This short-term research project will address the challenge of achieving near PetaOps scale performance within a decade through innovative systems that exhibit wide applicability and ease of use. The objective of the proposed research is to determine the feasibility and detailed structure of a parallel architecture integrating the combined capabilities of semiconductor, superconductor, and optical technologies. This hybrid architecture approach is motivated by the realization that a mix of technologies may yield superior operational attributes to those possible based solely on semiconductor technology in the same time frame. An interdisciplinary team of collaborators has been assembled to conduct the required point-design study in order to devise a complete system structure and evaluate its performance characteristics using a small set of scientific application kernels. The proposed hybrid technology approach exploits critical opportunities enabled by key emerging devices. Specifically computational performance can be dramatically improved through recent advances in Superconducting Rapid Single Flux Quantum logic which will make 100 Ghz clock rates feasible in the next two years. Memory capacity may be drastically increased through a new memory hierarchy, merging advanced semiconductor high density memory and future (admittedly more speculative) optical 3-D holographic storage capable of storing 0.1 Petabits or more. Interconnection bandwidth will be greatly enhanced by means of optical networks with 100 Gbps channels.

这个短期研究项目将通过具有广泛适用性和易用性的创新系统，解决在十年内实现接近PetaOps规模性能的挑战。 拟议的研究的目的是确定的可行性和详细结构的并行架构集成的半导体，超导体和光学技术的综合能力。 这种混合架构方法的动机是认识到，在相同的时间范围内，技术的混合可以产生比仅基于半导体技术的那些可能的操作属性优越上级的操作属性。 一个跨学科的合作者团队已经组装进行所需的点设计研究，以设计一个完整的系统结构，并评估其性能特点，使用一套小的科学应用内核。 拟议的混合技术方法利用了关键新兴设备带来的关键机遇。 具体地说，通过超导快速单通量量子逻辑的最新进展，计算性能可以大大提高，这将使100 GHz的时钟速率在未来两年成为可能。 通过一种新的存储器层次结构，将先进的半导体高密度存储器和未来（公认更具投机性）能够存储0.1 Petbit或更多的光学3D全息存储器合并，可以大幅增加存储容量。 100 Gbps通道的光网络将大大提高互连带宽。
