TorchTitan training health check in preview for B200 GPU clusters
You can now run a TorchTitan training health check on your GPU clusters. It runs a short training benchmark on one or more nodes and measures steady-state model FLOPs utilization (MFU) to validate end-to-end training throughput. This feature is in preview and runs on demand on NVIDIA B200 (Blackwell) nodes.
See Health checks for the available tests, thresholds, and results.
