| Xkernel: Principled Performance Tunability of Operating System Kernels | 20th USENIX Symposium on Operating Systems Design and Implementation (OSDI '26) | 2026-07-13 |
Xkernel converts frozen Linux perf-consts into safe, in-situ knobs by synthesizing runtime handlers via Scoped Indirect Execution; it finds constants with… | ||
| Come Hell or Still Water: Alleviating Tail Latency in Cloud Block Store | NSDI '26 | 2026-05-04 |
Per-proxy dual-bucket token buckets add a main bucket (refilled every 10 ms) and a check bucket that only steady segments can draw from; hot segments drain the… | ||
| CCC: Re-architecting Delay-based Congestion Control in Datacenter Networks | NSDI '26 | 2026-05-04 |
Claims that delay signals alone can match switch-assisted CC by adding a CiD trustworthiness layer that splits operating space into regions and switches… | ||
| eTran: Extensible Kernel Transport with eBPF | NSDI '25 | 2025-04-28 |
eTran extends eBPF to create an extensible in-kernel transport that adds new XDP hooks and a packet Q BPF map for queuing, plus XDP egress and XDP gym to… | ||
| CrossMapping: Harmonizing Memory Consistency in Cross-ISA Binary Translation | USENIX ATC 2024 | 2024-07-10 |
CrossMapping is a framework that generates concrete fence- and RMW-mapping schemes for cross-ISA DBT, implemented on QEMU and evaluated with PARSEC. It uses… | ||
| Revisiting Congestion Control for Lossless Ethernet | 21st USENIX Symposium on Networked Systems Design and Implementation (NSDI '24) | 2024-04-16 |
Revisits lossless Ethernet congestion control and proposes ACK-driven congestion control (ACC) that uses receiver ACK time series and packet conservation to… | ||
| Re architecting Congestion Management in Lossless Ethernet | NSDI 2020 | 2020-02-25 |
Claims that existing lossless Ethernet congestion control fails because congestion detection and rate adjustment are ineffective and replaces them with… | ||
