This paper reports the deployment of computational storage drives in Alibaba Cloud, aiming to enable cloud-native relational database cost-effectively support analytical workloads. With its ...

LSM-based KV stores are designed to offer good write performance, by capturing client writes in memory, and only later flushing them to storage. Writes are later compacted into a tree-like data ...

Nanosecond-level clock synchronization can be an enabler of a new spectrum of timing- and delay-critical applications in data centers. However, the popular clock synchronization algorithm, NTP, can ...

The DNS filtering apparatus of China's Great Firewall (GFW) has evolved considerably over the past two decades. However, most prior studies of China's DNS filtering were performed over short time ...

We present INSIDER, a full-stack redesigned storage system to help users fully utilize the performance of emerging storage drives with moderate programming efforts. On the hardware side, INSIDER ...

USENIX celebrates its 50th anniversary in 2025. We celebrate decades of innovations, experiments, and gatherings of the advanced computing system community. And in the spirit of our ever-evolving ...

Second, we implemented a video encoder intended for fine-grained parallelism, using a functional-programming style that allows computation to be split into thousands of tiny tasks without harming ...

This paper presents an evaluation of the use of a high-level language (HLL) with garbage collection to implement a monolithic POSIX-style kernel. The goal is to explore if it is reasonable to use an ...

In this study, we discover a subtle yet serious timing side channel that exists in all generations of half-duplex IEEE 802.11 or Wi-Fi technology. Previous TCP injection attacks stem from software ...

TLS is one of today's most widely used and best-analyzed encryption technologies. However, for historical reasons, TLS for email protocols is often not used directly but negotiated via STARTTLS. This ...
