Research

I am interested in designing, building, and evaluating systems. My research spans across autonomic computing, network based computing, storage systems, statistical learning, performance modeling, high performance computing, Web services, and databases.

• Research Summary

  Addressing system management problems is one of the key challenges in computer science research. Examples include system tuning, performance debugging, availability management, anomaly detection, and capacity planning. A range of application-, hardware-, and software-related factors contribute to a potentially large factor-space that affects system behavior. A careful understanding of these factors is crucial for making correct system management decisions.
  
  My research involves design and development of policies and mechanisms to understand the impact of all the relevant factors that affect system behavior, and how these factors interact with one another. The goal is to create this knowledge in a proactive, automatic, efficient, and accurate manner. In my graduate research, I have used these policies and mechanisms to address system management problems in Storage Systems, High Performance Computing (HPC), and Web Services. Selected projects are summarized here.

• Patent

  • OffloadMagic: A Model and System for a Self-configuring and Adaptive Offload Card Architecture for TCP/IP and specialized protocols, 2003.

    The benefits of offloading network protocol processing to the NIC are highly application dependent. In fact, for some applications NIC offload can lead to degraded performance. This patent presents techniques that adapt the protocol offload to a given application. This work was done at IBM Almaden Research Center with Sandeep Uttamchandani and Kaladhar Voruganti.
