A Differential Approach to Undefined Behavior Detection
Xi Wang, Nickolai Zeldovich, M. Frans Kaashoek, Armando Solar-Lezama
Article No.: 1
DOI: 10.1145/2699678

This article studies undefined behavior arising in systems programming languages such as C/C++. Undefined behavior bugs lead to unpredictable and subtle systems behavior, and their effects can be further amplified by compiler...

Energy-Oriented Partial Desktop Virtual Machine Migration
Nilton Bila, Eric J. Wright, Eyal De Lara, Kaustubh Joshi, H. Andrés Lagar-Cavilla, Eunbyung Park, Ashvin Goel, Matti Hiltunen, Mahadev Satyanarayanan
Article No.: 2
DOI: 10.1145/2699683

Modern offices are crowded with personal computers. While studies have shown these to be idle most of the time, they remain powered, consuming up to 60% of their peak power. Hardware-based solutions engendered by PC vendors (e.g., low-power...

ISA Wars: Understanding the Relevance of ISA being RISC or CISC to Performance, Power, and Energy on Modern Architectures
Emily Blem, Jaikrishnan Menon, Thiruvengadam Vijayaraghavan, Karthikeyan Sankaralingam
Article No.: 3
DOI: 10.1145/2699682

RISC versus CISC wars raged in the 1980s when chip area and processor design complexity were the primary constraints and desktops and servers exclusively dominated the computing landscape. Today, energy and power are the primary design constraints...
