GPU Roofline Model Study for a Computer Vision Inference Workload
Overview
What this challenge is about.
Construct empirical roofline plots for the current GPU (A100-class) and next-gen GPU (H100-class) using vendor-published peak FLOPs and measured peak memory bandwidth. Profile the ResNet-50 inference workload at batch sizes 1, 8, 32, and 128 with Nsight Compute, capturing arithmetic intensity, achieved FLOPs/s, and achieved memory bandwidth per kernel. Place each (batch, GPU) point on the roofline. Identify compute-bound vs. memory-bound regimes per batch size. Deliver the roofline plots, per-kernel profiling tables, and a 10-page placement recommendation memo.
The Brief
What you'll do, and what you'll demonstrate.
Build empirical roofline models for two GPU generations, profile a ResNet-50 inference workload, and recommend batch-size-and-SKU placement.
Earning criteria — what you'll demonstrate
- Construct an empirical roofline model from measured peak FLOPs and bandwidth
- Profile a real GPU workload with Nsight Compute
- Map workload regimes to GPU SKUs based on arithmetic intensity
- Communicate placement recommendations to a capacity team
