problems using PSM2 "Trying to connect to a HFI (subnet id - 0)on a different subnet - 1023 "

hello,

I installed the Omni-path driver ( IntelOPA-Basic.RHEL74-x86_64.10.6.1.0.2.tgz ) on two identical KNL/F servers with Centos  ( CentOS Linux release 7.4.1708 (Core) )

I executed the MPI Benchmark provided by intel using PSM2:

mpirun -PSM2 -host 10.0.0.5 -n 1 /opt/intel/impi/2018.1.163/bin64/IMB-MPI1 Sendrecv : -host 10.0.0.6 -n 1 /opt/intel/impi/2018.1.163/bin64/IMB-MPI1 Sendrecv

And the execution return the following error:

[silvio@phi05 ~]$ mpirun -PSM2 -host 10.0.0.5 -n 1 /opt/intel/impi/2018.1.163/bin64/IMB-MPI1 Sendrecv : -host 10.0.0.6 -n 1 /opt/intel/impi/2018.1.163/bin64/IMB-MPI1 Sendrecv

I search this message on google (Trying to connect to a HFI (subnet id - 0)on a different subnet - 1023 ) and the only reference is the following source code:

https://github.com/01org/opa-psm2/blob/master/ptl_ips/ips_proto_connect.c

How do i put the two fabrics in the same subnet?

When i change to Infiniband it works:

mpirun -IB -host 10.0.0.5 -n 1 /opt/intel/impi/2018.1.163/bin64/IMB-MPI1 Sendrecv : -host 10.0.0.6 -n 1 /opt/intel/impi/2018.1.163/bin64/IMB-MPI1 Sendrecv
