As the log shows: device mlx5_0 port 1 is not valid (port is used by SM)
Does it mean that if the mlx5_0 is used by SM, it will not be used by SHARP at the same time?
I filtered the mlx5_0 using NCCL_IB_HCA, then the error logs disappeared.
I have learned the issue: #320
Is my understanding correct?
