign|Requirements and Design]] page presents the requirements specifications and a description of the MPI-Start implementation.

== User Documentation ==

MPI-Start documentation for final users can be found at [[/UserDocumentation|User Documentation]], you can check also the typical error list and solutions in the [[/TroubleshootingGuide|Troubleshooting Guide]].

== Developer Documentation ==

If you want to develop new plugins for MPI-Start, you can consult the [[/DeveloperDocumentation|Developer Documentation]].

== System Administrator Documentation ==

A guide for system administrators that install MPI-Start at the sites is at [[/SiteConfiguration| Site Configuration]]. gLite sites may use the [[/MpiUtils| MPI-utils]] package for an easier configuration of MPI support.

The [[/ServiceReferenceCard | service reference card]] contains additional information.

There are configuration examples in [[/ParallelEnvironment| EMI-ES ParallelEnvironment]] to set up MPI-Start as backend for the different EMI-ES implementations.

== More information ==

EGI provides also an [[https://wiki.egi.eu/wiki/MAN03_MPI-Start_Installation_and_Configuration | installation and configuration manual]].
