Biography

I am a computer architecture researcher in the Samsung Memory Solutions Lab (MSL) with a Ph.D. degree in Computer Science from Purdue University where I was fortunately advised by Prof. Changhee Jung. In the meanwhile, I also closely work with Prof. Dongyoon Lee at Stony Brook University, Prof. Trevor E. Carlson at National University of Singapore, and Prof. Jongouk Choi at University of Central Florida. Prior to joining Purdue University, I worked as a compiler engineer with focuses on optimizing the middle-end and backend of GCC (GNU Compiler Collection) for CSKY architecture (an embedded architecture widely used in network switch, printer, etc) of Alibaba T-Head Semiconductor.

Research

As a computer architecture researcher in the Samsung MSL, I work on hardware/software co-design for high-performance memory products, such as next generation high bandwidth memory (HBM), CXL (Computing eXpress Link)-based memory, and their applications for GPUs and artificial intelligence. While I was a Ph.D. student at Purdue University, I designed reliable and performant computing systems, ranging from embedded systems to server-class systems, against soft errors and crash consistency issues resulting from power failures. To achieve that, I usually co-design compilers and architectures to maintain minimal hardware complexity while achieving high performance. My research works are typically published at top-tier conferences in the fields of computer architecture, high-performance computing (HPC), and programming languages, e.g., ISCA, MICRO, ICS, HPDC, and PLDI.

5 first-author publications in top computer architecture/HPC conferences: (1) MICRO'21x2, (2) MICRO'23, (3) ISCA'24, (4) ICS'24.
6 second-author publications in top computer system conferences: (1) PLDI'20, (2) HPDC'22, (3) ISCA'23, (4) MICROx2, (5) RTSS'23.

Working Experience

Computer Architecture Researcher: August 2024 - Present, Samsung Memory Solutions Lab (MSL).
Research Intern: May 2023 - August 2023, Samsung Memory Solutions Lab (MSL) managed by Dr. Yang Seok Ki.
I interned at Samsung MSL to design a more energy-efficiency ECC DRAM while maintaining its reliability.
Research Intern: May 2022 - August 2022, Alibaba DAMO Academy, Computing Technology Lab directed by Prof. Yuan Xie.
I worked on optimizing the ARM memory fence instructions, which is particular of importance for the server cores scaling up to 256 cores. This is because ARM processor is now prevalent in server fleets due to its energy-efficiency and low license cost. However, the memory fences, highly affecting the performance of multi-threaded applications, on ARM cores are not optimized in contemporary ARM server processors.
Senior Compiler Engineer: Dec 2017 - July 2018, Alibaba T-Head Semiconductor.
After obtaining my Master degree from HUST, I worked at Alibaba T-Head as a senior compiler engineer with the focus on analyzing and uncovering the performance bottleneck of GCC for CSKY architecture in terms of run-time performance and code size. What I did is fixing a series of performance bugs of GCC for CSKY in GCC's local register allocation and its naive instruction selector though there is a post-isel phase to combine multiple simple instructions into a more sophisticated form.
Senior Software Engineer: June 2017 - Dec 2017, Alibaba Taobao BU.
I worked there to design a static analyzer for C/C++/Objective-C/Objective-C++ based on Clang, which is widely used for statically validating the correctness and ensuring the robustness of Taobao App (the most popular online shopping application in China).
Software Engineer Intern: June 2016 - August 2016, Alibaba Group.
During the summer 2016, I interned at Alibaba Group to develop a prototype (so-called StaticJS) that optimizes the performance of Google V8 JavaScript Virtual Machine. That is, StaticJS annotates program variables with type information and then passes the type information to the middle-end optimizations and code generation. As such, StaticJS avoids the drawbacks of dynamic typing in JavaScript to some extent and achieves higher performance transparently.
