Part 6/9:
Historically, the development of distributed training frameworks has been hardware-centric, with Nvidia's CUDA and its ecosystem setting industry standards. The open-source framework Megatron, developed largely by Nvidia engineers, exemplifies a well-optimized solution for scalable training. However, because it is primarily Nvidia-developed, it presents limitations for AMD hardware, often lacking the necessary tuning or bug fixes for AMD's architectures.
