Which architecture and OS did they wind up with? I was part of the team that went on to administer the Coral systems, which were linux on POWER 9+. Even the early-stage bringup loaders were linux systems. I remember they had to ship a couple x86 systems anyway, because Mellanox wouldn't make a POWER build of UFM. > Finally, why did something like this not ever happen?

I always thought NIX would have been a good fit for Xeon Phi MICs, since part of the bringup involved shipping an entire linux system to the card for booting anyway. Sadly, Intel (as usual) gave up on the architecture about ten minutes after release. We still have some sitting in a lab but I have a strict No Plan 9 At Work policy. The cards are cheap on ebay if anyone wants to investigate further. khm ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T7692a612f26c8ec5-M20294e9b8dea259d934e1005 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
