使用NVIDIA Blackwell优化Amazon SageMaker AI模型训练
Optimize model training on Amazon SageMaker AI with NVIDIA Blackwell
AWS发了篇实战教程，教你用NVIDIA Blackwell在SageMaker上调优训练，从选精度到调batch size都讲清了，搞大模型训练的人别错过。
本文介绍如何在Amazon SageMaker AI上利用NVIDIA Blackwell架构优化训练配置。包括根据模型大小（1B到64B参数）选择合适精度格式，调整batch size和序列长度以利用Blackwell扩展内存，以及策略性应用激活检查点。
通过P6-B200实例启动分布式训练，提供一套实用的训练调优框架。
Optimize model training on Amazon SageMaker AI with NVIDIA Blackwell
This post shows you how to configure training jobs on Amazon SageMaker AI to get the most out of Blackwell’s architecture on AWS. You learn how to select batch sizes and sequence lengths that take advantage of Blackwell’s expanded memory, choose the right precision format for your model size (1B to 64B parameters), and apply activation checkpointing strategically. By the end, you have a practical framework for tuning your training configuration and launching distributed training jobs on P6-B200 instances.
