| Johnny Cache: the End of DRAM Cache Conflicts (in Tiered Main Memory Systems) | OSDI 2023 | 2023-07-10 |
Shows that treating DRAM as a hardware cache works if conflicts are eliminated: two low-overhead techniques—static page-allocation that avoids overlapping… | ||
| Fewer Cores, More Hertz: Leveraging High-Frequency Cores in the OS Scheduler for | USENIX ATC '20 | 2020-07-15 |
Identifies a concrete problem—frequency inversion—caused by per‑core DVFS and long frequency transition latencies (measured 29 ms rise and 98 ms fall)… | ||
| SILK: Preventing Latency Spikes in Log-Structured Merge Key-Value Stores | USENIX ATC '19 | 2019-07-10 |
Implements an I/O scheduler inside RocksDB that allocates bandwidth opportunistically, prioritizes lower-level work and preempts higher-level compactions to… | ||
| Size-aware Sharding For Improving Tail Latencies in In-memory Key-value Stores | NSDI 2019 | 2019-02-26 |
Minos implements size-aware sharding in an in-memory KV store (DPDK, 8 cores, 40 Gb NIC) by partitioning cores into disjoint small/large sets, using a runtime… | ||
