The authors present a postcompiler program manipulation tool called Dyninst, which provides a C++ class library for program instrumentation. Using this library, it is possible to instrument and modify application programs during execution. A unique feature of this library is that it permits machine-independent binary instrumentation programs to be written. The authors describe the interface that a tool sees when using this library. They also discuss three simple tools built using this interface: a utility to count the number of times a function is called, a program to capture the output of an already running program to a file, and an implementation of conditional breakpoints. For the conditional breakpoint example, the authors show that by using their interface compared with gdb, they are able to execute a program with conditional breakpoints up to 900 times faster.read more

Self-healing multitier architectures using cascading rescue points
TL;DR: A tool is developed that implements cascading rescue points (CRPs) by dynamically instrumenting binaries and transparently injecting notifications in the already established TCP channels between applications, and shows that it allows them to successfully recover from errors, while incurring moderate overhead.

Dynamic program instrumentation for scalable performance tools
TL;DR: This work presents a new technique called 'dynamic instrumentation' that provides efficient, scalable, yet detailed data collection for large-scale parallel applications and includes recommendations to operating system designers, compiler writers, and computer architects about the features necessary to permit efficient monitoring of large- scale parallel systems.
