The Computer Designed To Die In Microseconds

推荐理由

Politely, this computer exists because the DoE performs stockpile stewardship. Less politely, it exists because of The Bombs. Everything else it will do is a hobby. It is specifically designed for whatever compute needs their classified program has. [LINK] [LINK] All of this capital is being spent because the test ban treaty prohibits the detonation of these weapons, but the US stockpile and its efficacy must be maintained and new weapons must be designed. So how do you know if an old weapon or a new design will work or not? Some part of the answer is real data + simulations. Lots and lots of simulations. It's why Frontier exists and why the DoE has pursued exascale compute for quite some time. (as for the real data part, it's why places like the National Ignition Factory exist, and why there's an active experimental program that exists to study dummy warheads in unexpected ways, [VIDEO] )

说明

这是2023年由Scott Manley发布的一部讲解,主题归在Military history & warfare。它讲的是nuclear weapons testing这一支里的具体问题,而不是把整个领域扫一遍。适合按兴趣直接看、不打算先补课的人。内容上可以概括成:Scott Manley tells the story of a computerized telemetry system built to sit at the heart of a nuclear test device in place of the plutonium pit, designed to transmit data in the microseconds before it was destroyed.这些读者给出的理由,核心是:HN mentions it only in passing, as a reference for instrumented dummy warheads and implosion-test data in nuclear-testing threads.讲法不绑某一条新闻,过几年仍然可以当材料看。从2023年到2025年,有0位不同的读者在0个不同月份把它推荐出来,其中明确叫别人去看的有0次。适合用一集把一个概念补上的人。抓住它用的那个图像或类比,比背公式重要。如果已经会了基本定义,就把注意力放在它怎么把nuclear weapons testing变成能跟着复述的例子。
