LLM training checkpoints are massive (782 GB for a 70B model) and frequent, making them a significant cost driver. Synchronous checkpoint writes idle all GPUs during saves — at 128 B200s training a 405B model, this costs over $200,000/month. NVIDIA nvCOMP, a GPU-accelerated lossless compression library, can reduce checkpoint
