Early 2022 is only like 4-8 months away?
Aurora was supposed to be delivered in 2018: https://www.nextplatform.com/2018/07/27/end-of-the-line-for-... After it was delayed, Intel said that 2020 was when they'd be ready. Spoiler alert: they aren't: https://www.datacenterdynamics.com/en/news/doe-confirms-auro... We're now looking at 2022 as the new "deadline", but we know that Intel has enough clout to force a new deadline as necessary. They've already slipped…
Aurora was originally slated to use Phi chips, which are an unrelated architecture to these GPUs. The delays there don't say much about problems actually getting this new architecture out. It's more that they were halfway through making a supercomputer and then started over.
I could probably pin the biggest share of the blame on 10nm problems, which are irrelevant to this architecture.
As far as this architecture goes, when they announced Aurora was switching, they announced 2021. That schedule, looking four years out for a new architecture, has only had one delay of an extra 6 months.
