Experience
Research Assistant
- Research and Publication: Conducted innovative research in High-Performance Computing, Computer Architecture, and Parallel and Distributed Computing. Authored and published research papers in reputable academic conferences and journals.
- Mentorship and Education: Mentored both graduate and undergraduate students in their independent research studies. Provided guidance on research topics, project development, and data analysis.
- Software Development and Collaboration: Played an integral role in developing and maintaining research software and tools. Wrote, tested, and documented code for various projects. Contributed to open-source software initiatives, fostering collaborative innovation.
- Server Administration: Managed two high-end servers (Hugo and Alita) hosted at the High-Performance Computing Center. Oversaw server configuration, maintenance, and software management. Ensured consistent server availability and reliability while troubleshooting issues as they arose.
Graduate Student Intern
- Data Integration and Analysis: Integrated HPC monitoring data from diverse sources (LDMS, DCGM, Slurm, VictoriaMetrics) for comprehensive analysis of system-wide architectural efficiency, including CPU, GPU, DRAM, and HBM2 resource utilization. Identified critical trends and patterns within the data to drive insights into system performance, with a focus on NERSC’s Cori and Perlmutter.
- Machine Learning Expertise: Conducted in-depth statistical analysis of job-level monitoring data. Applied a variety of machine learning models, including SVC, LinearSVC, Decision Tree, and Random Forests, to analyze jobs based on time-series features.
- Innovative Data Processing: Pioneered a novel approach by encoding time-series monitoring data as images and trained a Convolutional Neural Network (CNN) to classify and predict job applications with high accuracy.
- Simulation and System Design: Designed and implemented a discrete event simulator to study resource management and job scheduling in HPC systems, with a specific focus on systems with disaggregated memory resources.
Graduate Student Programmer
- Website Maintenance and Communication: Maintained and updated TLPDC web pages, ensuring a fresh and relevant online presence. Facilitated communication with software application providers to meet product requirements efficiently.
