“Firefly II” takes "task-level time-sharing" as its core concept, and the scheduling system responds in seconds, so that every researcher can have a smooth training experience. Meanwhile, the platform is equipped with powerful software layer support: high-performance arithmetic library (hfai.nn), distributed training communication framework (hfreduce), and high-capacity and high-bandwidth file system (3FS) specially designed for AI development, so that the AI model can be expanded to multiple nodes for massively parallel training, and experience the ultimate performance.
