The main goal of this project is to improve the performance and energy efficiency of I/O (Input/Output) operations of large-scale cluster computing platforms. The major activities include: 1) characterize the memory access workloads; 2) investigate the new and emerging new storage and memory devices, such as SSD and PCM, on I/O performance. (3) study energy-efficient buffer and cache replacement algorithms, (4) leveraging SSD as a new caching device to improve the energy efficiency and performance of I/O performanc
