Deep Neural Networks (DNNs) have become one of the most popular machine-learning techniques for solving real-world problems in object classification, autonomous vehicles, natural language processing, etc. Due to the ever-growing problem size and complexity, the training and inference of DNN models are increasingly time-consuming and require enormous computing resources. As such, multi-GPU infrastructure is a desirable platform that has been widely used in modern DNN tasks. However, the delivered DNN execution scalability is severely limited due to architectural unawareness and lacking easy-to-use runtime support. This research uncovers and addresses the architectural bottlenecks of DNN executions. The outcome of this research is expected to achieve scalable DNN executions on multi-GPU infrastructure. The educational and outreach components of this project include (i) new course projects on multi-GPU infrastructure integrated into graduate-level computer architecture courses; (ii) engaging undergraduate students in the research activities through senior Capstone project courses and an outreach program at PI’s institute; and (iii) increasing the participation and visibility of female and minority students in computer architecture, computer science, and engineering.This research is set to uncover and address the architectural bottlenecks of DNN executions on multi-GPUs. Specifically: 1) It identifies address translation as an essential bottleneck in multi-GPU performance. It redesigns the Translation Lookaside Buffer (TLB) hierarchy and the page table walk for both single-tenant and multi-tenant DNN executions on multi-GPU infrastructure. 2) It investigates the data-movement overheads in data parallelism and model parallelism of modern DNN applications. It proposes architecture-aware data distillation and neuron-based model partitioning to mitigate the data movement overheads. 3) It proposes a runtime framework that fosters the usage of multi-GPUs through enhanced programmability, which allows dynamic and automatic virtual kernel to physical kernel generation during execution.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.

深度神经网络(DNN)已经成为解决现实世界中对象分类、自主车辆、自然语言处理等问题的最常用的机器学习技术之一。由于问题的规模和复杂性不断增长，DNN模型的训练和推理越来越耗时，需要大量的计算资源。因此，多GPU基础设施是现代DNN任务中广泛使用的理想平台。然而，由于不了解体系结构和缺乏易于使用的运行时支持，交付的DNN执行可伸缩性受到严重限制。这项研究揭示并解决了DNN执行的体系结构瓶颈。这项研究的成果有望在多GPU基础设施上实现可扩展的DNN执行。该项目的教育和推广部分包括(I)将多图形处理器基础架构整合到研究生级别的计算机体系结构课程中的新课程项目；(Ii)通过高级Capstone项目课程和Pi学院的扩展计划吸引本科生参与研究活动；以及(Iii)提高女性和少数族裔学生在计算机架构、计算机科学和工程方面的参与度和知名度。这项研究旨在揭示和解决在多GPU上执行DNN的架构瓶颈。具体地说：1)指出地址转换是影响多GPU性能的重要瓶颈。它为多GPU基础设施上的单租户和多租户DNN执行重新设计了转换后备缓冲区(TLB)层次结构和页表遍历。2)研究了现代DNN应用的数据并行性和模型并行性中的数据移动开销。它提出了基于体系结构的数据提炼和基于神经元的模型划分来减少数据移动开销。3)它提出了一个运行时框架，通过增强的可编程性促进多GPU的使用，允许在执行过程中动态和自动生成虚拟内核到物理内核。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
