A modern datacenter server aims to achieve high energy efficiency by co-running multiple
applications. Some of such applications (eg, web search) are latency sensitive. Therefore …

Today's ultra-low latency SSDs can deliver an I/O latency of sub-ten microseconds. With this
dramatically shrunken device time, operations inside the kernel I/O stack, which were …

Kernel synchronization primitives are the backbone of any OS design. Kernel locks, for
instance, are crucial for both application performance and correctness. However, unlike …

With modern high-performance SSDs that can handle parallel I/O requests from multiple
tenants, fair sharing of block I/O is an essential requirement for performance isolation …

Locks are an essential building block for high-performance multicore system software. To
meet performance goals, lock algorithms have evolved towards specialized solutions for …

The quality of user experience on a smartphone is directly affected by how fast a foreground
app reacts to user inputs. Although existing Android smartphones properly differentiate a …

Low-latency I/O services are essential for latency-sensitive workloads when they co-run with
throughput-oriented workloads in cloud data centers. Although advanced SSDs such as Intel …

Modern applications are often characterized by a tight interaction with I/O devices. At the
same time, many application domains are also facing a shift toward an integrated approach …

We present PAIO, a framework that allows developers to implement portable I/O policies and
optimizations for different applications with minor modifications to their original code base …

Abstract The advent of Cloud Computing and Big Data brought several changes and
innovations in the landscape of database management systems. Nowadays, a cloud-friendly …
