Primary Research Projects
Heterogeneous computing for big data applications, University of California, San Diego Sep. 2014 – present
Advisor: Dr. Steven Swanson
§ Designed the architecture of a heterogeneous computing platform that aims at improving performance
and energy consumption for data-intensive applications using GPUs and programmable SSDs.
§ Developed the SSD firmware to process data within the storage device.
§ Implemented direct SSD to GPU data transfer in applications.
§ Advised three PhD students to develop peer-to-peer PCIe transfers, implement MapReduce framework
and support new database semantics in the prototyping system.
Data-triggered threads, University of California, San Diego
July 2008 – Sep. 2014
Advisor: Dr. Dean Tullsen
§ Designed the data-triggered threads mechanism that triggers computation as soon as the program
changes the data, and developed the simulation framework. The proposed mechanism improves the
performance of SPEC2000 applications by 46%.
§ Designed and developed a software-only runtime system that allows programs with data-triggered
threads extensions to execute on conventional processors and achieves 15% speedup on average.
§ Designed and developed a compiler framework based on LLVM that automatically analyzes and
generates data-triggered threads from an unmodified program written in C/C++.
Flash memory characterization, University of California, San Diego
Jan. 2010 – Sep. 2014
Advisor: Dr. Steven Swanson
§ Designed and developed the test platform including a custom flash controller, kernel drivers, and userspace libraries on the Xilinx Virtex-II FPGA board running a full-fledged Linux system. The test
platform allows applications to control the power and voltage supply to flash memory during operation.
§ Our experimental results demonstrate that power failure and voltage droop can lead to several nonintuitive and dangerous behaviors that can corrupt data already present in flash storage devices.
