Computer systems today are all built around what is called the von Neumann architecture where the computation subsystem and the memory subsystem are separately designed and considered. This model has served the industry well for several decades. It does, however, create a bottleneck (referred as the von Neumann bottleneck) between the two subsystems. The increasing scale and dependence on data in modern computers put more and more stress on the von Neumann bottleneck, limiting computer speed and increasing energy costs. New technologies to address this problem can significantly improve all computers including modern data centers and supercomputers that are shouldering ever more responsibilities in science, medicine, engineering, business and commerce, and everyday life of an average citizen. This project is an effort to develop one such technology.The research centers around a novel nano-scale device recently developed by one of the investigators of the project. The device is called a coupled-disk resonator or CDR for short. CDR contains two flat disks very closely placed together. The fascinating property is that, thanks to technology, these disks can be shrunk down to nano-scale and placed in close proximity precisely. As a result, they can interact with light in a variety of controllable ways that allow computer designers to build superior optical communication systems than possible today. More excitingly, the CDRs can be manipulated to perform (simple) computations directly without having to convert optical signals first to electronic signals as is the case today. The potential outcome is not only high-performance communication channels, but smart ones that can significantly mitigate the von Neumann bottleneck. In this project, the investigators will study and experiment with the designs of both the device and the system built with these devices in an effort to bring this potential technology closer to reality.

当今的计算机系统都是围绕所谓的von Neumann架构建立的，在该体系结构中，计算子系统和内存子系统是单独设计和考虑的。该模型已经为该行业提供了好几十年。但是，它确实在两个子系统之间创建了一个瓶颈（称为von Neumann瓶颈）。现代计算机中对数据的规模不断提高，对冯·诺伊曼瓶颈（Von Neumann）瓶颈越来越压力，限制了计算机速度并增加了能源成本。解决此问题的新技术可以显着改善所有计算机，包括现代数据中心和超级计算机，这些计算机责任在科学，医学，工程，商业和商业以及普通公民的日常生活方面越来越多。该项目是为了开发这样的技术的努力。研究中心围绕一个新型的纳米级设备，该设备最近由该项目的研究者之一开发。该设备被称为耦合磁盘谐振器或简称CDR。 CDR包含两个非常紧密地放在一起的平盘。引人入胜的属性是，由于技术，这些磁盘可以缩小到纳米级，并恰好靠近近端。结果，他们可以以多种可控的方式与光进行交互，使计算机设计人员能够建立优越的光学通信系统。更令人兴奋的是，可以直接操纵CDR来执行（简单）计算，而无需像今天这样首先将光学信号转换为电子信号。潜在的结果不仅是高性能沟通渠道，而且还可以大大减轻von Neumann瓶颈的智能渠道。在这个项目中，调查人员将研究和尝试使用这些设备的设备和系统的设计，以使这种潜在的技术更接近现实。
