Re: [OMPI devel] IPv6 support in OpenMPI?

[Ralph Castain]

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.

In other words, the solution must support systems including computers that only know IPv4. It is clear to me that we cannot entirely rely on the availability of IPv6-mapped IPv4 addresses. Getting the IPv6-enabled sources to compile on systems without sockaddr_in6 or getaddrinfo() is sort of nasty, but should be possible. For example, we could extend the configure script to test this and provide some drop-in replacements in case these structures/call are missing on the system. Are there some reference platforms which are really old, but need to be supported? The information on slide 101 on http://www.open-rte.org/documentation/march-2006-orte/March-2006-ORTE.pdf is fairly generic... Christian
