Thanks Joe. Here is the output from the commands you suggested. We have open mpi built from Intel mpi compiler. Is there some benchmark code I can compile so that we are all comparing the same code?

[hussaif1@lustwzb4 test]$ ibv_devinfo
hca_id: mlx4_0
        transport:                      InfiniBand (0)
        fw_ver:                         2.11.550
        node_guid:                      f452:1403:0016:3b70
        sys_image_guid:                 f452:1403:0016:3b73
        vendor_id:                      0x02c9
        vendor_part_id:                 4099
        hw_ver:                         0x0
        board_id:                       DEL0A40000028
        phys_port_cnt:                  2
                port:   1
                        state:                  PORT_ACTIVE (4)

Port 1 on the machine is up. This is the link level activity that the subnet manager (OpenSM or a switch level version) enables.

For OpenMPI, my recollection is that they expect the IB ports to have ethernet addresses as well (and will switch to RDMA after initialization).

What does

    ifconfig -a

report?
