Improving Processor Efficiency By Statically Pipelining Instructions, Ian Finlayson, Brandon Davis, Peter Gavin, Gang-Ryung Uh, David Whalley, Magnus Sjalander, Gary Tyson

Gang-Ryung Uh

A new generation of applications requires reduced power consumption without sacrificing performance. Instruction pipelining is commonly used to meet application performance requirements, but some implementation aspects of pipelining are inefficient with respect to energy usage. We propose static pipelining as a new instruction set architecture to enable more efficient instruction flow through the pipeline, which is accomplished by exposing the pipeline structure to the compiler. While this approach simplifies hardware pipeline requirements, significant modifications to the compiler are required. This paper describes the code generation and compiler optimizations we implemented to exploit the features of this architecture. We show that …

Editorial: High-Tech Lust, Katina Michael

Professor Katina Michael

Are you in love with your Android or Apple device? Do you have a deep affection and suffer from separation anxiety [1] when your smartphone is not within arm’s length of your bed at night?

Don’t worry, you’re not alone. Rossiter [1] differentiates between “brand love” and “brand liking” which is significant. When it comes to our high-tech gadgetry people are likely to be able to cope better with being separated from a partner or child than being separated from a vital piece of technology which goes with them everywhere.

Consumer Driven Innovation Management, Arcot Desai Narasimhalu, Shekhar Mitra

Arcot Desai NARASIMHALU

The evolution of human society leads to increased affluence and prosperity of certain populations, sometimes at the expense of well-established markets. Market leaders in products and services tend to be so focused on their current customer base that they are caught off guard with the changes in markets created by the evolution. These changes often go unnoticed until it is too late. The change in customer base often requires the repositioning of products and services through innovations, which address new and emerging markets. Some of these changes could potentially result in tectonic market shifts that force innovation managers to involve …

F-Trail: Finding Patterns In Taxi Trajectories, Yasuko Matsubara, Evangelos Papalexakis, Lei Li, David Lo, Yasushi Sakurai, Christos Faloutsos

David LO

Given a large number of taxi trajectories, we would like to find interesting and unexpected patterns from the data. How can we summarize the major trends, and how can we spot anomalies? The analysis of trajectories has been an issue of considerable interest with many applications such as tracking trails of migrating animals and predicting the path of hurricanes. Several recent works propose methods on clustering and indexing trajectories data. However, these approaches are not especially well suited to pattern discovery with respect to the dynamics of social and economic behavior. To further analyze a huge collection of taxi trajectories, …

A Comparative Study Of Supervised Learning Algorithms For Re-Opened Bug Prediction, Xin Xia, David Lo, Xinyu Wang, Xiaohu Yang, Shanping Li, Jianling Sun

David LO

Bug fixing is a time-consuming and costly job which is performed in the whole life cycle of software development and maintenance. For many systems, bugs are managed in bug management systems such as Bugzilla. Generally, the status of a typical bug report in Bugzilla changes from new to assigned, verified and closed. However, some bugs have to be reopened. Reopened bugs increase the software development and maintenance cost, increase the workload of bug fixers, and might even delay the future delivery of a software. Only a few studies investigate the phenomenon of reopened bug reports. In this paper, we evaluate …
