About Us

The Power-Aware Computer Systems (PACS) laboratory at the Ohio State University is doing research in the broad area of computer systems and networks. Currently, we are focusing on three research topics: power/thermal-aware systems, real-time embedded systems, and cyber-physical systems. Our research is supported by various funding agencies such as National Science Foundation (NSF), Office of Naval Research (ONR), Microsoft Research (MSR), and IBM Research. Our lab has established long-term collaborations with researchers at IBM Research, HP Labs, Oak Ridge National Lab (ORNL), and universities in the US and worldwide.

  1. Our first research topic is power/thermal-aware computing systems. Specifically, we are developing power, thermal, and performance control algorithms for computer servers in large-scale data centers. Our previous work has made significant impacts on IBM’s server business, as our power control algorithm was directly adopted in more than a billion dollars worth (annually) of IBM servers (10+ models). Our research has been published in top conferences such as ISCA, HPCA, and RTSS. We also received the Best Paper Award at the 29th IEEE Real-Time Systems Symposium (RTSS).
  2. Our second research topic is real-time embedded systems. Currently, we are developing coordinated solutions to simultaneously meet timing and power/thermal constraints for high-performance embedded systems. Our research in this direction has been published in premier conferences such as RTSS and RTAS, as well as prestigious journals such as IEEE Transactions on Parallel and Distributed Systems and IEEE Transactions on Computers.
  3. Our third topic is cyber-physical systems and wireless sensor networks, where we are working to design real-time and high-throughput communication protocols for wireless sensor networks, and develop real-time information dissemination middleware. Our research in this direction has been published in premier conferences and journals such as SenSys, EWSN, INFOCOM, and ACM Transactions on Sensor Networks.
