Application-aware System Optimization Lab
Welcome to Application-aware System Optimization Lab
The Application-aware System Optimization Lab is a research lab led by professor Yongjun Park at Yonsei University. The focus of our research group is Compiler/OS/Architecture level solutions for Performance, Energy-efficiency on AI/Big Data Processing/IOT/HPC devices (ILP (VLIW, CGRA), DLP (SIMD, GPU), Neural accelerators, PIM, ISP, and heterogeneous systems).
Research Goal: Platform-specific System Design for Emerging Applications
Specific Projects
1. Compiler optimization for deep learning/big data processing (approximate computing, sparse matrix multiplication, ...) on NPUs/PIM devices/GPUs
2. Efficient multitasking support for multiple GPU/CPU/NPU/PIM programs on heterogeneous architectures
3. Neural accelerator design and compiler/OS support
4. Near-data processing: Processing-in-memory (PIM), In-storage processing (ISP)
Required Skill Set: Compilers, Computer architectures, OS
