The unrelenting growth of the memory needs of emerging datacenter applications, along
with ever increasing cost and volatility of DRAM prices, has led to DRAM being a major …

Userspace library file systems (LibFSes) promise to unleash the performance potential of
non-volatile memory (NVM) by directly accessing it and enabling unprivileged applications …

Existing file systems for persistent memory (PM) exploit its byte-addressable non-volatile
access with low latency and high bandwidth. However, they do not utilize two unique PM …

Storage Technologies. MadFS: Per-File Virtu Page 1 This paper is included in the …

We present Chipmunk, a new framework to test persistent-memory (PM) file systems for
crash-consistency bugs. Using Chipmunk, we discovered 23 new bugs across five PM file …

Persistent memory (PMem) is a low-latency storage technology connected to the processor
memory bus. The Direct Access (DAX) interface promises fast access to PMem, map** it …

Filesystem fragmentation has been one of the primary reasons for computer systems to get
slower over time. However, there have been rapid changes in modern storage systems over …

Data-intensive applications executing on NVM-based storage systems experience serious
bottlenecks when moving data between DRAM and NVM. We advocate for the use of the …

Compute eXpress Link (CXL) based Solid-State Drives (CXL-SSDs), such as the Samsung
CMM-H model, promise to offer CXL. mem memory and CXL. io block dual-mode interfaces …

Using huge pages has become a mainstream method to reduce address translation
overhead for big memory workloads in modern computer systems. To create huge pages …
