I am a Computer Science Ph.D. candidate at UC Davis. My advisor is Prof. John Owens. My main research interests are 1) structure of parallelism and locality in irregular algorithms such as graph algorithms on GPU; 2) exascale computing and data analysis using Multi-GPUs. I also have broad interests on all kinds of GPU computing topics as well as computer graphics, vision, and machine learning topics. My current project on large-scale graph processing using the GPU is funded by DARPA's XDATA grant. In 2012, I did my summer internship at AMD Research on OpenCL rasterizer. In 2013 and 2014, I did my summer internship at DARPA XDATA Lab working on large-scale data analysis and graph processing.
Before coming to UC Davis, I received my B.E. degree in Computer Science and M.E. degree in Software Engineering both from Beijing University of Aeronautics and Astronautics. During my Master years, I worked on several projects on water simulation, collision detection, and distributed rendering system.
Gunrock:Fastest graph processing library on the GPU. The library is on github.
CUDA Depixelizer: A depixelization algorithm on GPU to vectorize a pixel art into a vector graph based on this paper. Source code can be found on github. Find more pictures here: Cloud, Dolphin, Dragon, and Mario with Yoshi! (Actualy, also some TMNT and Monty Python too)
Zhua: A forum crawler using Python Scrapy. My first practical Python project so far. Made with love for my lovely wife on her research topic which focuses on using data analysis and communication theory to help depressed patients. Source code can be found on github.
