Super Node Communication

English summary

1. Core logic and technical advantages of super node industry. Background: The super node industry started solution validation and demand research in 2025. Key drivers include rapid growth of large model parameters (latest KV's K3 reaches 2.8 trillion parameters) and restrictions on overseas NV GPU procurement in China, where domestic GPU single-card performance lags overseas, requiring system-level multi-card stacking to achieve equivalent computing power. Core advantages over traditional multi-switch networking: Latency significantly reduced: 8-card scale-out via switches has microsecond latency, while 64-card super node using unified memory addressing + scale-up native interconnection achieves nanosecond latency, an order of magnitude improvement, avoiding GPU idle waste from cross-device data movement. Resource utilization efficiency improved: 64-card super node achieves unified HBM addressing; tasks can be dispatched to all GPUs at once, natively utilizing all HBM memory resources without cross-card data movement, significantly improving computing efficiency. ...
