Researchers have developed ScaleAcross Explorer, a novel optimizer designed to enhance the efficiency of large-scale AI model training across multiple data centers and regions. This approach, informed by Meta's production experience, addresses the complexities of distributing hundreds of thousands of GPUs. The optimizer systematically explores parallelism placement, scheduling, and network technologies to achieve significant training speedups, demonstrating up to 64.62% improvement over existing configurations.
