The OpenFabrics (openib) BTL failed to initialize while trying to
create an internal queue.  This typically indicates a failed
OpenFabrics installation, faulty hardware, or that Open MPI is
attempting to use a feature that is not supported on your hardware
(i.e., is a shared receive queue specified in the
btl_openib_receive_queues MCA parameter with a device that does not
support it?).  The failure occured here:


  Local host:  n026
  OMPI source: btl_openib.c:324
  Function:    ibv_create_srq()
  Error:       Success (errno=0)
  Device:      i40iw1


You may need to consult with your system administrator to get this
problem fixed.

WARNING: No preset parameters were found for the device that Open MPI
detected:


  Local host:            xxx
  Device name:           i40iw0
  Device vendor ID:      0x8086
  Device vendor part ID: 14289


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.

The OpenFabrics (openib) BTL failed to initialize while trying to
allocate some locked memory.  This typically can indicate that the
memlock limits are set too low.  For most HPC installations, the
memlock limits should be set to "unlimited".  The failure occured
here:


  Local host:    n026
  OMPI source:   btl_openib.c:794
  Function:      ompi_free_list_init_ex_new()
  Device:        i40iw1
  Memlock limit: 65536


You may need to consult with your system administrator to get this
problem fixed.  This FAQ entry on the Open MPI web site may also be
