The universe in which we live, everything we can touch, right down to the smallest components we can measure, is madeof matter. This may seem like an obvious statement, but at the beginning of the universe, we know that both matter, and itsmirror opposite antimatter were created in equal amounts. This raises the question: 'Where has all the antimatter gone?'In order to answer this and other fundamental questions about our universe, the fields of particle physics and astronomy are building some of the largest machines in the world. The Square Kilometer Array will be one of the largest and most precise telescopes, looking up at our universe, while the Large Hadron Collider and its HL-LHC upgrade will be the largest and most precise microscope, looking down at the smallest particles. Both of these machines need to process vast amounts of data, as quickly as it is produced, deciding which parts of the data are interesting to keep and which can be ignored. This is a major challenge, needing powerful computers to make decisions faster than ever before. The proposal develops new ways for these decisions to be made and monitored at the Square Kilometer Array and the Large Hadron Collider beauty experiment, to squeeze as much useful information as possible out of these machines in the hunt for new physics that reconciles particle physics and cosmology.

我们生活的宇宙，我们能接触到的一切，甚至是我们能测量到的最小的组成部分，都是由物质构成的。这似乎是一个显而易见的说法，但在宇宙诞生之初，我们知道物质及其镜像反物质都是等量产生的。这就提出了一个问题：“所有的反物质都去了哪里？”为了回答这个问题以及有关我们宇宙的其他基本问题，粒子物理学和天文学领域正在建造一些世界上最大的机器。平方公里阵列将是最大、最精确的望远镜之一，仰视我们的宇宙，而大型强子对撞机及其 HL-LHC 升级版将是最大、最精确的显微镜，俯视最小的粒子。这两台机器都需要在数据产生后立即处理大量数据，决定数据的哪些部分值得保留，哪些部分可以忽略。这是一项重大挑战，需要强大的计算机以比以往更快的速度做出决策。该提案开发了在平方公里阵列和大型强子对撞机美容实验中做出和监控这些决策的新方法，从这些机器中榨取尽可能多的有用信息，以寻找协调粒子物理学和宇宙学的新物理学。
