- title: "Whole-system Persistence Made Efficient with Tree-structured Checkpointing on Microkernel"
|
|
authors:
|
|
- Mingkai Dong
|
|
- Fangnuo Wu
|
|
- Gequan Mo
|
|
- Haibo Chen
|
|
tldr: "A microkernel-based whole-system persistence scheme uses tree-structured incremental checkpointing to achieve low-overhead, crash-consistent snapshots of the entire OS state."
|
|
why_notable: "Whole-system persistence is a foundational building block for reliable systems; this paper shows it can be done efficiently within a microkernel architecture."

- title: "XpuTEE: A High-Performance and Practical Heterogeneous Trusted Execution Environment for GPUs"
|
|
authors:
|
|
- Shulin Fan
|
|
- Zhichao Hua
|
|
- Yubin Xia
|
|
- Haibo Chen
|
|
tldr: "XpuTEE extends trusted execution environments to GPUs by designing a hardware-assisted isolation mechanism that protects GPU computations with low performance overhead."
|
|
why_notable: "As GPUs process sensitive ML workloads in shared clouds, TEE support for accelerators is urgently needed; XpuTEE is a comprehensive and practical solution."

|
- Wenbo Shen
|
|
- Yajin Zhou
|
|
- Rui Chang
|
|
tldr: "RegVault II uses hardware features to selectively randomize sensitive kernel data structures at runtime across multiple ISAs, raising the bar for kernel exploitation."
|
|
why_notable: "Kernel data-only attacks bypass existing code-randomization defenses; this work's multi-architecture approach makes selective data randomization practical for production kernels."
|
|
- title: "Validating JIT Compilers via Compilation Space Exploration"
|
|
authors:
|
|
- Cong Li
|
|
- Yanyan Jiang
|
|
- Chang Xu
|
|
- Zhendong Su
|
|
tldr: "Compilation space exploration systematically generates and tests the large space of valid JIT compilation outcomes to find miscompilation bugs in production JIT compilers."
|
|
why_notable: "JIT correctness is notoriously hard to test; this paper's systematic exploration strategy finds real bugs in widely-used runtimes and advances the state of compiler validation."
|
|
- title: "Freezing-based Memory and Process Co-design for User Experience on Resource-limited Mobile Devices"
|

|
- Rachata Ausavarungnirun
|
|
- Liang Shi
|
|
- Xuehai Zhou
|
|
tldr: "A co-designed memory and process management scheme freezes background processes at fine granularity to reclaim memory while preserving fast resume latency on constrained mobile hardware."
|
|
why_notable: "Mobile memory pressure directly degrades user experience; this paper's co-design perspective yields measurable improvements on real devices with limited resources."

|
- Varun S. Girimaji
|
|
- Mai Zheng
|
|
tldr: "This work systematically analyzes the dependency graph among file-system configuration options to reveal hidden interactions that lead to silent data corruption or crashes."
|
|
why_notable: "File-system misconfiguration is a major source of data loss in practice; understanding configuration dependencies is essential for building safer storage systems."
|
|
- title: "Efficient Fault Tolerance for Stateful Serverless Computing with Asymmetric Logging"
|
|
authors:
|
|
- Sheng Qi
|
|
- Haoyu Feng
|
|
- Xuanzhe Liu
|
|
- Xin Jin
|
|
tldr: "Asymmetric logging decouples the logging cost between the fast and slow paths of stateful serverless functions, enabling low-overhead fault tolerance without sacrificing recovery guarantees."
|
|
why_notable: "Fault tolerance for stateful serverless remains an open performance challenge; this paper's asymmetric design significantly reduces logging overhead compared to symmetric approaches."
|
|
- title: "Towards Serialization/Deserialization-free State Transfer in Serverless Workflows"
|

|
|
tldr: "This system eliminates serialization and deserialization costs when passing state between serverless functions by enabling direct in-memory state transfer across workflow stages."
|
|
why_notable: "Ser/deser overhead is a dominant cost in serverless workflows; removing it fundamentally changes the performance profile of function chaining at scale."
|
