How does DeepNVMe improve training performance?

DeepNVMe optimizes data transfers between persistent storage and GPU memory using asynchronous I/O and GPUDirect Storage (GDS), significantly reducing I/O bottlenecks during model offloading.

Does this skill support different precision formats?

Yes, it includes best practices and configuration assistance for FP16, BF16, and FP8 mixed-precision training to balance speed and numerical stability.

What is the DeepSpeed skill used for?

It provides specialized guidance for distributed AI training, helping developers implement DeepSpeed features like ZeRO optimization and mixed precision to train models that exceed single-GPU capacity.

Can this skill help resolve Out-of-Memory (OOM) errors?

Yes, it provides specific implementation patterns for ZeRO-Infinity and parameter offloading, which allow for training much larger models by utilizing CPU and NVMe memory.
