The recent advancement of high-bandwidth I/O devices enables scalable delivery of online
content. Unfortunately, the traditional programming model for content servers has a tight …

Fast non-volatile memory (NVM) technology changes the landscape of file systems. A series
of research efforts to overcome the traditional file system designs that limit NVM …

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 …

Recently, with the emergence of low-latency NVM storage, software overhead has become a
greater bottleneck than storage latency, and memory mapped file I/O has gained attention as …

Emerging big-data workloads with massive I/O processing require fast, scalable, and flexible
storage virtualization support. Hardware-assisted virtualization can achieve reasonable …

There has been an arms race for devising accelerators for deep learning in recent years.
However, real-world applications are not only neural networks but often span across …

Bare-metal instances are crucial for high-value, mission-critical applications on the cloud.
Tenants exclusively use these dedicated hardware resources. Local virtualized disks are …

Accelerators like Graphics Processing Units (GPUs) have been increasingly deployed in
modern data centers because of their compute capabilities and memory bandwidth. These …

We propose FlashGPU, a new GPU architecture that tightly blends new flash (Z-NAND) with
massive GPU cores. Specifically, we replace global memory with Z-NAND that exhibits ultra …

We propose Solros---a new operating system architecture for heterogeneous systems that
comprises fast host processors, slow but massively parallel co-processors, and fast I/O …
