- I’m currently a Ph.D. student at Shanghai Jiao Tong University, Dept. of Computer Science and Engineering. I’m supervised by Prof. Jingwen Leng, and I mainly research on computer architecture, AI system, compiler and optimization. My interests include chip design, compiler optimization, computer organization and system architecture. Learn more on my CV.

- National Key Research Project (2018-2020): Deep learning accelerator compiler tool-chain development
- I develop a tool chain for Cambricon MLU-100 from front-end (ONNX) to back-end codegen (DNN operator library) and conduct corresponding optimizations including operator fusion, spatial multiplexing, etc. I’m responsible for all code development, testing, and document editing.
- R&D Project from Industry (2021): Heterogeneus accelerator compiler tool-chain design
- I research, verify and give a design of a compiler tool-chain for a heterogeneous accelerator developed by Montage Inc. The accelerator includes a RISC-V CPU, a SIMD unit programmed by OpenCL, and a matrix accelerator. The design includes task partition, dispatching and workload balancing strategy, heterogeneous code generation strategy, etc. I’m responsible for all code development, testing, and most of the document editing.
- Course Project (B.S.): Compiler front-end of a C-alike language
- I develop a compiler front-end of a C-alike language using lex and yacc, the generated intermediate representation is executed on a interpreter.
- Course Project (B.S. Thesis): Profiling and optimization of Tensor Core on Turing GPUs
- I conduct a research on Tensor Core on Turing GPUs via profiling, according to the result and insight I achieved, I conduct some simple code optimization on an AI framework.
