Kumar,
that means this device is not know by your Open MPI lib, so i
strongly encourage you to upgrade to the latest stable Open MPI 2.0.2
if you will not do that, here is the definition from the .ini file from
master
[Mellanox ConnectX5]
vendor_id = 0x2c9,0x5ad,0x66a,0x8f1,0x1708,0x03ba,0x15b3,0x119f
vendor_part_id = 4119
use_eager_rdma = 1
mtu = 4096
max_inline_data = 256
you can try to manually add it to
/.../share/openmpi/mca-btl-openib-device-params.ini
or add it to an other file and
mpirun --mca btl_openib_device_param_files
/.../my-openib-device-params.ini ...
Cheers,
Gilles

Thank you,

WARNING: No preset parameters were found for the device that Open MPI
detected:
Local host: n001
Device name: mlx5_0
Device vendor ID: 0x02c9
Device vendor part ID: 4119
Default device parameters will be used, which may result in lower
performance. You can edit any of the files specified by the
btl_openib_device_param_files MCA parameter to set values for your
device.
NOTE: You can turn off this warning by setting the MCA parameter
btl_openib_warn_no_device_params_found to 0.
