CPS: Small: Low-Impact Monitoring of Streaming Systems

本研究的目标是提高流媒体应用程序的性能和应用程序开发效率。该方法是使用架构上不同的计算引擎，例如现场可编程门阵列和图形处理单元，来执行应用程序的部分。这种方法特别适合于处理流数据的应用程序，例如来自望远镜或其他科学仪器等传感器阵列的数据。尽管在与物理世界交互的性能关键型系统中使用架构多样化的系统由来已久，但应用程序开发一直是一项挑战。该提案寻求通过在两个基本领域取得重大进展来改进应用程序开发：性能监控器和调试器。该方法具有以下特性：它对于被监视的应用程序是非侵入性的，并且它支持关于罕见事件的数据收集。特别是，它允许将应用程序的网络部分与发生罕见事件的物理部分相关联。对社会的影响：这项研究可以对从科学仪器到医学成像的网络物理计算应用产生巨大影响。能效、重量和体积的改进都可以通过使用架构多样性来实现。教育：拟议的研究将由研究生和本科生进行，这既是为了继续他们的教育，也是为了增加国家训练有素的劳动力。代表性不足的群体：华盛顿大学校长奖学金和奥林奖学金计划将被用来吸引来自代表性不足群体的个人参与。

The objective of this research is to enable improved performance and application development efficiency for streaming applications. The approach is to use architecturally diverse computing engines, such as field programmable gate arrays and graphics processing units, to execute portions of an application. This approach is especially well suited to applications that process streaming data, such as from a sensor array like a telescope or other scientific instrument.Intellectual merit. While the use of architecturally diverse systems has a long history in the world of performance-critical systems that interact with the physical world, application development has always been a challenge. This proposal seeks to improve application development by making significant progress in two essential areas: performance monitors and debuggers. The approach has the following properties: it is non-intrusive with respect to the application being monitored and it supports data collection concerning rare events. In particular, it allows correlation of the cyber portion of an application with the physical portion in which the rare events occur.Broader impacts. Impact on society: The research can have a dramatic impact on cyber-physical computing applications, from scientific instrumentation to medical imaging. Improvements in power efficiency, weight, and volume are all achievable through the use of architectural diversity. Education: The proposed research will be carried out by graduate and undergraduate students, both furthering their education and increasing the nation's trained workforce. Underrepresented groups: Washington University's Chancellor's Fellowship and Olin Fellowship programs will be leveraged to attract the participation of individuals from underrepresented groups.
