profiling-communication

What problem does it solve?

This Skill detects and analyzes communication performance issues, helping optimize data transfer efficiency in Ascend NPU systems.

Core Features & Use Cases

• Communication Bottleneck Detection: Measures communication duration and identifies delays in data transfer processes.
• Performance Analysis: Provides detailed distribution reports and highlights potential bottleneck points.
• Use Case: When profiling a deep learning model's training, identify if communication overhead between host and device exceeds acceptable thresholds and implement improvements.

Quick Start

Run the analyze_communication.py script with the appropriate input directory containing CSV files to detect and analyze communication bottlenecks.
