Dynamic Binary Instrumentation of OS Kernel, Driver and BIOS

We introduce the Intel® Simulation and Analysis Engine (Intel® SAE) --- a framework for full-system instruction-level instrumentation of "ring 0" (privileged) and "ring 3" (user-level) code behavior on x86 platforms. When plugged-in to a Wind River® Simics Virtual Platform, Intel® SAE boots native operating systems (e.g. Linux and Windows, as well as Android), running unmodified binaries while facilitating flexible and customizable instruction-level instrumentation of everything executing on the CPU, i.e. BIOS, kernel, drivers and all kernel and user-space processes. Beyond its ability to instrument a single system, Intel SAE is capable of distributed node-to-node multi-system simulation and instrumentation, useful for analysis of enterprise-scale workloads, such as CloudSuite, Hadoop, Memcached etc.

Vijay Janapa Reddi is an Assistant Professor in the Department of Electrical and Computer Engineering at The University of Texas at Austin. His research interests include system architecture and software design and implementation to address performance, power, and reliability issues in mobile and high-performance computing systems. He is the co-author of widely used tools, e.g., the Pin user-space dynamic binary instrumentation engine and the GPUWattch power modeling simulation framework. He is the recipient of the NAE Gilbreth Lectureship Award, Intel Early Career Award, PLDI Most Influential Paper Award, and has received Best Paper and Top Picks awards in Computer Architecture. Beyond his research activities, Vijay is very passionate about STEM education, particularly involving computer science education starting at an early age. He is responsible for the Hands-On Computer Science (HaCS) curriculum that teaches computer science to 6th graders in the Austin Independent School District (AISD) through Arduino-based hands-on projects. AISD ties directly into the heart of the public education system in Austin--Texas. Vijay received his Ph.D. in Computer Science from Harvard University. He can be contacted at
