Fast, byte-addressable NVM promises near cache latency and near memory bus throughput
for file system operations. However, unanticipated cache line eviction may lead to …

Emerging non-volatile main memories (NVMMs) provide data persistence at the main
memory level. To avoid the double-copy overheads among the user buffer, the OS page …

Fast non-volatile memories (NVMs) will soon appear on the processor memory bus
alongside DRAM. The resulting hybrid memory systems will provide software with sub …

Modern file systems employ journaling techniques to guarantee data consistency in case of
unexpected system crashes or power failures. However, journaling file systems usually …

The extremely low latency of non-volatile memory (NVM) raises issues of latency in file
systems. In particular, user-kernel context switches caused by system calls and hardware …

Emerging fast, byte-addressable Non-Volatile Main Memory (NVMM) provides huge
increases in storage performance compared to traditional disks. We present Ziggurat, a …

This paper presents crash consistent Non-Volatile Memory Express (ccNVMe), a novel
extension of the NVMe that defines how host software communicates with the non-volatile …

High-performance, byte-addressable non-volatile main memories (NVMMs) force system
designers to rethink trade-offs throughout the system stack, often leading to dramatic …

File system performance is dominated by small and frequent metadata access. Metadata is
stored as blocks on the hard disk drive. Partial metadata update results in whole-block read …

The conventional file system provides a hierarchical namespace by structuring it as a
directory tree. Tree-based namespace structure leads to inefficient file path walk and …
