Limits: Only an official institutional summary is preserved, so exact workloads, baselines, and all quantitative breakdowns remain unverified. EasyIO uses an on-chip DMA engine for asynchronous data movement, user-level task scheduling, orderless parallel data/metadata updates, two-stage locking with hardware-assisted unlock, and adaptive DMA-channel/QoS control. S3ResearchAgent low Venue: EuroSys. Year: 2024. The work targets slow/high-latency memory filesystems, including persistent and CXL-attached memory; it is not a GPU-storage runtime. Verification: official institutional paper summary; full paper not preserved; confidence=low. 2026-07-16T14:58:27Z 2461238.1239236 Exploring the Asynchrony of Slow Memory Filesystem with EasyIO. EuroSys 2024. DMA-backed asynchronous access can turn storage wait into CPU capacity for user-level tasks, but correctness and QoS require order relaxation, deadlock-safe locking, and channel control. The preserved source does not support the current GPU framing. Exploring the Asynchrony of Slow Memory Filesystem with EasyIO workloads=high-latency memory filesystem evaluation summarized by the authors’ institution; baselines=traditional synchronous-memory-access filesystem; metrics=CPU consumption required to reach peak bandwidth and throughput at equal CPU resources; results=EasyIO reduces the CPU needed for peak bandwidth by up to 88% and improves throughput by 1.03–2.3× at the same CPU allocation. Detailed workload and per-configuration tables require the full paper. How can a filesystem reduce CPU storage tax when persistent, CXL-attached, or other high-latency memory makes synchronous access expensive? lab For slow-memory filesystems, co-design asynchronous DMA, task scheduling, update ordering, locking, and channel QoS; do not transpose the result to GPU copy engines without direct evidence.

Canonical title: EasyIO: Efficient Asynchronous I/O for GPU-Accelerated Storage Systems Question: How can storage I/O be overlapped with fine-grained GPU work without repeated CPU mediation and memory-movement overhead? Context: GPU-accelerated storage paths pay for data movement, synchronization, and ordering around asynchronous requests. Method: EasyIO offloads movement to on-chip DMA, exposes completion-buffer-centric orderless operations, uses two-level locking, and schedules DMA channels by traffic. Evaluation: workloads=; baselines=; metrics=; results=The paper reports that fine-grained tasks can be interleaved transparently with asynchronous I/O; exact headline numbers were not recoverable from the accessible primary text. Interpretation: Treat completion buffers, rather than submission order, as the unit that connects storage progress to GPU work. Reusable lesson: Decouple request ordering from data readiness and schedule scarce copy engines explicitly. Applicability: GPU storage runtimes with controllable DMA engines and many small independent tasks.
