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.

诗人（部分有序的事件触发系统）是解决大型计算问题的一种显着不同的方式。传统计算机技术的演变使我们从具有少数字节的内存和（按照当今的标准）冰川时钟速度的简单机器中，转到了运行五个或六个数量级的多gabyte架构，但心中相同的基本过程：一次核心核心一次做一件事。在过去的几年中，架构似乎包含多个核心，但是在一般情况下，有效利用这些核心仍然是计算机科学的“圣杯”。POETS采用另一种方法，只有在今天才通过廉价，小型核心和庞大的可重新配置平台的扩散才成为可能。以前的EPSRC项目Bimpa使我们能够组装一百万个核心机器，从而创建了一种“元计算机”。在这里，程序员在这里定义了一组相对较小的，简单的行为，而不是明确编程每个核心的行为以及它们之间的每个沟通，而是为一组核心定义了一组相对较小的，简单的行为，并使其继续进行，并使它们保持正确的行为定义 - 系统的“自我验证”可以生成所需的构图，以实现范围的构造。替代性（基于物理）的问题，我们已经证明，这种方法可以导致速度急剧提高，而不是常规的解决方案技术。Poets并不是一种通用的计算技术，但是它非常适合各种传统上适合各种各样的强度工程和研究问题，在范围内，它可以在范围内启动的范围来验证的范围越来越及常规机器，以验证了这种成本的范围。结构是最好的（最快）？如何将它们自动配置为自组织？我们如何在这项新技术和新生的用户群之间建造桥梁？多年来，行业在计算技术方面进行了大量投资，如果诗人成为我们认为具有能力的破坏性技术，我们需要解决严重的“心灵”问题，以便商业吸收。
