 ## Performance
 We measured the examples from the above demo on both A800s and H800s. Each machine has 8 GPUs, with a TP size set to 8. The table below shows the performance comparison between flux and torch+nccl. It can be observed that by overlapping fine-grained computation and communication, Flux is able to effectively hide a significant portion of the communication time
