About Me#

Hi, I’m JI, GUAN-YU.

I am a third-year Computer Science student passionate about High-Performance Computing (HPC), System Virtualization, and Low-Level Programming. My work focuses on peeling back layers of abstraction to understand—and optimize—how software interacts with hardware.

🚀 Focus Areas#

High-Performance Computing: Accelerating applications using MPI, OpenMP, and CUDA; managing clusters with Slurm.
System Software: Linux Kernel development, Device Drivers, and Virtualization technologies (Proxmox, vGPU).
Hardware & Embedded: FPGA design (Verilog) and constructing Home Lab infrastructure.

🏆 Honors & Experience#

Coach, IndySCC Student Cluster Competition 2025 (St. Louis, USA)
Global 2nd Place, ISC25 Student Cluster Competition (Hamburg, Germany)
Global Champion, APAC HPC-AI Competition
Global 2nd Prize, 2025 Apple Mobile Application Innovation Contest (MAIC)

🔧 Tinkering#

Beyond the terminal, I enjoy building physical things and exploring network technologies:

Home Lab: Maintaining self-hosted services, ZFS storage, and VoIP systems.
3D Printing: Building and tuning Voron printers.

關於我#

我是 紀冠宇 (JI, GUAN-YU)。

我是一名資訊工程系大三學生，熱衷於 高效能運算 (HPC)、系統虛擬化 以及 底層系統開發。我喜歡深入探究硬體與軟體之間的互動，並致力於系統效能的極致優化。

🚀 技術領域#

HPC 與平行運算： 熟悉 MPI、OpenMP 與 CUDA 加速，以及 Slurm 叢集管理。
系統軟體： 專注於 Linux Kernel 開發、驅動程式與虛擬化技術 (Proxmox, vGPU)。
嵌入式與硬體： 具備 FPGA (Verilog) 開發經驗，並熱衷於 Home Lab 架構設計。

🏆 經歷與榮譽#
