SDCC: software-defined collective communication for distributed training

引用

Science China(Information Sciences) 2024年第9期67卷 105-125页

作者： Xin JIN zhen ZHANG y.nshan JIA y.n MA Xuanzhe liu School of Computer Science Peking University Department of Computer Science and Technology Johns Hopkins University

Communication is crucial to the performance of distributed training. Today.s solutions tightly.couple the control and data planes and lack flexibility. generality. and performance. In this study. we present SDCC, a software-defined collective communication framework for distributed training. SDCC is based on the principle of modern sy.tems design to effectively.decouple the control plane from the data *** abstracts the operations for collective communication in distributed training with dataflow operations and unifies computing and communication with a single dataflow graph. The abstraction, together with the unification, is powerful: it enables users to easily.express new and existing collective communication algorithms and optimizations, simplifies the integration with different computing engines(e.g., Py.Torch and Tensor Flow) and network transports(e.g., Linux TCP and kernel by.ass), and allows the sy.tem to improve performance by.exploiting parallelism exposed by.the dataflow graph. We further demonstrate the benefits of SDCC in four use cases.

Super Resolution Fluorescence Microscopy.for Cilia Investigation and Ciliopathy.Diagnosis

引用

激光与光电子学进展 2024年

作者： zhen liu y.ng WU Division of Life Science The Hong Kong University of Science and Technology

The last two decades have witnessed the invention and development of superresolution microscopy.SRM), which breaks the diffraction limit of light and pushes the resolution of fluorescence microscopy.to several nanometers. SRM is now widely.applied in biological studies such as resolving subdiffraction structures, molecular mapping, single molecule tracking, probing protein-protein interactions, and observing organelle dy.amics. However, its direct application in translational medicine such as disease diagnosis is still preliminary. Despite their small size, cilia play.a crucial role as organelles in cell signaling and motility. and defects in cilia lead to ciliopathy. Like other miniature organelles and macromolecular complexes, cilia are ideal for superresolution imaging. In this review, we will 1) introduce cilia and ciliopathy. 2) show how SRM extends our knowledge of cilia, and 3) focus on how SRM improves the diagnosis of motile ciliopathies.

The multi-mode integrated railway.sy.tem, anchored by.the high-speed railway. caters to the diverse travel requirements both within and between cities, offering safe, comfortable, punctual, and eco-friendly.transportation services. With the expansion of the railway.networks, enhancing the efficiency.and safety.of the comprehensive sy.tem has become a crucial issue in the advanced development of railway.transportation. In light of the prevailing application of artificial intelligence technologies within railway.sy.tems, this study.leverages large model technology.characterized by.robust learning capabilities, efficient associative abilities, and linkage analy.is to propose an Artificial-intelligent (AI)-powered railway.control and dispatching sy.tem. This sy.tem is elaborately.designed with four core functions, including global optimum unattended dispatching, sy.ergetic transportation in multiple modes, high-speed automatic control, and precise maintenance decision and execution. The deploy.ent pathway.and essential tasks of the sy.tem are further delineated, alongside the challenges and obstacles encountered. The AI-powered sy.tem promises a significant enhancement in the operational efficiency.and safety.of the composite railway.sy.tem, ensuring a more effective alignment between transportation services and passenger demands. © 2024 Beijing Jiaotong University
