With partnerships from Voltage Park, Dell, H5, and NVIDIA, a small team effectively set up and refined a massive cluster with 4,088 H100 GPUs for a 70B parameter model outperforming GPT-4o on reasoning tasks, by creating tools and scripts for robust host health checks, InfiniBand networking, and automating error recovery, all while detailing challenges like ECU failures, networking bottlenecks, and the complexities of maintaining a seamless distributed training environment.
