Binary rewriting is changing the semantics of a program without having the source code at
hand. It is used for diverse purposes, such as emulation (eg, QEMU), optimization (eg …

Virtual Machine technology applies the concept of virtualization to an entire machine,
circumventing real machine compatibility constraints and hardware resource constraints to …

Innovative systems research hinges on the ability to easily instrument and extend existing
operating system and application functionality. With access to appropriate source code, it is …

This thesis addresses the challenges of building a software system for general-purpose
runtime code manipulation. Modern applications, with dynamically-loaded modules and …

This paper presents DTrace, a new facility for dynamic instrumentation of production
systems. DTrace features the ability to dynamically instrument both user-level and kernel …

While algorithms for cooperative proxy caching have been widely studied, little is
understood about cooperative-caching performance in the large-scale World Wide Web …

This article presents a practical solution for the cyclic debugging of nondeterministic parallel
programs. The solution consists of a combination of record/replay with automatic on-the-fly …

Efficient tracing of system-wide execution, allowing integrated analysis of both kernel space
and user space, is something difficult to achieve. The following article will present you a new …

Ksplice allows system administrators to apply patches to their operating system kernels
without rebooting. Unlike previous hot update systems, Ksplice operates at the object code …

Most systems contain software with yet-to-be-discovered security vulnerabilities. When a
vulnerability is disclosed, administrators face the grim reality that they have been running …
