Biography

I am advised by Prof. Emery D. Berger and a member of PLASMA group since 2007. I expect to get my Ph.D. degree in August 2013. Now I am looking for a research position either in industry or in academia.

Research Interests

Runtime systems, operating systems and compilers to improve the performance and safety of programs under multi-core environment, especially with the following focuses:

Detecting and tolerating concurrency errors: OOPSLA 2009 and More...
High performance computing: OOPSLA 2011
Deterministic multithreaded programming: SOSP 2011
Resource management of operating systems: OSDI 2008

Research Projects

Dthreads: Deterministic multithreaded library (SOSP 2011)

Sheriff: False sharing detection and mitigation (OOPSLA 2011)

Grace: Safe Multithreaded Programming for C/C++(OOPSLA 2009)

Redline: First Class Support of Interactivity in Commodity Operating Systems (OSDI 2008)

Reduce memory fragmentation:

In this project, we tackled the memory fragmentation problems in Linux operating system. By combining "memory allocation according to memory usage types" and "page migration on demand", we can greatly reduce the memory fragmentation.
