Yeah so the HCA querying/selecting will be good to have separate, as

establishment stuff.

Ha,.

Which reminds me, can we rename the OpenIB BTL to 'ofrc' as discussed on a call a long time ago? I will do the work if it's cool with everyone.

Can we wait until we bring the common/of stuff back from the tmp branch? It'll make the changes to the openib BTL significantly easier to merge.

I don't know Torsten's/Gleb's timeframe for moving everything to common/of -- my job was to provide the skeleton and I did so. :-)

Do we care about backwards compatibility of the openib name? I might
need help doing that, but shouldn't be a big deal.

Yes, I very much care about backward compatibility of the openib name and MCA parameters... This is, as I see it, the biggest issue with changing the name. Stuff like this has to work:

        mpirun --mca btl openib,self ...
        mpirun --mca btl_openib_foo 32 ...
