pebblesdb

The PebblesDB write-optimized key-value store (SOSP 17)

RECIPE

RECIPE : high-performance, concurrent indexes for persistent memory (SOSP 2019)

crashmonkey

CrashMonkey: tools for testing file-system reliability (OSDI 18)

WineFS

WineFS (SOSP 21): a huge-page aware file system for persistent memory

dinomo

DINOMO: An Elastic, Scalable, High-Performance Key-Value Store for Disaggregated Persistent Memory (PVLDB 2022, VLDB 2023)

optfs

The Optimistic File System (OptFS) is a Linux ext4 variant that implements Optimistic Crash Consistency, a new approach to crash consistency in journaling file systems. OptFS improves performance for many workloads, sometimes by an order of magnitude. OptFS provides strong consistency, equivalent to data journaling mode of ext4.

rustfs

A Rust user-space file system [WIP]

chipmunk

Tool for checking crash-consistency for persistent-memory file systems

pebbles-rocks

Introducing FLSM into the RocksDB key-value store

txlib

A library for doing atomic updates in a file-system agnostic manner.

A Java Native Interface to LevelDB

mongo-pebbles

MongoDB storage integration layer for the PebblesDB storage engine

YCSB

Yahoo! Cloud Serving Benchmark

GDPR

monet-schedules

Pre-solved schedules for MONeT

script_optfs

AutoOsync is a tool that makes libraries OptFS compatible, getting sometimes a performance that's an order of magnitude higher than before, while achieving the same level of safety guarantee. It requires minimal programmer intervention.

LiPT

A Lightweight Distributed Pre-Training Toolkit for Gradient-based Subset Training

CheckFreq

CheckFreq: Frequent, Fine-Grained DNN Checkpointing (FAST 21)

CoorDL

CoorDL: IO-efficient data loading for DNN training (VLDB 21)
