ib_iface.c is not an SU2 file. It may be from ParMetis, what case are you running?

it's turb_ONERAM6.cfg, and the following is my script. I can run it with mpirun -n 2 SU2_CFD and -n 1 SU2, but it can't works more than 2. It's my first time using SU2.

seems to be a file from UCX, so it's a virtual machine issue I think? If you run SU2 from inside a virtual machine, you have to make sure that the vm has access to more than 2 nodes.
