  1. Our work on the open-source computer system usage and failure repository, Fresco, gets profiled in a Purdue news story.
    College of Engineering, ITaP Research Computing team studies supercomputer reliability (May 5, 2020)
    And in an NSF news story:
    Research computing team studies supercomputer reliability: Reliability required in areas such as infectious disease modeling (May 22, 2020)

(Acceptance rate: 48/291 = 16.5%)
  2. Our work on online reconfiguration for distributed databases, Sophia, gets profiled in a Purdue news story.
    System designed to improve database performance for health care, IoT (May 5, 2020)
    This work shows how one can reconfigure a distributed database when workload characteristics change. For the first time, our solution can estimate what will be the benefit of the reconfiguration and the transient performance impact of the reconfiguration, over a future window of time. It then initiates the reconfiguration only when the benefit outweighs the cost. It also maintains data availability and respects the consistency requirements throughout. The paper appeared at Usenix ATC 2019 and is under submission to the USPTO for a patent.
