Compilers, computer architectures, programming languages, etc.

I received a PhD degree in Computer Architecture from Tsinghua University in 2001, and an MS degree from Northwestern Polytechnic University in 1998. I joined the CAPSL  group led by Prof.Guang R.Gao in 2001.

My research projects have been primarily on optimizing compilers. I have been working on software pipelining of loop nests, particularly, a method called Single-dimension Software Pipelining (SSP).

I was a guest instructor for Compiler Design and Introduction to Computer Systems Engineering (CPEG421/621 and CPEG323) in 2003 and 2004. Topics include partial redundancy elimination, static single assignment form, code selection, number representation, computer arithmetic, and pipelined architectures.

I am currently working at Microsoft on Phoenix compiler framework. Phoenix is open in data structures and APIs. Therefore, compiler researchers can focuse on developing their own algorithms and put the algorithms into the compiler as a plug-in, without the pain to explore the internal details of the compiler. Please download the RDK and enjoy it in your research and teaching.
