| Octopus: Enhancing CXL Memory Pods via Sparse Topology | NSDI '26 | 2026-05-04 |
Octopus constructs a sparse CXL topology that groups servers into islands (BIBD intra-island, expander inter-island) to trade overlap for pooling efficiency. A… | ||
| Enhancing Network Failure Mitigation with Performance-Aware Ranking | NSDI '25 | 2025-04-28 |
Swarm ranks mitigation actions by directly estimating end-to-end flow metrics using fast approximations: epoched traffic samples, splitting short/long flows… | ||
| Managing Memory Tiers with CXL in Virtualized Environments | 18th USENIX Symposium on Operating Systems Design and Implementation (OSDI '24) | 2024-07-10 |
Introduces Intel Flat Memory Mode, a hardware-managed, cacheline-granular CXL tier that acts as a direct-map exclusive cache with zero CPU overhead and… | ||

Hyrax lets servers continue hosting VMs with failed but degradable components by disabling faulty parts (using an uncommon rank-bitmask deactivation for DIMMs)… | ||
| Ensō: A Streaming Interface for NIC-Application Communication | OSDI 2023 | 2023-07-10 |
Replaces packetized NIC-CPU buffers with a contiguous ring streaming pipe that presents an unbounded byte stream, removing per-packet descriptors and enabling… | ||
| C2DN: How to Harness Erasure Codes at the Edge for Efficient Content Delivery | 19th USENIX Symposium on Networked Systems Design and Implementation (NSDI '22) | 2022-04-04 |
Analyzes month-long logs from over 2000 clusters and implements C2DN on Apache Traffic Server, replacing replication with erasure coding plus targeted parity… | ||
| Learning Relaxed Belady for Content Distribution Network Caching | NSDI 2020 | 2020-02-25 |
A machine‑learned cache replacement called Relaxed Belady approximates Belady’s MIN by treating all items beyond a chosen time boundary equally and evicting a… | ||
