#### Cautionary note for system openmpi
When using system openmpi, some caution is required due to the
[openmpi issue 5375](https://github.com/open-mpi/ompi/issues/5375) that
affected several versions of the openmpi2 or openmpi3 series.
| series | major/minor | Minimum version
|-----------|-------------|-------------------|
| openmpi1 | all | not affected |
| openmpi2 | 2.0 | avoid this series |
| openmpi2 | 2.1 | 2.1.6 |
| openmpi3 | 3.0 | 3.0.4 |
| openmpi3 | 3.1 | 3.1.4 |
