We'll have to let Intel speak to their roadmap, but they have publicly stated that the goal is to move libfabric to be a "native" provider for PSM2 / OmniPath (I'm not sure if they intend to do so for PSM / TrueScale?). I.e., the first implementation over PSM and PSM2 is a stepping stone towards the ultimate solution. Cray is also implementing a uGNI provider for their networks. Basically: libfabric is the next-generation API for all manner of networks (vs. the verbs API, which is strongly tied to InfiniBand hardware and wire protocol abstractions, which is why all of us fled verbs -- because we don't all sell IB hardware -- and went to libfabric). -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
