LDB is a software-only profiler that samples call stacks using a background thread and records request and synchronization tags to attribute tail latency to… | ||
| Hermit: Low-Latency, High-Throughput, and Transparent Remote Memory... | NSDI 2023 | 2023-04-17 |
Hermit is a kernel swap redesign that implements feedback-directed asynchrony to move expensive, non-urgent work off the page-fault path, adaptively schedule… | ||
| Protego: Overload Control for Applications with Unpredictable Lock Contention | NSDI 2023 | 2023-04-17 |
Protego implements an Active Synchronization Queue Management (ASQM) that aborts requests whose remaining lock-wait budget cannot meet SLOs, plus a… | ||
| Nu: Achieving Microsecond-Scale Resource Fungibility with Logical Processes | NSDI 2023 | 2023-04-17 |
A system called Nu implements logical processes that split a Unix process into many small stateful proclets and a centralized controller, and it migrates those… | ||
