Cloud data centers are a vital piece of technology infrastructure today. Applications and websites rely deeply on their efficient operation to serve millions to billions of users. To improve the useful utilization of cloud servers and ease application development, cloud platforms have recently developed a new design paradigm known as serverless computing. New serverless applications are made of very small pieces of code, which often run for just milliseconds, in contrast to traditional applications. This research project investigates the implications of this change on microprocessors which have been historically designed for long-running applications. The project explores how to modify the cores of the microprocessor to improve their energy efficiency when running such serverless applications. Improving the efficiency of serverless computing in cloud data centers will enable cost savings and a reduced environmental footprint across economic sectors while lowering the barrier to entry for new entrants with novel applications. In addition, this project integrates an education plan featuring a new change of major pipeline and participation in equitable and inclusive teaching practices workshops to broadly enhance the diversity of the growing cloud computing and computer science workforce.This project investigates the impacts of emerging, short-lived applications like serverless computing on the prediction structures embedded into microprocessors designed with long-lived applications in mind. Serverless applications waste significant energy and time running on today's server processors, but they have been adopted to improve overall server utilization and developer productivity. Saving the contents, or microarchitectural checkpointing, of structures like branch predictors and caches thus has the potential to drastically improve the efficiency of serverless and supercharge traditional applications by eliminating microarchitectural training time. This project investigates which structures are best to checkpoint, implements checkpointing mechanisms into commercially-adopted, open-source processors, designs the user and operating system software interfaces to the programmer, and proposes new security protections needed to make the checkpointing adoptable. This full-stack prototyping process, exploiting real-world, open-source software and hardware, will demonstrate the significant efficiency benefits realizable with microarchitectural checkpointing. This will enable more efficient data centers for serverless edge and cloud computing that are proliferating as well as traditional, long-running applications, all of which underpin the cloud services that society relies on.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

云数据中心是当今技术基础架构的重要组件。应用程序和网站深处依靠其有效的操作来为数十亿用户提供数百万美元的服务。为了改善云服务器的有用利用并轻松应用程序开发，云平台最近开发了一种称为无服务器计算的新设计范式。新的无服务器应用程序是由非常小的代码制成的，与传统应用相比，通常仅用于毫秒。该研究项目调查了这种变化对历史上专为长期应用设计的微处理器的含义。该项目探讨了如何修改微处理器的内核，以在运行此类无服务器应用程序时提高其能源效率。提高云数据中心中无服务器计算的效率将促进成本节省，并降低经济领域的环境足迹，同时降低具有新颖应用的新进入者的进入障碍。此外，该项目还整合了一项教育计划，该计划的新管道发生了新的变化，并参与了公平和包容的教学实践讲习班，以广泛增强不断增长的云计算和计算机科学劳动力的多样性。该项目调查了新兴的，短暂的，短暂的应用程序的影响，例如无用的计算在预测结构中，将其用于小型生产商的应用程序中的高级应用程序，该应用程序的效果为小型生产商而设计。无服务器的应用程序浪费了当今服务器处理器上的大量精力和时间，但是已采用它们来提高服务器的利用率和开发人员的生产率。因此，保存分支预测指标和缓存等结构的内容或微体系检查点，因此有可能通过消除微实施式培训时间来大大提高无服务器和增压传统应用程序的效率。该项目调查了哪些结构最适合检查点，将检查点机制实现到商业化的开源处理器中，将用户和操作系统软件接口设计给程序员，并提出了使检查点可采用的新安全保护。这种全栈原型制作过程，利用现实世界，开源软件和硬件，将证明使用微构造检查点可实现的显着效率优势。这将使更有效的数据中心用于无服务器的边缘和云计算以及传统的，长期运行的应用程序，所有这些应用程序都是社会所依赖的云服务的所有基础。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来通过评估来支持的，这是值得的。
