Analyzing the behavior of running programs has a wide variety of compelling applications,
from intrusion detection and prevention to bug discovery. Unfortunately, the high runtime …

Transient faults are emerging as a critical concern in the reliability of general-purpose
microprocessors. As architectural trends point toward multicore designs, there is substantial …

The locality metrics are many, for example, miss ratio to test performance, data footprint to
manage cache sharing, and reuse distance to analyze and optimize a program. It is unclear …

As multicore processors are deployed in mainstream computing, the need for software tools
to help parallelize programs is increasing dramatically. Data-dependence profiling is an …

This paper presents Spectral Profiling, a new method for profiling program execution without
instrumenting or otherwise affecting the profiled system. Spectral Profiling monitors EM …

Dynamic data flow tracking (DFT) is a technique broadly used in a variety of security
applications that, unfortunately, exhibits poor performance, preventing its adoption in …

In profiling, a tradeoff exists between information and overhead. For example, hardware-
sampling profilers incur negligible overhead, but the information they collect is consequently …

Cycle-level micro architectural simulation is the de-facto standard to estimate performance of
next-generation platforms. Unfortunately, the level of detail needed for accurate simulation …

Fast track is a software speculation system that enables unsafe optimization of sequential
code. It speculatively runs optimized code to improve performance and then checks the …

Detecting data races in multithreaded programs is a crucial part of debugging such
programs, but traditional data race detectors are too slow to use routinely. This paper shows …
