  - title: "PMAlloc: A Holistic Approach to Improving Persistent Memory Allocation"
    authors:
    - Zheng Dang
    - Shuibing He
    - Xuechen Zhang
    - Peiyi Hong
    - Zhenxin Li
    - Xinyu Chen
    - Haozhe Song
    - Xian-He Sun
    - Gang Chen
    tldr: "PMAlloc redesigns persistent memory allocation end-to-end, co-optimizing the allocator's data structures, concurrency, and crash consistency to dramatically reduce allocation overhead."
    why_notable: "Persistent memory is still poorly understood at the allocator level; this paper offers a rare holistic treatment that will inform future PM software stacks."
  - title: "Boki: Towards Data Consistency and Fault Tolerance with Shared Logs in Stateful Serverless Computing"
    authors:
    - Zhipeng Jia
    - Emmett Witchel
    tldr: "Boki introduces a shared-log abstraction for serverless functions that provides strong consistency and fault tolerance without requiring developers to manage state explicitly."
    why_notable: "It reframes stateful serverless as a log-centric problem, offering a clean systems primitive that substantially simplifies correctness guarantees in function-as-a-service platforms."
  - title: "Diciclo: Flexible User-level Services for Efficient Multitenant Isolation"
    authors:
    - Giorgos Kappes
    - Stergios V. Anastasiadis
    tldr: "Diciclo provides a user-level framework that lets services customize their isolation mechanisms without kernel modifications, reducing interference among co-located tenants."
    why_notable: "Multitenant isolation in cloud systems is typically a blunt instrument; this work shows that flexible, low-overhead isolation can be achieved entirely in user space."
  - title: "SPATA: Effective OS Bug Detection with Summary-Based, Alias-Aware, and Path-Sensitive Typestate Analysis"
    authors:
    - Tuo Li
    - Jia-Ju Bai
    - Yulei Sui
    - Shi-Min Hu
    tldr: "SPATA applies a summary-based, alias-aware, and path-sensitive typestate analysis to detect resource-management bugs in OS kernels at scale."
    why_notable: "Finding use-after-free and double-free bugs in OS code remains an open challenge; SPATA's precision improvements over prior static analyses make it a practical tool for kernel hardening."
  - title: "Trinity: High-Performance and Reliable Mobile Emulation through Graphics Projection"
    authors:
    - Hao Lin
    - Zhenhua Li
    - Di Gao
    - Yunhao Liu
    - Feng Qian
    - Tianyin Xu
    - Bo Xiao
    - Xiaokang Qin
    tldr: "Trinity projects GPU rendering workloads from a mobile device onto a remote high-performance GPU, enabling faithful, high-throughput mobile emulation."
    why_notable: "Mobile app testing at scale requires accurate emulation of GPU behavior; Trinity's graphics-projection design closes a long-standing fidelity gap in mobile emulators."
  - title: "Optimizing Resource Management for Shared Microservices: A Scalable System Design"
    authors:
    - Shutian Luo
    - Chenyu Lin
    - Kejiang Ye
    - Guoyao Xu
    - Liping Zhang
    - Guodong Yang
    - Huanle Xu
    - Cheng-Zhong Xu
    tldr: "This paper presents a scalable resource-management system for shared microservices that reduces interference and improves utilization in large-scale production deployments."
    why_notable: "Microservice co-location is the norm in modern clouds, yet managing their shared resources at scale remains unsolved; this work delivers practical, production-validated answers."
  - title: "Hardware-Software Collaborative Tiered-Memory Management Framework for Virtualization"
    authors:
    - Sai Sha
    - Chuandong Li
    - Xiaolin Wang
    - Zhenlin Wang
    - Yingwei Luo
    tldr: "A hardware-software co-design framework that transparently manages hot/cold data placement across DRAM and slower memory tiers inside virtual machines."
    why_notable: "As CXL-attached and NVM memory tiers become mainstream in data centers, principled tiered-memory management in hypervisors becomes critical; this paper provides a solid baseline."
  - title: "Component-distinguishable Co-location and Resource Reclamation for High-throughput Computing"
    authors:
    - Laiping Zhao
    - Yushuai Cui
    - Yanan Yang
    - Xiaobo Zhou
    - Tie Qiu
    - Keqiu Li
    - Yungang Bao
    tldr: "This system differentiates micro-components of co-located workloads to reclaim idle resources precisely, boosting overall cluster throughput without violating SLOs."
    why_notable: "Coarse-grained co-location wastes significant cluster capacity; the component-level granularity introduced here sets a new standard for resource-reclamation systems."
