p2p-test

What problem does it solve?

This Skill measures the bandwidth and performance of point-to-point communication between GPUs, enabling performance validation for distributed training.

Core Features & Use Cases

• Performance Testing: Conducts unidirectional and bidirectional P2P bandwidth tests between multiple GPUs.
• Use Case: For a deep learning infrastructure with multiple GPUs, quickly verify inter-GPU communication speeds to identify bottlenecks.
• Technical: Utilizes DMA-based data transfer to accurately measure GPU communication throughput.

Quick Start

Run the P2P bandwidth test by setting environment variables, navigating to the test directory, and executing the script to obtain performance metrics.
