Re: [OMPI devel] IPv6 support in OpenMPI?

Actually, we have some sensor network folks that are interested in using OpenRTE for their applications. Their platforms can be small microprocessors, many with custom mini-operating systems. Almost none support IPv6 nor have any knowledge of that protocol. Ralph Christian Kauhaus wrote:

Hi folks Sorry to be coming late to the discussion - I'm on travel, so my comments will likely have long time delays in them. Only one contribution I would like to make. You are welcome to do whatever you like (subject to the usual approval procedure) in the MPI layer (the btl's for example)
