Datacenter systems and I/O devices now run at single-digit microsecond latencies, requiring
ns-scale operating systems. Traditional kernel-based operating systems impose an …

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 …

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

We present uFS, a user-level filesystem semi-microkernel. uFS takes advantage of a high-
performance storage development kit to realize a fully-functional, crash-consistent, highly …

The availability of non-volatile main memory (NVMM) has started a new era for storage
systems and NVMM specific file systems can support extremely high data and metadata …

Graphics Processing Units (GPUs) have traditionally relied on the host CPU to initiate
access to the data storage. This approach is well-suited for GPU applications with known …

Non-volatile memory (NVM) has emerged as a new memory media, resulting in a hybrid
NVM/DRAM configuration in typical servers. Memory-intensive applications competing for …

We present FusionFS, a direct-access firmware-level in-storage filesystem that exploits the
near-storage computational capability for fast I/O and data processing, consequently …

Due to the host-centric design principle, the existing page cache management suffers from
CPU consumption, communication costs, and garbage collection (GC) interference. To …

Traditionally, I/O systems have been developed within the confines of a centralized OS
kernel. This led to monolithic and rigid storage systems that are limited by low development …
