Scale Bitwise-Deterministic Pretraining with NVIDIA Megatron Core

NVIDIA's technical blog describes bitwise determinism for large-scale pretraining with Megatron Core, which makes training runs easier to debug, validate, and resume reproducibly.

The source says these benefits matter most for models with trillions of parameters trained across thousands of GPUs, where multiple parallelism dimensions, low-precision computation, and distributed checkpointing complicate failure reproduction and fix validation.
