With the release of Knights Landing, the standalone CPU version on the
Xeon Phi, Intel is supposed to introduce Storm Lake, a 100Gb/s host
fabric interface, which could provide CPU to CPU interconnection
between nodes. It will probably be based on the QLogic and/or Cray IP
they acquired, or maybe not, details have been scarce, but those
cables just look like another piece of the puzzle.
