POETS (Partially Ordered Event Triggered Systems) is a significantly different way of approaching large, compute intensive problems. The evolution of traditional computer technology has taken us from simple machines with a handful of bytes of memory and (by the standards of today) glacial clock speeds, to multi-gigabyte architectures running five or six orders of magnitude faster, but with the same fundamental process at the heart: a central core doing one thing at a time. Over the past few years, architectures have appeared containing multiple cores, but exploiting these efficiently in the general case remains a 'holy grail' of computer science.POETS takes an alternative approach, made possible only today by the proliferation of cheap, small cores and massive reconfigurable platforms. A previous EPSRC project, BIMPA, enabled us to assemble a million core machine, creating a kind of 'meta-computer'. Rather than program explicitly the behaviour of each core and each communication between them, as is done in conventional supercomputers, here the programmer defines a set of relatively small, simple behaviours for the set of cores, and leaves them to get on with it - with the right behavioural definitions , the system 'self-organises' to produce the desired results.BIMPA was designed primarily for neuroscience applications, but a subsidiary research objective allowed us to study the use of the architecture for alternative (physics-based) problems, and we have demonstrated that this kind of approach can lead to dramatic speed increases over conventional solution techniques.POETS is not a general-purpose computing technique, but it is elegantly suited to a variety of traditionally compute intensive engineering and research problems, where it can produce results orders of magnitude faster than conventional machines at a fraction of the cost.The purpose of this research project is to explore this application arena: what kind of architectures are best (fastest)? How might they be automatically configured to self-organise? How might we build bridges between this new technology and a nascent user base? Industry has invested heavily - quite sensibly - in computing technology over the years, and if POETS is to become the disruptive technology we believe it to be capable of, we need to address a serious 'hearts and minds' issue for commercial uptake to ensue.

POETS（部分有序事件触发系统）是处理大型计算密集型问题的一种显著不同的方法。传统计算机技术的发展使我们从拥有少量内存和（按照今天的标准）冰川时钟速度的简单机器，发展到运行速度快五到六个数量级的多千兆字节架构，但核心是相同的基本过程：一个中央核心一次做一件事。在过去的几年里，出现了包含多个内核的架构，但在一般情况下有效地利用这些内核仍然是计算机科学的“圣杯”。POETS采取了另一种方法，直到今天，廉价的小内核和大规模可重构平台的激增才成为可能。EPSRC之前的一个项目BIMPA使我们能够组装一台百万核机器，创造一种“元计算机”。与传统的超级计算机不同的是，程序员不需要对每个内核的行为以及它们之间的通信进行明确的编程，而是为内核定义一组相对较小、简单的行为，然后让它们继续工作--通过正确的行为定义，系统“自我组织”以产生预期的结果。BIMPA主要为神经科学应用而设计，但一个附属的研究目标使我们能够研究建筑的用途，POETS不是一种通用的计算技术，但它非常适合于各种传统的计算密集型工程和研究问题，在那里，它可以产生的结果数量级比传统的机器更快，成本的一小部分。这个研究项目的目的是探索这个应用竞技场：什么样的架构是最好的（最快的）？它们如何被自动配置为自组织？我们如何在这项新技术和新生的用户群之间建立桥梁？多年来，工业界在计算技术上投入了大量资金，这是非常明智的，如果POETS要成为我们认为它能够实现的颠覆性技术，我们需要解决一个严重的“心灵和思想”问题，以便随后实现商业化。
