You may have mentioned this in a prior mail, but what version are you using?
I tested and am unable to replicate your problem -- my openmpi-mca-params.conf
file is always read.
Double check the value of your mca_param_files MCA parameter:
shell$ ompi_info --param mca param_files
Mine comes out
Setting the orte_default_hostfile param in
*$HOME/.openmpi/mca-params.conf*
works (with $HOME set, of course), but for some reason setting it in the
system conf file,
*$prefix/etc/openmpi-mca-params.conf*
does not. Using 'ompi_info --param ...', it appear that the the system

The easiest solution is to take advantage of the fact that the default hostfile

cmd line. It can be in your environment, in the default MCA parameter file, or
in an MCA param file in your home directory.

This isn't the most straightforward solution, but as a workaround, create a
bash script and run that script through npRmpi? Something like:
!#/bin/bash
openmpi -np 15 -hostfile /path/to/hostfile $1

There have been many postings about openmpi-default-hostfile on the
list, but I haven't found one that answers my question, so I hope you
won't mind one more.
When I use mpirun, openmpi-default-hostfile does not appear to get used.
I've added three lines to the default host file:
