| StriaTrace: Efficient Tracing and Diagnosis for Online LLM Inference | 20th USENIX Symposium on Operating Systems Design and Implementation (OSDI '26) | 2026-07-13 |
StriaTrace implements host and device collectors that record only 13 synchronization spans and kernel boundaries plus memory transfers, with a pass-by sampler… | ||
| Here, There and Everywhere: The Past, the Present and the Future of Local Storage in... | FAST '26 | 2026-02-24 |
Cloud local storage evolution is traced from Espresso (SPDK user-space poll), which cuts kernel context-switch overhead but wastes CPU (99% of nodes show <60%… | ||
| CacheSlide: Unlocking Cross Position-Aware KV Cache Reuse for Accelerating LLM Serving | FAST '26 | 2026-02-24 |

| How Soon is Now? Preloading Images for Virtual Disks with ThinkAhead | FAST '26 | 2026-02-24 |
Trace analysis of ~160,000 image loads finds lazy loading causes 40% of slow I/Os (>1s), so ThinkAhead preloads blocks using score-based block selection… | ||
| SkySync: Accelerating File Synchronization with Collaborative Delta Generation | FAST '26 | 2026-02-24 |
SkySync reuses storage-layer checksums to avoid recomputing chunk digests, implements CRC32 checksum combining to derive misaligned content-defined chunks, and… | ||
| ParaSync: Exploiting Fine-Grained Parallelism for Efficient File Synchronization | FAST '26 | 2026-02-24 |
ParaSync breaks the CDC sync bottlenecks by (1) multi-threaded chunking that computes CRC32 per sub-chunk and merges checksums via checksum combination instead… | ||
| Chitu: Avoiding Unnecessary Fallback in Byzantine Consensus | USENIX ATC '25 | 2025-07-07 |
Chitu is an asynchronous DAG BFT protocol that tries a fast path based only on message exchange and falls back to coin or leader only when proposals diverge… | ||
| One-Size-Fits-None: Understanding and Enhancing Slow-Fault Tolerance in Modern... | NSDI '25 | 2025-04-28 |
A systematic testing pipeline injects diverse slow faults into six modern distributed systems and sweeps ~100k fault combinations including 8000 configuration… | ||
| Vegeta: Enabling Parallel Smart Contract Execution in Leaderless Blockchains | NSDI '25 | 2025-04-28 |
The paper proposes speculate-order-replay: nodes pre-execute transactions, build a dependency graph, then deterministically replay and validate read/write… | ||
| Acoustic Sensing and Communication Using Metasurface | NSDI 2023 | 2023-04-17 |
System combines a passive 16×16 metasurface with a tiny speaker array and joint optimization of metasurface phase, speaker codebook, and geometry to steer… | ||
| Perseus: A Fail-Slow Detection Framework for Cloud Storage Systems | FAST '23: 21st USENIX Conference on File and Storage Technologies | 2023-02-21 |
Perseus detects fail-slow drives non‑intrusively by modeling latency versus throughput with a light regression model, using outlier removal, an adaptive upper… | ||
| NVMe SSD Failures in the Field: the Fail-Stop and the Fail-Slow | USENIX ATC '22 | 2022-07-11 |
Logs from 1.8 million NVMe SSDs at Alibaba drive these claims: infant mortality disappears (failure rates in months one–three are at or below long‑term rates)… | ||
| MAPX: Controlled Data Migration in the Expansion of Decentralized Object Based Storage | FAST '20 | 2020-02-24 |
MAPX extends CRUSH by adding a virtual layer beneath root for each expansion and controlling Placement Group placement via static and dynamic PG timestamps… | ||
