UNISIM: An Open Simulation Environment and Library for Complex Architecture Design and Collaborative Development
Found in: IEEE Computer Architecture Letters
By David August, Jonathan Chang, Sylvain Girbal, Daniel Gracia-Perez, Gilles Mouchard, David A. Penry, Olivier Temam, Neil Vachharajani
Issue Date:July 2007
pp. 45-48
Simulator development is already a huge burden for many academic and industry research groups; future complex or heterogeneous multi-cores, as well as the multiplicity of performance metrics and required functionality, will make matters worse. We present a...
 
Automatic Instruction-Level Software-Only Recovery
Found in: IEEE Micro
By George A. Reis, Jonathan Chang, David I. August
Issue Date:January 2007
pp. 36-47
Software-only reliability techniques protect against transient faults without the overhead of hardware techniques. However, although existing low-level software-only fault-tolerance techniques detect faults, they offer no recovery assistance. This article ...
 
Automatic Instruction-Level Software-Only Recovery
Found in: Dependable Systems and Networks, International Conference on
By Jonathan Chang, George A. Reis, David I. August
Issue Date:June 2006
pp. 83-92
As chip densities and clock rates increase, processors are becoming more susceptible to transient faults that can affect program correctness. Computer architects have typically addressed reliability issues by adding redundant hardware, but these techniques...
 
Design and Evaluation of Hybrid Fault-Detection Systems
Found in: Computer Architecture, International Symposium on
By George A. Reis, Jonathan Chang, Neil Vachharajani, Ram Rangan, David I. August, Shubhendu S. Mukherjee
Issue Date:June 2005
pp. 148-159
<p>As chip densities and clock rates increase, processors are becoming more susceptible to transient faults that can affect program correctness. Up to now, system designers have primarily considered hardware-only and software-only fault-detection mec...
 
SWIFT: Software Implemented Fault Tolerance
Found in: Code Generation and Optimization, IEEE/ACM International Symposium on
By George A. Reis, Jonathan Chang, Neil Vachharajani, Ram Rangan, David I. August
Issue Date:March 2005
pp. 243-254
To improve performance and reduce power, processor designers employ advances that shrink feature sizes, lower voltage levels, reduce noise margins, and increase clock rates. However, these advances make processors more susceptible to transient faults that ...
 
RIFLE: An Architectural Framework for User-Centric Information-Flow Security
Found in: Microarchitecture, IEEE/ACM International Symposium on
By Neil Vachharajani, Matthew J. Bridges, Jonathan Chang, Ram Rangan, Guilherme Ottoni, Jason A. Blome, George A. Reis, Manish Vachharajani, David I. August
Issue Date:December 2004
pp. 243-254
Even as modern computing systems allow the manipulation and distribution of massive amounts of information, users of these systems are unable to manage the confidentiality of their data in a practical fashion. Conventional access control security mechanism...
 
Analysis And Detection of Timing Failures In An Experimental Test Chip
Found in: Test Conference, International
By Piero Franco, Siyad Ma, Jonathan Chang, Yi-Chin Chu, Sanjay Wattal, E. J. McCluskey, Robert L. Stokes, William D. Farwell
Issue Date:October 1996
pp. 691
A 25k gate Test Chip was designed and manufactured to evaluate different test methods for scan-designed circuits. The design of the chip, the experiment, and preliminary experimental results were presented at ITC'95. This paper presents results for differe...
 
Comparison of child-human and child-computer interactions based on manual annotations
Found in: Proceedings of the 2nd Workshop on Child, Computer and Interaction (WOCCI '09)
By Jeannette Chang, Jonathan Chang, Matthew Black, Shrikanth Narayanan
Issue Date:November 2009
pp. 1-6
Technological advancements in recent years have been accompanied by a notable increase in research related to conversational child-machine interfaces. The technology has many applications from entertainment to education. In order to integrate this technolo...
     
Connections between the lines: augmenting social networks with text
Found in: Proceedings of the 15th ACM SIGKDD international conference on Knowledge discovery and data mining (KDD '09)
By David M. Blei, Jonathan Chang, Jordan Boyd-Graber
Issue Date:June 2009
pp. 1-24
Network data is ubiquitous, encoding collections of relationships between entities such as people, places, genes, or corporations. While many resources for networks of interesting entities are emerging, most of these can only annotate connections in a limi...
     
Software-controlled fault tolerance
Found in: ACM Transactions on Architecture and Code Optimization (TACO)
By David I. August, George A. Reis, Jonathan Chang, Neil Vachharajani, Ram Rangan, Shubhendu S. Mukherjee
Issue Date:December 2005
pp. 366-396
Traditional fault-tolerance techniques typically utilize resources ineffectively because they cannot adapt to the changing reliability and performance demands of a system. This paper proposes software-controlled fault tolerance, a concept allowing designer...
