    • Dynamic Differential Data Protection for High Performance and Pervasive Applications 

      Widener, Patrick M. (Patrick McCall); Schwan, Karsten (Georgia Institute of Technology, 2004)
      Modern distributed applications are long-lived, are expected to provide flexible and adaptive data services, and must meet the functionality and scalability challenges posed by dynamically changing user communities in ...
    • e-SAFE: An Extensible Secure and Fault Tolerant Storage System 

      Paul, Arnab; Agarwala, Sandip; Ramachandran, Umakishore (Georgia Institute of Technology, 2005)
      With the rapidly falling price of hardware, and increasingly available bandwidth, storage technology is seeing a paradigm shift from centralized and managed mode to distributed and unmanaged configurations. The key issues ...
    • Efficient and Secure Search of Enterprise File Systems 

      Singh, Aameek; Srivatsa, Mudhakar; Liu, Ling (Georgia Institute of Technology, 2007)
      With fast paced growth of enterprise data, quickly locating relevant content has become a critical IT capability. Research has shown that nearly 85% of enterprise data lies in flat filesystems [12] that allow multiple ...
    • Evaluating Scalability of Multi-threaded Applications on a Many-core Platform 

      Gupta, Vishal; Kim, Hyesoon; Schwan, Karsten (Georgia Institute of Technology, 2012)
      Multicore processors have been effective in scaling application performance by dividing computation among multiple threads running in parallel. However, application performance does not necessarily improve as more cores ...
    • Generating Perfect Reversals of Simple Linear-Codes 

      Perumalla, Kalyan S. (Georgia Institute of Technology, 2003)
      Bi-directional execution - executing forward as well as in reverse - is useful in many contexts. However, traditional techniques for bi-directional execution are not scalable, as they require infinite storage in the ...
    • High-Fidelity Modeling of Computer Network Worms 

      Perumalla, Kalyan S.; Sundaragopalan, Srikanth (Georgia Institute of Technology, 2004-06-23)
      Abstract modeling, such as using epidemic models, has been the general method of choice for understanding and analyzing the high-level effects of worms. However, high-fidelity models, such as packet-level models, are ...
    • O2S2: Enhanced Object-based Virtualized Storage 

      Raj, Himanshu; Schwan, Karsten (Georgia Institute of Technology, 2007)
      Object based storage devices (OSDs) elevate the level of abstraction presented to clients, thereby permitting them to offer methods for managing, sharing, and securing information that go beyond those offered by ...
    • Profile-Guided Microarchitectural Floorplanning for Deep Submicron Processor Design 

      Ekpanyapong, Mongkol; Minz, Jacob Rajkumar; Watewai, Thaisiri; Lee, Hsien-Hsin Sean; Lim, Sung Kyu (Georgia Institute of Technology, 2003)
      As process technology migrates to deep submicron with feature size less than 100nm, global wire delay is becoming a major hindrance in keeping the latency of intra-chip communication within a single cycle, thus decaying ...
    • Scalable Access Control in Content-Based Publish-Subscribe Systems 

      Srivatsa, Mudhakar; Liu, Ling (Georgia Institute of Technology, 2006)
      Content-based publish-subscribe (pub-sub) systems are an emerging paradigm for building a large number of distributed systems. Access control in a pub-sub system refers to secure distribution of events to clients subscribing ...
    • Scalable Simulation of Electromagnetic Hybrid Codes 

      Perumalla, Kalyan S.; Dave, Jagrut Durdant; Fujimoto, Richard M.; Karimabadi, Homa; Driscoll, Jonathan; Omelchenko, Yuri (Georgia Institute of Technology, 2005)
      New discrete-event formulations of physics simulation models are emerging that can outperform models based on traditional time-stepped techniques. Detailed simulation of the Earth s magnetosphere, for example, requires ...
    • Virtualization Services: Accelerated I/O Support in Multi-Core Systems 

      Raj, Himanshu; Schwan, Karsten (Georgia Institute of Technology, 2010)
      Virtualization services permit I/O subsystems and peripheral devices to be virtualized by placing select functionality on specialized cores and/or on cores situated ‘closer’ to devices. The approach is used to implement ...
