    • A New Temperature Distribution Measurement Method on GPU Architectures Using Thermocouples 

      Dasgupta, Aniruddha; Hong, Sunpyo; Kim, Hyesoon; Park, Jinil (Georgia Institute of Technology, 2012)
      In recent years, the many-core architecture has seen a rapid increase in the number of on-chip cores with a much slower increase in die area. This has led to very high power densities in the chip. Hence, in addition to ...
    • 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 ...
    • On the Predictability of Large Transfer TCP Throughput 

      He, Qi; Dovrolis, Constantinos; Ammar, Mostafa H. (Mostafa Hamed) (Georgia Institute of Technology, 2005)
      With the advent of overlay and peer-to-peer networks, Grid computing, and CDNs, network performance prediction becomes an essential task. Predicting the throughput of large TCP transfers, in particular, has attracted much ...
    • Opportunistic Overlays: Efficient Content Delivery in Mobile Ad Hoc Networks 

      Chen, Yuan; Schwan, Karsten (Georgia Institute of Technology, 2005)
      Current content-based publish/subscribe systems assume a fixed network environment in which nodes do not move and where the network topology remains relatively stable. For mobile environments, the resulting problem is a ...
