Data-centric applications, from scientific simulation to emerging machine learning and data mining algorithms, are becoming prevalent. Memory-centric computing is a potential solution to overcome the unprecedented memory performance bottleneck for such applications. We propose an integrated, full-stack, cross-layer system to enable Unified Memory-centric Computing (UniMCC). We target systems that have near-memory data processors (NDPs) as well as a disaggregated shared memory pool. We work on the entire system stack to utilize these newly proposed hardware solutions from a unified viewpoint of architecture, SW/HW interface, code generation and runtime support, and performance modeling and optimization. The goal of the proposed UniMCC system is to maximize the potential of NDPs and disaggregated memories and lift memory-centric computing to a new level. The outcomes of the project will have significant broader impacts on research communities, society, and education. With the cross-layer collaborative design, the proposed research can bring state-of-the-art techniques together to make the memory-centric paradigm more feasible. The success of the project will enable experiments and deployment of data-centric applications at larger scales, facilitating research in the AI area and improving the availability of large-scale data mining and machine learning systems for solving real-world problems. Besides training Ph.D. students, this project will deliver several course developments, curricular update activities, and outreach activities to broaden participation in computing.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.

以数据为中心的应用程序，从科学模拟到新兴的机器学习和数据挖掘算法，正在变得越来越普遍。以存储器为中心的计算是一个潜在的解决方案，以克服前所未有的内存性能瓶颈，这样的应用程序。我们提出了一个集成的，全栈的，跨层的系统，使统一的内存为中心的计算（UniMCC）。我们的目标系统具有近内存数据处理器（NDP）以及分散的共享内存池。我们在整个系统堆栈上工作，从架构、SW/HW接口、代码生成和运行时支持以及性能建模和优化的统一角度利用这些新提出的硬件解决方案。所提出的UniMCC系统的目标是最大限度地发挥NDP和分散存储器的潜力，并将以存储器为中心的计算提升到一个新的水平。该项目的成果将对研究界、社会和教育产生更广泛的影响。借由跨层的协同设计，本研究可将最先进的技术整合在一起，使以记忆为中心的设计模式更具可行性。该项目的成功将使以数据为中心的应用程序的实验和部署能够在更大的规模上进行，促进人工智能领域的研究，并提高大规模数据挖掘和机器学习系统的可用性，以解决现实世界的问题。除了培养博士该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
