## OpenMPI
_Open MPI_ comes in many flavours with many combinations of underlying
transport libraries and running on many different fabrics. A complete
description of all combinations is beyond the scope of this guide.
On Mellanox hardware, we have had success running version 4.0 with the
UCX layer version 1.6 and using the following settings:
```
-mca coll_hcoll_enable 0
UCX_TLS=ud_x,shm,self
UCX_RC_MLX5_TM_ENABLE=n
UCX_DC_MLX5_TM_ENABLE=n
```
