It appears to be for the Myricom LanAI processor, which is available to others.  It&#x27;s an older 32 bit RISC processor, used as the offload engine for their NIC cards.<p>Here&#x27;s gcc for it: <a href="https:&#x2F;&#x2F;github.com&#x2F;myri&#x2F;lanai-gcc" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;myri&#x2F;lanai-gcc</a><p>Sounds like it&#x27;s not particularly interesting unless you want to write your own network offload code.<p>Edit: Probably just the offload processor they are choosing for their in-house routers&#x2F;switches&#x2F;servers.  And, probably they want their own firmware either for security&#x2F;nsa reasons, or performance, or both.
