Explore a 14-minute conference talk from FAST '22 that introduces ctFS, a novel contiguous file system designed to optimize performance for persistent memory. Learn how ctFS eliminates the overhead associated with traditional indexing structures by representing files as contiguous regions of virtual memory, leveraging hardware MMU for efficient address translation. Discover the design challenges, implementation details, and performance benefits of ctFS, including its hierarchy code layout, partition organization, and pswap efficiency. Gain insights into how ctFS outperforms existing file systems like ext4-DAX and SplitFS in real-world workloads such as LevelDB, demonstrating significant performance improvements for persistent memory applications.
