Tracetto - PyTorch Profiler Trace Visualizer

Tracetto is a browser-side analysis tool for PyTorch Profiler traces. It helps performance engineers inspect GPU time, operator hotspots, kernel behavior, memory movement, and distributed workload imbalance without uploading trace data.

Tracetto 是面向 PyTorch Profiler trace 的浏览器端性能分析工具，支持在本地浏览器中解析 trace，快速定位 GPU 时间分布、operator 热点、kernel 行为、内存搬运和多 rank 负载不均问题。

Keywords: PyTorch Profiler, trace visualizer, GPU profiling, CUDA kernel analysis, WebAssembly profiler, distributed training performance.

关键词：PyTorch Profiler 可视化、torch profiler trace 分析、GPU 性能分析、CUDA kernel 分析、operator 热点、内存搬运分析、分布式训练性能分析。
