Description

The Open MPI Project is an open source Message Passing Interface implementation that is developed and maintained by a consortium of academic, research, and industry partners. Open MPI is therefore able to combine the expertise, technologies, and resources from all across the High Performance Computing community in order to build the best MPI library available.

Available versions (Euler, old software stack)

Legacy versions	Supported versions	New versions
1.4.5	1.6.5	1.10.0, 1.10.2, 1.10.3, 1.8.0, 2.0.0, 2.0.2

Please note that this page refers to installations from the old software stack. There are two software stacks on Euler. Newer versions of software are found in the new software stack.

Environment modules (Euler, old software stack)

The open_mpi module is a smart module, which checks for a loaded compiler module and then loads the corresponding OpenMPI version. For the module load command example, we use the standard compiler gcc/4.8.2.

Version	Module load command	Additional modules loaded automatically
1.4.5	module load legacy gcc/4.8.2 open_mpi/1.4.5
1.6.5	module load gcc/4.8.2 open_mpi/1.6.5
1.10.0	module load new gcc/4.8.2 open_mpi/1.10.0
1.10.2	module load new gcc/4.8.2 open_mpi/1.10.2
1.10.3	module load new gcc/4.8.2 open_mpi/1.10.3
1.8.0	module load new gcc/4.8.2 open_mpi/1.8.0
2.0.0	module load new gcc/4.8.2 open_mpi/2.0.0
