A Few GPUs, A Whole Lotta Scale: Faithful LLM Training Emulation with CrystalLLM

Large language model (LLM) training today runs on clusters spanning thousands of GPUs. While this scale enables rapid model advances, developing, debugging, and performance-tuning, the training framework inevitably becomes complex and costly. This is because engineers often need to reproduce production behaviors to dia...
