I’m a 4th-year PhD student at the Computer Science of UC Riverside, where I am very fortunate to be advised by Prof. Zhijia Zhao.
cuJSON is a highly parallel JSON parser that achieves 2.5x speedup over the state-of-the-art GPU JSON parser, GJSON, and 3.6x speedup over the best CPU JSON parser.
A parallel BFS system that adapts between TopDown and BottomUp traversal strategies. Achieved up to 34.6x speedup over serial BFS via hybrid partitioning and dynamic traversal.
A dynamic shortest-path algorithm combining delta* and rho-stepping for optimal parallel performance. Introduced graph classification via 4 structural metrics to automate the stepping method and parameter selection. Outperformed fixed-parameter baselines with up to 1.5x speedup on large-scale graphs.
First survey that cover the combination of Federated Learning and Generative Models.
