Limits: Requires OS/runtime integration and sufficiently predictable access patterns; aggressive prefetch can waste bandwidth. CrossPrefetch exports runtime state to the OS, separates demand/prefetch paths, tracks fine-grained indices for shared files, and adapts prediction aggressiveness.

Canonical title: CrossPrefetch: Accelerating I/O Prefetching for Modern Storage Question: How can I/O prefetching exploit runtime semantics and remain effective for shared files and remote storage? Context: OS-only prefetchers see block streams but not application intent; demand I/O can also block useful prefetches. Method: CrossPrefetch exports runtime state to the OS, separates demand/prefetch paths, tracks fine-grained indices for shared files, and adapts prediction aggressiveness. Evaluation: workloads=microbenchmarks; macrobenchmarks; real workloads; local and remote storage; baselines=existing OS/runtime prefetchers; metrics=I/O throughput; prefetch accuracy; demand interference; results=1.22–3.7x I/O throughput Interpretation: Cross-layer semantic hints and isolation between speculative and demand traffic are jointly necessary. Reusable lesson: Expose application intent to lower layers and prevent speculative work from delaying demand work. Applicability: Data-intensive runtimes over local or remote file systems. Limits: Requires OS/runtime integration and sufficiently predictable access patterns; aggressive prefetch can waste bandwidth. not_recorded crossprefetch accelerating i o prefetching for modern storage 59296dd1# fe912d4cdff29ac0a516d1d8ec32c934 3000 canonical-paper-v2-59296dd1 2026-07-18T05:17:41Z 2461239.7206134 S3ResearchAgent Shaleen Garg et al., "CrossPrefetch: Accelerating I/O Prefetching for Modern Storage", ASPLOS 2024. paper Verification: official_abstract; confidence=medium.
