Yilin Tong
Worked on the facebookresearch/param repository to enhance distributed benchmarking infrastructure, focusing on measurement accuracy, reliability, and maintainability. Developed and refined GPU device-time benchmarking options, improved command-line interface argument parsing, and introduced profiling for graph launches to enable deeper performance insights. Addressed critical bugs in paired tensor handling and communication trace replay, increasing stability for large-scale distributed runs. Applied Python, CUDA, and object-oriented programming to refactor initialization utilities, reduce code duplication, and support flexible process group configurations. Prioritized reproducibility and observability, delivering robust benchmarking tools that accelerate iteration cycles and support scalable evaluation in high-performance computing environments.

Mar 1, 2025March 2025 — Param project: Initial addition of GPU-device-time benchmarking option and subsequent rollback to CPU-based timing. Delivered a toggle (--use-device-time) to measure latency and bandwidth of collectives using the GPU clock, followed by a rollback to CPU-based timing to stabilize measurements. This maintained a robust, reproducible benchmarking baseline while enabling performance exploration when needed.
