There are several possibilities to make this option the default one.
The simplest one is to use the mca-params.conf file. In your home
directory create a .openmpi directory and inside create a file called
mca-params.conf. You can add in this file all options that you want
to be the default

Couple of things you might want to add:
1. RedStorm design - what are we going to do about the RTE?
2. Multi-cell RTE - I've been working on this (finally set it aside to
complete the scalable startup stuff first), but it is complex and might
merit some discussion with those interested.
Currently I have to set this environment variable on bproc/x86_64 or
mpirun just hangs. Would it be possible to make this the default
setting until it's fixed?

Thanks to Edgar for copying me on this: it sounds like I asked at the right
time. There were some OpenMP-internal discussions on this a couple of years
ago, and a straw proposal, but at that time there was no obvious interest
on the MPI side. So we'd have to go back and look at the ideas that came

Excellent. Seems like several people have thought of this at the same
time (I was pinged about this by the IB vendors).

To add to this, I would suggest not coupling processor affinity and
memory locality at the component level. At some level you do need
to tie these together, but there are other components that also need
to be considered, such as NIC locality, and probably other things
too ...
