There are different implementation for the MPI standart. The D-Grid reference installation consider the http://www.open-mpi.org/ Open MPI] (MPI-2 Implementation) project. To use the MPI for the Grid infrastructure, the MPI-Start is needed. MPI-Start is a set of shell 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. To use the MPI, the following hosts should be configured withing the cluster:
- grid middleware server (gLite CE 3.1)
