Real-time Visibility in PyTorch Training with TraceML
Read Full Article: Real-time Visibility in PyTorch Training with TraceML
TraceML is an innovative live observability tool designed for PyTorch training, providing real-time insights into various aspects of model training. It monitors dataloader fetch times to identify input pipeline stalls, GPU step times using non-blocking CUDA events to avoid synchronization overhead, and GPU CUDA memory to detect leaks before running out of memory. The tool offers two modes: a lightweight essential mode with minimal overhead and a deeper diagnostic mode for detailed layerwise analysis. Compatible with any PyTorch model, it has been tested on LLM fine-tuning and currently supports single GPU setups, with plans for multi-GPU support in the future. This matters because it enhances the efficiency and reliability of machine learning model training by offering immediate feedback and diagnostics.

TraceML’s New Layer Timing Dashboard: Real-Time Insights
Read Full Article: TraceML’s New Layer Timing Dashboard: Real-Time Insights![[P] TraceML Update: Layer timing dashboard is live + measured 1-2% overhead on real training runs](https://www.tweakedgeek.com/wp-content/uploads/2025/12/featured-article-6363-300x171.png)
TraceML has introduced a new layer timing dashboard that provides a detailed breakdown of training times for each layer on both GPU and CPU, allowing users to identify bottlenecks in real-time. This live dashboard offers insights into where training time is allocated, differentiating between forward and backward passes and per-layer performance, with minimal overhead on training throughput. The tool is particularly useful for debugging slow training runs, identifying unexpected bottlenecks, optimizing mixed-precision setups, and understanding CPU/GPU synchronization issues. This advancement is crucial for those looking to optimize machine learning training processes and reduce unnecessary time expenditure.
