The speed of the storage device has long lagged behind the computation speed of processors.As a result, the I/O performance of storage systems in a supercomputer fails to keep up with its computational power.
This gap continues to widen in modern supercomputers.
On future exascale supercomputers, this issue can worsen...
Machine learning is seeping into every fabric in various practical domains such as autonomous driving, wearable computing, and smart buildings. However, in the actual development and integration, especially when the learning-based components are frequently included as components of large complex systems where the physical instances can be included as interactable...

Computer systems supported by photonic interconnects and photonic memory devices can reach performance and energy efficiency levels unattainable through purely electronic means across scales, from processor chips to the data center. However, the promised benefits cannot be realized through a simple replacement process; to reach their full potential, several aspects...
Cyber-physical systems (CPS), as a multidisciplinary area, have been widely adopted in our daily life and attract experts from various fields. CPS aims to achieve real-time and resilient connection with physical world through integration of computation, communication and control technologies. Many CPS systems, such as automotive, avionics, and industrial system,...
While the entire silicon industry has been blooming under Moore’s Law for decades, conventional digital implementation is approaching the “stall” of Moore’s Law due to many physical design limitations. Technology innovation now is going to take a different direction. Given the increasing demand for emerging applications' computational capacity, it is...
Over the last few years, understanding user experience within mobile systems has become a popular phenomenon as a means to manage hardware resources. Across the many issues being studied in this area, I focus on how to utilize user satisfaction in this dissertation. Notably, I examine user experience by incorporating...
We address the problem of efficient maintenance of the answer to a new type of query: Continuous Maximizing Range-Sum (Co-MaxRS) for moving objects trajectories. The traditional static/spatial MaxRS problem finds a location for placing the centroid of a given (axes-parallel) rectangle $R$ so that the sum of the weights of...
One method of cancer treatment is to thermally ablate (destroy) tumor masses using heat caused by electric current, or Joule heating. This particular modality is called radiofrequency ablation (RFA), due to the use of electric currents in the 100 kHz to 800 kHz frequency range. Computationally, RFA is simulated as...
