The Core (Compiler Research) Lab is a research lab led by professor Hanjun Kim at POSTECH, Pohang University of Science and Technology. The focus of the Core Lab is the design of compilers and architectures to improve performance, power-efficiency, and reliability without burdening application developers.


The Compiler Optimization Project - Compiler becomes a new core of modern computer architecture. The Compiler Optimization project proposes a novel compiler system that automatically optimizes programs for different computer systems from mobile systems to cloud servers.

The Parallelization Project - As state-of-the-art smartphones, tablet, laptops and servers adopt multicore processors with GPUs, computer systems become increasingly parallel and heterogeneous. The Parallelization project investigates sequential programs that never before parallelized and finds scalable parallelism opportunities for the scalable and heterogeneous computer systems.

The Security Project - Computer systems are storehouses of personal information. As more and more personal data are stored in computer systems, ensuring the confidentiality of the private data has become a critical problem in security. The Security project proposes a co-designed compiler and computer architecture that securely protect private information.
