Explain GPU pipeline and execution hazards
GPU Architecture and Execution
This interview question assesses your understanding of modern GPU architecture and its operational principles. You should be prepared to explain the following key areas:
Graphics Pipeline
Describe the process by which a modern GPU renders a triangle, starting from its input vertices and culminating in the final pixels displayed on screen.
Execution Hazards
Explain how register read-after-write (RAW) dependencies are managed within a pipelined processor, specifically focusing on the context of a GPU's execution pipeline.
GPU Strengths
Identify the types of computational operations at which GPUs excel, and provide a detailed explanation of the underlying architectural reasons for this superior performance.
Throughout your explanation, emphasize modern graphics hardware concepts, throughput considerations, memory behavior, and execution scheduling mechanisms.
